input: Please answer the following: Information:  - The Sikorsky S - 39 was a smaller , single - engine version of the S - 38 light amphibious aircraft , built in the USA by aviation firm Sikorsky Aircraft during the early 1930s .  - The Sikorsky Aircraft Corporation is an American aircraft manufacturer based in Stratford, Connecticut. It was established by Igor Sikorsky in 1925 and was among the first companies to manufacture helicopters for civilian and military use.  - On boats and ships, keel can refer to either of two parts: a structural element that sometimes resembles a fin and protrudes below a boat along the central line, or a hydrodynamic element. These parts overlap. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Only the ship's launching is considered more significant in its creation.  - An amphibious aircraft or amphibian is an aircraft that can take off and land on both land and water. Fixed-wing amphibious aircraft are seaplanes (flying boats and floatplanes) that are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared to planes designed for land or water only. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up and are dubbed tri-phibians.  - A flying boat is a fixed-winged seaplane with a hull, allowing it to land on water, that usually has no type of landing gear to allow operation on land. It differs from a floatplane as it uses a purpose-designed fuselage which can float, granting the aircraft buoyancy. Flying boats may be stabilized by under-wing floats or by wing-like projections (called sponsons) from the fuselage. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during World War II. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used for maritime patrol and air-sea rescue.  - An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.  - A floatplane (float plane or pontoon plane) is a type of seaplane, with one or more slender pontoons (known as "floats") mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft.  - Stratford is a town in Fairfield County, Connecticut, United States, located on Long Island Sound at the mouth of the Housatonic River. Stratford is in the Bridgeport-Stamford-Norwalk Metropolitan Statistical Area. It was founded by Puritans in 1639.  - Igor Ivanovich Sikorsky ("Ígor' Ivánovi Sikórskij" "Ihor Ivanovych Sikorskyi"; May 25, 1889  October 26, 1972), was a Russian-American aviation pioneer in both helicopters and fixed-wing aircraft. First success came with the S-2, the second fixedwing plane of his design and construction. His fifth airplane, the S-5, won him national recognition as well as F.A.I. license Number 64. His S-6-A received the highest award at the 1912 Moscow Aviation Exhibition. and in the fall of that year the aircraft won for its young designer, builder and pilot first prize in the military competition at Petrograd.

input: Please answer the following: Information:  - An advocate is a type of professional person in several different legal systems and it is also a commonly used "honorific" for remarkable lawyers, such as in "Adv. Sir Alberico Gentili". The broad equivalent in many English law-based jurisdictions can be a "barrister". However, in Scottish, South African, Italian, French, Spanish, Portuguese, Scandinavian, Polish, South Asian and South American jurisdictions, advocate is also a word to indicate lawyers of superior classification.  - South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil).  - Ali Lenin Aguilera Marciales ( born 1967 in Caracas , Venezuela ) is a Venezuelan lawyer , entrepreneur , and a Strategic Business Development Consultant .  - A lawyer is a person who practices law, as an advocate, barrister, attorney, counselor or solicitor or chartered legal executive. Working as a lawyer involves the practical application of abstract legal theories and knowledge to solve specific individualized problems, or to advance the interests of those who hire lawyers to perform legal services.  - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.  - Guyana (pronounced or ), officially the Co-operative Republic of Guyana, is a sovereign state on the northern mainland of South America. It is, however, included in the Caribbean Region due to its strong cultural, historical, and political ties with the Caribbean Community (CARICOM). Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Suriname to the east and Venezuela to the west. With , Guyana is the fourth-smallest country on mainland South America after Uruguay, Suriname and French Guiana.  - Venezuela, officially the Bolivarian Republic of Venezuela, is a federal republic located on the northern coast of South America. It is bordered by Colombia on the west, Brazil on the south, Guyana on the east, and the islands of Trinidad and Tobago to the north-east. Venezuela's territory covers around with an estimated population . Venezuela is considered a state with extremely high biodiversity (currently ranks 7th in the world's list of nations with the most number of species), with habitats ranging from the Andes Mountains in the west to the Amazon Basin rain-forest in the south, via extensive "llanos" plains and Caribbean coast in the center and the Orinoco River Delta in the east.
