Input: Bird migration
Aristotle however suggested that swallows and other birds hibernated. This belief persisted as late as 1878, when Elliott Coues listed the titles of no less than 182 papers dealing with the hibernation of swallows. Even the "highly observant" Gilbert White, in his posthumously published 1789 The Natural History of Selborne, quoted a man's story about swallows being found in a chalk cliff collapse "while he was a schoolboy at Brighthelmstone", though the man denied being an eyewitness. However, he also writes that "as to swallows being found in a torpid state during the winter in the Isle of Wight or any part of this country, I never heard any such account worth attending to", and that if early swallows "happen to find frost and snow they immediately withdraw for a time—a circumstance this much more in favour of hiding than migration", since he doubts they would "return for a week or two to warmer latitudes".

Who wrote 182 papers dealing with the hibernation of swallows?
Output: Elliott Coues

Input: Armenia
Turkey also has a long history of poor relations with Armenia over its refusal to acknowledge the Armenian Genocide. Turkey was one of the first countries to recognize the Republic of Armenia (the 3rd republic) after its independence from the USSR in 1991. Despite this, for most of the 20th century and early 21st century, relations remain tense and there are no formal diplomatic relations between the two countries due to Turkey's refusal to establish them for numerous reasons. During the Nagorno-Karabakh War and citing it as the reason, Turkey illegally closed its land border with Armenia in 1993. It has not lifted its blockade despite pressure from the powerful Turkish business lobby interested in Armenian markets.

When did Armenia gain independence from the USSR?
Output: 1991

Input: Financial crisis of 2007%E2%80%9308
A 2000 United States Department of the Treasury study of lending trends for 305 cities from 1993 to 1998 showed that $467 billion of mortgage lending was made by Community Reinvestment Act (CRA)-covered lenders into low and mid level income (LMI) borrowers and neighborhoods, representing 10% of all U.S. mortgage lending during the period. The majority of these were prime loans. Sub-prime loans made by CRA-covered institutions constituted a 3% market share of LMI loans in 1998, but in the run-up to the crisis, fully 25% of all sub-prime lending occurred at CRA-covered institutions and another 25% of sub-prime loans had some connection with CRA. In addition, an analysis by the Federal Reserve Bank of Dallas in 2009, however, concluded that the CRA was not responsible for the mortgage loan crisis, pointing out that CRA rules have been in place since 1995 whereas the poor lending emerged only a decade later. Furthermore, most sub-prime loans were not made to the LMI borrowers targeted by the CRA, especially in the years 2005–2006 leading up to the crisis. Nor did it find any evidence that lending under the CRA rules increased delinquency rates or that the CRA indirectly influenced independent mortgage lenders to ramp up sub-prime lending.

What percent of sub-prime loans had some connection with CRA in the run-up to the financial crisis?
Output: 25%

Input: Botany
Epigenetic changes in eukaryotic biology serve to regulate the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. A single fertilized egg cell, the zygote, gives rise to the many different plant cell types including parenchyma, xylem vessel elements, phloem sieve tubes, guard cells of the epidermis, etc. as it continues to divide. The process results from the epigenetic activation of some genes and inhibition of others.

What process causes changes in plant cells?
Output:
Epigenetic changes
