Input: Read this: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Question: What increases with elevation in the tropasphere?

Output: unanswerable

Input: Read this: In general, German bombers were likely to get through to their targets without too much difficulty. It was to be some months before an effective night fighter force would be ready, and anti-aircraft defences only became adequate after the Blitz was over, so ruses were created to lure German bombers away from their targets. Throughout 1940, dummy airfields were prepared, good enough to stand up to skilled observation. A number[clarification needed] of bombs fell on these diversionary ("Starfish") targets.
Question: What was the name given to these dummy airfields?

Output: Starfish

Input: Read this: In January 1790, Burke read Dr. Richard Price's sermon of 4 November 1789 entitled, A Discourse on the Love of our Country, to the Revolution Society. That society had been founded to commemorate the Glorious Revolution of 1688. In this sermon Price espoused the philosophy of universal "Rights of Men". Price argued that love of our country "does not imply any conviction of the superior value of it to other countries, or any particular preference of its laws and constitution of government". Instead, Price asserted that Englishmen should see themselves "more as citizens of the world than as members of any particular community".
Question: When did Price read Burke's sermon?

Output: unanswerable

Input: Read this: The concept's origins can potentially be traced back further. Jewish law includes several considerations whose effects are similar to those of modern intellectual property laws, though the notion of intellectual creations as property does not seem to exist notably the principle of Hasagat Ge'vul (unfair encroachment) was used to justify limited-term publisher (but not author) copyright in the 16th century. In 500 BCE, the government of the Greek state of Sybaris offered one year's patent "to all who should discover any new refinement in luxury".
Question: How long was a patent valid in Sybaris?

Output:
one year
