Problem: Marvel Comics:

Lee and freelance artist and eventual co-plotter Jack Kirby's Fantastic Four originated in a Cold War culture that led their creators to revise the superhero conventions of previous eras to better reflect the psychological spirit of their age. Eschewing such comic-book tropes as secret identities and even costumes at first, having a monster as one of the heroes, and having its characters bicker and complain in what was later called a "superheroes in the real world" approach, the series represented a change that proved to be a great success.

What traditional superhero element did the Fantastic Four initially do without?
---
A: costumes


Problem: Columbia founded Epic Records in 1953. In 1956, Conkling left Columbia, he would help establish the National Academy of Recording Arts and Sciences before eventually becoming the first president of the newly launched Warner Bros. Records, and Goddard Lieberson began the first of two stints as head of the record company. In 1958, Columbia founded another label, Date Records, which initially issued rockabilly music.
Lieberson helped establish the National Academy of what?

Answer: unanswerable


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
To Popper, who was an anti-justificationist, traditional philosophy is misled by the false principle of sufficient reason. He thinks that no assumption can ever be or needs ever to be justified, so a lack of justification is not a justification for doubt. Instead, theories should be tested and scrutinised. It is not the goal to bless theories with claims of certainty or justification, but to eliminate errors in them. He writes, "there are no such things as good positive reasons; nor do we need such things [...] But [philosophers] obviously cannot quite bring [themselves] to believe that this is my opinion, let alone that it is right" (The Philosophy of Karl Popper, p. 1043)
Who believed that good positive reasons exist?
A: unanswerable


Context and question: These deities formed a core pantheon; there were additionally hundreds of minor ones. Sumerian gods could thus have associations with different cities, and their religious importance often waxed and waned with those cities' political power. The gods were said to have created human beings from clay for the purpose of serving them. The temples organized the mass labour projects needed for irrigation agriculture. Citizens had a labor duty to the temple, though they could avoid it by a payment of silver.
How could a citizen avoid their labor duty to their local temple?
Answer: a payment of silver


Question: A UCLA research study published in the June 2006 issue of the American Journal of Geriatric Psychiatry found that people can improve cognitive function and brain efficiency through simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives. This study examined 17 subjects, (average age 53) with normal memory performance. Eight subjects were asked to follow a "brain healthy" diet, relaxation, physical, and mental exercise (brain teasers and verbal memory training techniques). After 14 days, they showed greater word fluency (not memory) compared to their baseline performance. No long term follow up was conducted, it is therefore unclear if this intervention has lasting effects on memory.
Is there an answer to this question: Do lifestyle changes definitely have an affect on long term memory?

Answer: it is therefore unclear if this intervention has lasting effects on memory.


QUES: Von Neumann raised the intellectual and mathematical level of economics in several stunning publications. For his model of an expanding economy, von Neumann proved the existence and uniqueness of an equilibrium using his generalization of the Brouwer fixed-point theorem. Von Neumann's model of an expanding economy considered the matrix pencil  A − λB with nonnegative matrices A and B; von Neumann sought probability vectors p and q and a positive number λ that would solve the complementarity equation

What did von Neumann prove with his model of expanding economy?
What is the answer?
ANS:
uniqueness of an equilibrium using his generalization of the Brouwer fixed-point theorem
