Q: Extract the answer to the question from the following context. Question: What does it mean to observe specular reflection? Context: The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.
A: sees both the real antenna and an image of the antenna under the ground

Question: Extract the answer to the question from the following context. Question: Which city had a smaller assembly of people on January 22, 1989? Context: In Ukraine, Lviv and Kiev celebrated Ukrainian Independence Day on January 22, 1989. Thousands gathered in Lviv for an unauthorized moleben (religious service) in front of St. George's Cathedral. In Kiev, 60 activists met in a Kiev apartment to commemorate the proclamation of the Ukrainian People's Republic in 1918. On February 11–12, 1989, the Ukrainian Language Society held its founding congress. On February 15, 1989, the formation of the Initiative Committee for the Renewal of the Ukrainian Autocephalous Orthodox Church was announced. The program and statutes of the movement were proposed by the Writers Association of Ukraine and were published in the journal Literaturna Ukraina on February 16, 1989. The organization heralded Ukrainian dissidents such as Vyacheslav Chornovil.
Answer: Kiev

[Q]: Extract the answer to the question from the following context. Question: Engineers used brick for ballast when? Context: Punjab during Mahabharata times was known as Panchanada. Punjab was part of the Indus Valley Civilization, more than 4000 years ago. The main site in Punjab was the city of Harrapa. The Indus Valley Civilization spanned much of what is today Pakistan and eventually evolved into the Indo-Aryan civilisation. The Vedic civilisation flourished along the length of the Indus River. This civilisation shaped subsequent cultures in South Asia and Afghanistan. Although the archaeological site at Harappa was partially damaged in 1857 when engineers constructing the Lahore-Multan railroad used brick from the Harappa ruins for track ballast, an abundance of artefacts have nevertheless been found. Punjab was part of the great ancient empires including the Gandhara Mahajanapadas, Achaemenids, Macedonians, Mauryas, Kushans, Guptas, and Hindu Shahi. It also comprised the Gujar empire for a period of time, otherwise known as the Gurjara-Pratihara empire. Agriculture flourished and trading cities (such as Multan and Lahore) grew in wealth.

[A]: constructing the Lahore-Multan railroad

input: Please answer the following: Extract the answer to the question from the following context. Question: What is the first 2nd and 3rd bird mentioned with a short incubation? Context: Incubation, which optimises temperature for chick development, usually begins after the last egg has been laid. In monogamous species incubation duties are often shared, whereas in polygamous species one parent is wholly responsible for incubation. Warmth from parents passes to the eggs through brood patches, areas of bare skin on the abdomen or breast of the incubating birds. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as 83 grams (2.9 oz) of body weight per day of incubation. The warmth for the incubation of the eggs of megapodes comes from the sun, decaying vegetation or volcanic sources. Incubation periods range from 10 days (in woodpeckers, cuckoos and passerine birds) to over 80 days (in albatrosses and kiwis).
++++++++++
output: woodpeckers, cuckoos and passerine

Please answer this: Extract the answer to the question from the following context. Question: What was the motivation behind inventing the Leyden jar? Context: In October 1745, Ewald Georg von Kleist of Pomerania, Germany, found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar. Von Kleist's hand and the water acted as conductors, and the jar as a dielectric (although details of the mechanism were incorrectly identified at the time). Von Kleist found that touching the wire resulted in a powerful spark, much more painful than that obtained from an electrostatic machine. The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor, which was named the Leyden jar, after the University of Leiden where he worked. He also was impressed by the power of the shock he received, writing, "I would not take a second shock for the kingdom of France."
++++++++
Answer: charge could be stored

Question: Extract the answer to the question from the following context. Question: How did Calvin and his followers view politics? Context: Politically, Calvin favoured a mixture of aristocracy and democracy. He appreciated the advantages of democracy: "It is an invaluable gift, if God allows a people to freely elect its own authorities and overlords." Calvin also thought that earthly rulers lose their divine right and must be put down when they rise up against God. To further protect the rights of ordinary people, Calvin suggested separating political powers in a system of checks and balances (separation of powers). Thus he and his followers resisted political absolutism and paved the way for the rise of modern democracy. Besides England, the Netherlands were, under Calvinist leadership, the freest country in Europe in the seventeenth and eighteenth centuries. It granted asylum to philosophers like Baruch Spinoza and Pierre Bayle. Hugo Grotius was able to teach his natural-law theory and a relatively liberal interpretation of the Bible.
Answer:
resisted political absolutism and paved the way for the rise of modern democracy
