Input: Alfred North Whitehead
The ultimate substantive legacy of Principia Mathematica is mixed. It is generally accepted that Kurt Gödel's incompleteness theorem of 1931 definitively demonstrated that for any set of axioms and inference rules proposed to encapsulate mathematics, there would in fact be some truths of mathematics which could not be deduced from them, and hence that Principia Mathematica could never achieve its aims. However, Gödel could not have come to this conclusion without Whitehead and Russell's book. In this way, Principia Mathematica's legacy might be described as its key role in disproving the possibility of achieving its own stated goals. But beyond this somewhat ironic legacy, the book popularized modern mathematical logic and drew important connections between logic, epistemology, and metaphysics.

Despite its imperfection, what are now considered valuable achievements of Principia Mathematica?
Output: the book popularized modern mathematical logic and drew important connections between logic, epistemology, and metaphysics

Input: Karl Popper
Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.

According to Popper, what resolves conflicting hypotheses and observations in the long run?
Output: the collective judgment of scientists

Input: FC Barcelona
Domestically, Barcelona has won 23 La Liga, 27 Copa del Rey, 11 Supercopa de España, 3 Copa Eva Duarte and 2 Copa de la Liga trophies, as well as being the record holder for the latter four competitions. In international club football, Barcelona has won five UEFA Champions League titles, a record four UEFA Cup Winners' Cup, a shared record five UEFA Super Cup, a record three Inter-Cities Fairs Cup and a record three FIFA Club World Cup trophies. Barcelona was ranked first in the IFFHS Club World Ranking for 1997, 2009, 2011, 2012 and 2015 and currently occupies the second position on the UEFA club rankings. The club has a long-standing rivalry with Real Madrid; matches between the two teams are referred to as El Clásico.

How many UEFA  Cup Winners' Cup wins does Barcelona have?
Output: four

Input: Buddhism
According to East Asian and Tibetan Buddhism, there is an intermediate state (Tibetan "bardo") between one life and the next. The orthodox Theravada position rejects this; however there are passages in the Samyutta Nikaya of the Pali Canon that seem to lend support to the idea that the Buddha taught of an intermediate stage between one life and the next.[page needed]

Some passages of what Canon support the idea of intermediate stages?
Output:
Pali
