Problem: Please answer a question about the following article about Botany:
Cytokinins are a class of plant hormones named for their control of cell division or cytokinesis. The natural cytokinin zeatin was discovered in corn, Zea mays, and is a derivative of the purine adenine. Zeatin is produced in roots and transported to shoots in the xylem where it promotes cell division, bud development, and the greening of chloroplasts. The gibberelins, such as Gibberelic acid are diterpenes synthesised from acetyl CoA via the mevalonate pathway. They are involved in the promotion of germination and dormancy-breaking in seeds, in regulation of plant height by controlling stem elongation and the control of flowering. Abscisic acid (ABA) occurs in all land plants except liverworts, and is synthesised from carotenoids in the chloroplasts and other plastids. It inhibits cell division, promotes seed maturation, and dormancy, and promotes stomatal closure. It was so named because it was originally thought to control abscission. Ethylene is a gaseous hormone that is produced in all higher plant tissues from methionine. It is now known to be the hormone that stimulates or regulates fruit ripening and abscission, and it, or the synthetic growth regulator ethephon which is rapidly metabolised to produce ethylene, are used on industrial scale to promote ripening of cotton, pineapples and other climacteric crops.
Where are cytokinins produced?
A: in roots

Napoleon's coronation took place on December 2, 1804. Two separate crowns were brought for the ceremony: a golden laurel wreath recalling the Roman Empire and a replica of Charlemagne's crown. Napoleon entered the ceremony wearing the laurel wreath and kept it on his head throughout the proceedings. For the official coronation, he raised the Charlemagne crown over his own head in a symbolic gesture, but never placed it on top because he was already wearing the golden wreath. Instead he placed the crown on Josephine's head, the event commemorated in the officially sanctioned painting by Jacques-Louis David. Napoleon was also crowned King of Italy, with the Iron Crown of Lombardy, at the Cathedral of Milan on May 26, 1805. He created eighteen Marshals of the Empire from amongst his top generals to secure the allegiance of the army.

How many crowns were used in Napoleon's coronation ceremony?
Answer: Two

Problem: In the resulting Battle of Pusan Perimeter (AugustSeptember 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny materiel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.
What did the US Air Force's daytime attacks cause the KPA to do?
The answer is the following: to hide in tunnels by day and move only at night

The discovery of new maritime trade routes by Western European states allowed them to avoid the Ottoman trade monopoly. The Portuguese discovery of the Cape of Good Hope in 1488 initiated a series of Ottoman-Portuguese naval wars in the Indian Ocean throughout the 16th century. The Somali Muslim Ajuran Empire, allied with the Ottomans, defied the Portuguese economic monopoly in the Indian Ocean by employing a new coinage which followed the Ottoman pattern, thus proclaiming an attitude of economic independence in regard to the Portuguese.
Avoiding the strength of Ottoman trade was accomplished with the discovery of what?
new maritime trade routes

Input: Endangered Species Act
The Endangered Species Act of 1973 (ESA; 16 U.S.C. 1531 et seq.) is one of the few dozens of United States environmental laws passed in the 1970s, and serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The ESA was signed into law by President Richard Nixon on December 28, 1973, it was designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation." The U.S. Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration (NOAA).

Which president signed the Act into law?
Output: Richard Nixon

Problem: Please answer a question about the following article about Animal:
Animals are generally considered to have evolved from a flagellated eukaryote. Their closest known living relatives are the choanoflagellates, collared flagellates that have a morphology similar to the choanocytes of certain sponges. Molecular studies place animals in a supergroup called the opisthokonts, which also include the choanoflagellates, fungi and a few small parasitic protists. The name comes from the posterior location of the flagellum in motile cells, such as most animal spermatozoa, whereas other eukaryotes tend to have anterior flagella.
It is believed that animals evolved from what?
A:
a flagellated eukaryote
