Input: Read this: The Late Cretaceous spans from 100 million to 65 million years ago. The Late Cretaceous featured a cooling trend that would continue on in the Cenozoic period. Eventually, tropics were restricted to the equator and areas beyond the tropic lines featured extreme seasonal changes in weather. Dinosaurs still thrived as new species such as Tyrannosaurus, Ankylosaurus, Triceratops and Hadrosaurs dominated the food web. In the oceans, Mosasaurs ruled the seas to fill the role of the Ichthyosaurs, and huge plesiosaurs, such as Elasmosaurus, evolved. Also, the first flowering plants evolved. At the end of the Cretaceous, the Deccan traps and other volcanic eruptions were poisoning the atmosphere. As this was continuing, it is thought that a large meteor smashed into earth, creating the Chicxulub Crater in an event known as the K-T Extinction, the fifth and most recent mass extinction event, in which 75% of life on earth went extinct, including all non-avian dinosaurs. Everything over 10 kilograms went extinct. The age of the dinosaurs was over.
Question: Which dinosaurs help pollute the atmosphere?

Output: unanswerable

Input: Read this: In January 1953, Nasser overcame opposition from Naguib and banned all political parties, creating a one-party system under the Liberation Rally, a loosely structured movement whose chief task was to organize pro-RCC rallies and lectures, with Nasser its secretary-general. Despite the dissolution order, Nasser was the only RCC member who still favored holding parliamentary elections, according to his fellow officer Abdel Latif Boghdadi. Although outvoted, he still advocated holding elections by 1956. In March 1953, Nasser led the Egyptian delegation negotiating a British withdrawal from the Suez Canal.
Question: What did Nasser and naguib ban in 1953?

Output: all political parties

Input: Read this: Humans and animals exposed to vacuum will lose consciousness after a few seconds and die of hypoxia within minutes, but the symptoms are not nearly as graphic as commonly depicted in media and popular culture. The reduction in pressure lowers the temperature at which blood and other body fluids boil, but the elastic pressure of blood vessels ensures that this boiling point remains above the internal body temperature of 37 C. Although the blood will not boil, the formation of gas bubbles in bodily fluids at reduced pressures, known as ebullism, is still a concern. The gas may bloat the body to twice its normal size and slow circulation, but tissues are elastic and porous enough to prevent rupture. Swelling and ebullism can be restrained by containment in a flight suit. Shuttle astronauts wore a fitted elastic garment called the Crew Altitude Protection Suit (CAPS) which prevents ebullism at pressures as low as 2 kPa (15 Torr). Rapid boiling will cool the skin and create frost, particularly in the mouth, but this is not a significant hazard.
Question: What prevents body rupture at low altitude when human body is bloated by gas bubbles?

Output: tissues are elastic and porous

Input: Read this: The greatest number of surviving Gothic buildings are churches. These range from tiny chapels to large cathedrals, and although many have been extended and altered in different styles, a large number remain either substantially intact or sympathetically restored, demonstrating the form, character and decoration of Gothic architecture. The Gothic style is most particularly associated with the great cathedrals of Northern France, the Low Countries, England and Spain, with other fine examples occurring across Europe.
Question: What country no longer has examples of Gothic buildings?

Output:
unanswerable
