This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Passage: Despite yet another offer from the Institute for Advanced Study, Feynman rejected the Institute on the grounds that there were no teaching duties: Feynman felt that students were a source of inspiration and teaching was a diversion during uncreative spells. Because of this, the Institute for Advanced Study and Princeton University jointly offered him a package whereby he could teach at the university and also be at the institute.[citation needed] Feynman instead accepted an offer from the California Institute of Technology (Caltech)and as he says in his book Surely You're Joking Mr. Feynman!because a desire to live in a mild climate had firmly fixed itself in his mind while he was installing tire chains on his car in the middle of a snowstorm in Ithaca.
Why did Feynman decide to accept all offers from the Institute of Advanced Study?

Passage: Some opponents further claim that affirmative action has undesirable side-effects and that it fails to achieve its goals. They argue that it hinders reconciliation, replaces old wrongs with new wrongs, undermines the achievements of minorities, and encourages groups to identify themselves as disadvantaged, even if they are not. It may increase racial tension and benefit the more privileged people within minority groups at the expense of the disenfranchised within better-off groups (such as lower-class whites and Asians).There has recently been a strong push among American states to ban racial or gender preferences in university admissions, in reaction to the controversial and unprecedented decision in Grutter v. Bollinger. In 2006, nearly 60% of Michigan voters decided to ban affirmative action in university admissions. Michigan joined California, Florida, Texas, and Washington in banning the use of race or sex in admissions considerations. Some opponents believe, among other things, that affirmative action devalues the accomplishments of people who belong to a group it's supposed to help, therefore making affirmative action counter-productive. Furthermore, opponents of affirmative action claim that these policies dehumanize individuals and applicants to jobs or school are judged as members of a group without consideration for the individual person.
Other than failing to achieve its goal, what else do people who agree with affirmative action claim it has?

Passage: In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
Who led the congressional passages?
