Q: Context: Vatican City , officially Vatican City State or the State of Vatican City, is a walled enclave within the city of Rome. With an area of approximately 44 hectares (110 acres), and a population of 842, it is the smallest State in the world by both area and population, but formally it is not sovereign, sovereignty being held by the Holy See, the only entity of public international law that has diplomatic relations with almost every country in the world., A mediterranean climate or dry summer climate is the climate typical of the lands in the Mediterranean Basin. The lands around the Mediterranean Sea form the largest area where this climate type is found, but it also is found in most of coastal California, in parts of Western and South Australia, in southwestern South Africa, sections of Central Asia, and in central Chile., Zagreb is the capital and the largest city of Croatia. It is located in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb lies at an elevation of approximately above sea level. In the last official census of 2011 the population of the City of Zagreb was 792,875. The wider Zagreb metropolitan area includes the City of Zagreb and the separate Zagreb County bringing the total metropolitan area population up to 1,237,887. It is the biggest metropolitan area in Croatia, and the only one with a population of over one million., A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to evolve gasses, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times the Earth's diameter, while the tail may stretch one astronomical unit. If sufficiently bright, a comet may be seen from the Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures., Croats are a nation and South Slavic ethnic group at the crossroads of Central Europe, Southeast Europe, and the Mediterranean Sea. Croats mainly live in Croatia and Bosnia and Herzegovina, but are an officially recognized minority in Austria, Czech Republic, Hungary, Italy, Montenegro, Romania, Serbia, and Slovakia. Responding to political, social and economic pressure, many Croats have migrated throughout Europe (especially Germany, Austria, Switzerland, France and Italy) and the Americas (particularly the United States, Canada, Argentina, and Chile), establishing a diaspora., An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside of the scope of Earth. They look at stars, planets, moons, comets and galaxies, as well as many other celestial objects  either in observational astronomy, in analyzing the data or in theoretical astronomy. Examples of topics or fields astronomers work on include: planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. There are also related but distinct subjects like physical cosmology which studies the Universe as a whole., A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralised government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected to any other power or state., Theoretical astronomy is the use of the analytical models of physics and chemistry to describe astronomical objects and astronomical phenomena., Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism., A planet is an astronomical body orbiting a star or stellar remnant that
The term "planet" is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such., The Associazione Friulana di Astronomia e Meteorologia (AFAM) is a non-profit cultural association whose goal is the promotion of astronomy and meteorology to the public and the development of scientific research activities, often in collaboration with professional scientists.
Established in 1969, now AFAM has its own operating structures in Remanzacco (Friuli, Italy). , Remanzacco is a "comune" (municipality) in the Province of Udine in the Italian region Friuli-Venezia Giulia, located about northwest of Trieste and about northeast of Udine. As of 31 December 2004, it had a population of 5,774 and an area of ., Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state., Pordenone (Venetian and Friulian: "Pordenon") is the main "comune" of Pordenone province of northeast Italy in the Friuli-Venezia Giulia region., A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power., Giovanni Sostero ( 18 March 1964 -- 6 December 2012 ) was an Italian amateur astronomer . He was one of the leading members of the Associazione Friulana di Astronomia e Meteorologia ( Friuli , Italy ) . He was an honorary member of the Astronomical Observatory of Visnjan ( Croatia ) , too . Sostero was very active as a public out - reacher and has published some scientific works in professional astronomical journals . He had over 1880 NASA ADS citations for his work . His main research fields were the minor bodies of the Solar System ( asteroids and comets ) and variable stars ( symbiotic stars and supernovae ) . In particular , he discovered several supernovae : 2009jp , 2008ae , 2008F , 2007cl , 2006br , 2006bm , 2006H , 2006B , 2005ly , 2005kz , 2005kc . In 2000 he co-discovered a nova in the galaxy M31 . The asteroid 9878 Sostero ( 1994 FQ ) was named after him . He died on 6 December 2012 due to the complications of a heart attack . He was 48 years old . The `` Giovanni Sostero Award '' was created in 2013 and supported thereafter by Elettra - Sincrotrone Trieste to honor Sostero , formerly in charge of the soft x-ray metrology laboratory at the facility ., San Marino, officially the Republic of San Marino, also known as the Most Serene Republic of San Marino, is an enclaved microstate surrounded by Italy, situated on the Italian Peninsula on the northeastern side of the Apennine Mountains. Its size is just over , with a population of 33,562. Its capital is the City of San Marino and its largest city is Dogana. San Marino has the smallest population of all the members of the Council of Europe., France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux., Friuli is an area of Northeast Italy with its own particular cultural and historical identity. It comprises the major part of the autonomous region Friuli-Venezia Giulia, i.e. the administrative provinces of Udine, Pordenone, and Gorizia, excluding Trieste., The Mediterranean Sea (pronounced ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water., Friuli-Venezia Giulia is one of the 20 regions of Italy, and one of five autonomous regions with special statute. The capital is Trieste. (Note that Venezia, i.e. Venice, is "not" in this region, despite the name.) It has an area of 7,858 km² and about 1.2 million inhabitants. A natural opening to the sea for many Central European countries, the region is traversed by the major transport routes between the east and west of southern Europe. It encompasses the historical-geographical region of Friuli and a small portion of the historical region of Venezia Giulia (known in English also as Julian March), each with its own distinct history, traditions and identity. The name of the region was spelled FriuliVenezia Giulia until 2001, when, in connection with a modification of article nr. 116 of the Italian constitution, the official spelling "Friuli Venezia Giulia" was adopted., Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole., Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets., A boot is a type of footwear and a specific type of shoe. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials. Boots are worn both for their functionality  protecting the foot and leg from water, extreme cold, mud or hazards (e.g., work boots may protect wearers from chemicals or use a steel toe) or providing additional ankle support for strenuous activities with added traction requirements (e.g., hiking)  and for reasons of style and fashion., Slovenia, officially the Republic of Slovenia (Slovene: , abbr.: "RS"), is a nation state in southern Central Europe, located at the crossroads of main European cultural and trade routes. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and the Adriatic Sea to the southwest. It covers and has a population of 2.06 million. It is a parliamentary republic and a member of the United Nations, European Union, and NATO. The capital and largest city is Ljubljana., Gorizia (, Friulian: "Guriza") is a town and "comune" in northeastern Italy, in the autonomous region of Friuli Venezia Giulia. It is located at the foot of the Julian Alps, bordering Slovenia. It is the capital of the Province of Gorizia and a local center of tourism, industry, and commerce. Since 1947, a twin town of Nova Gorica has developed on the other side of the modern-day ItalianSlovenian border. The entire region was subject to territorial dispute between Italy and Yugoslavia after World War II: after the new boundaries were established in 1947 and the old town was left to Italy, Nova Gorica was built on the Yugoslav side. Taken together, the two towns constitute a conurbation, which also includes the Slovenian municipality of Šempeter-Vrtojba. Since May 2011, these three towns are joined in a common trans-border metropolitan zone, administered by a joint administration board., Udine ( , ) is a city and "comune" in northeastern Italy, in the middle of the Friuli-Venezia Giulia region, between the Adriatic Sea and the Alps ("Alpi Carniche"), less than from the Slovenian border. Its population was 99,244 in 2016, 176,000 with the urban area., A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes., Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. 
The country is situated in Western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of . While the Alps occupy the greater part of the territory, the Swiss population of approximately eight million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva., Physical cosmology is the study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its origin, structure, evolution, and ultimate fate. Cosmology as a science originated with the Copernican principle, which implies that celestial bodies obey identical physical laws to those on Earth, and Newtonian mechanics, which first allowed us to understand those physical laws. Physical cosmology, as it is now understood, began with the development in 1915 of Albert Einstein's general theory of relativity, followed by major observational discoveries in the 1920s: first, Edwin Hubble discovered that the universe contains a huge number of external galaxies beyond our own Milky Way; then, work by Vesto Slipher and others showed that the universe is expanding. These advances made it possible to speculate about the origin of the universe, and allowed the establishment of the Big Bang Theory, by Georges Lemaitre, as the leading cosmological model. A few researchers still advocate a handful of alternative cosmologies; however, most cosmologists agree that the Big Bang theory explains the observations better., The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan peninsula and the Apennine Mountains from the Dinaric Alps and adjacent ranges. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Montenegro and Slovenia. The Adriatic contains over 1,300 islands, mostly located along its eastern, Croatian, coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because the Adriatic collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from in summer to in winter, significantly moderating the Adriatic Basin's climate., Meteorology is the interdisciplinary scientific study of the atmosphere. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It wasn't until after the elucidation of the laws of physics and, more particularly, the development of the computer, allowing for the automated solution of a great many equations that model the weather, in the latter half of the 20th century that significant breakthroughs in weather forecasting were achieved., The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy. The size of the entire Universe is unknown., Observational astronomy is a division of the astronomical science that is concerned with recording data, in contrast with theoretical astrophysics, which is mainly concerned with finding out the measurable implications of physical models. It is the practice of observing celestial objects by using telescopes and other astronomical apparatus., The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency., Trieste is a city and seaport in northeastern Italy. It is situated towards the end of a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia, which lies almost immediately south and east of the city. It is also located near Croatia some further south. Trieste is located at the head of the Gulf of Trieste and throughout history it has been influenced by its location at the crossroads of Latin, Slavic, and Germanic cultures. In 2009, it had a population of about 205,000 and it is the capital of the autonomous region Friuli-Venezia Giulia and the Province of Trieste., Subject: giovanni sostero, Relation: place_of_birth, Options: (A) africa (B) albert (C) anatolia (D) argentina (E) atlantic ocean (F) australia (G) austria (H) belgium (I) bosnia and herzegovina (J) california (K) center (L) central (M) central asia (N) ceres (O) commerce (P) council (Q) croatia (R) enter (S) estonia (T) finland (U) france (V) french guiana (W) friuli (X) gorizia (Y) greece (Z) ireland ([) island (\) italy (]) liechtenstein (^) loose (_) lyon (`) march (a) marseille (b) netherlands (c) north africa (d) of (e) once (f) otranto (g) pacific (h) paris (i) peninsula (j) pordenone (k) republic (l) romania (m) rome (n) san marino (o) serbia (p) slovakia (q) slovenia (r) south australia (s) spain (t) switzerland (u) the americas (v) toulouse (w) trieste (x) udine (y) union (z) yugoslavia ({) zagreb (|) zürich
