Input: Read this: The geologic record of the Proterozoic (2,500 to 541 million years ago) is more complete than that for the preceding Archean. In contrast to the deep-water deposits of the Archean, the Proterozoic features many strata that were laid down in extensive shallow epicontinental seas; furthermore, many of these rocks are less metamorphosed than Archean-age ones, and plenty are unaltered. Study of these rocks show that the eon featured massive, rapid continental accretion (unique to the Proterozoic), supercontinent cycles, and wholly modern orogenic activity. Roughly 750 million years ago, the earliest-known supercontinent Rodinia, began to break apart. The continents later recombined to form Pannotia, 600540 Ma.
Question: What era came before the Proterozoic era?

Output: Archean

Input: Read this: Manhattan's skyline, with its many skyscrapers, is universally recognized, and the city has been home to several of the tallest buildings in the world. As of 2011, New York City had 5,937 high-rise buildings, of which 550 completed structures were at least 330 feet (100 m) high, both second in the world after Hong Kong, with over 50 completed skyscrapers taller than 656 feet (200 m). These include the Woolworth Building (1913), an early gothic revival skyscraper built with massively scaled gothic detailing.
Question: What city has the most high-rise buildings in the world?

Output: Hong Kong

Input: Read this: By 326 BC, Alexander the Great had conquered Asia Minor and the Achaemenid Empire and had reached the northwest frontiers of the Indian subcontinent. There he defeated King Porus in the Battle of the Hydaspes (near modern-day Jhelum, Pakistan) and conquered much of the Punjab. Alexander's march east put him in confrontation with the Nanda Empire of Magadha and the Gangaridai of Bengal. His army, exhausted and frightened by the prospect of facing larger Indian armies at the Ganges River, mutinied at the Hyphasis (modern Beas River) and refused to march further East. Alexander, after the meeting with his officer, Coenus, and learning about the might of Nanda Empire, was convinced that it was better to return.
Question: Who did Alexander defeat in the area now Pakistan?

Output:
King Porus
