TASK DEFINITION: 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.
PROBLEM: Passage: 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.

SOLUTION: What is always possible to do?

PROBLEM: Passage: Comcast is sometimes described as a family business. Brian L. Roberts, Chairman, President, and CEO of Comcast, is son of co-founder Ralph Roberts. Roberts owns or controls just over 1% of all Comcast shares but all of the Class B supervoting shares, which gives him an "undilutable 33% voting power over the company". Legal expert Susan P. Crawford has said this gives him "effective control over its [Comcast's] every step". In 2010, he was one of the highest-paid executives in the United States, with total compensation of about $31 million.

SOLUTION: Who is Brian L. Robert's son?

PROBLEM: Passage: Economic reform efforts continued with the support of international organizations, notably the World Bank and the International Monetary Fund. The reform program came to a halt in June 1997 when civil war erupted. When Sassou Nguesso returned to power at the end of the war in October 1997, he publicly expressed interest in moving forward on economic reforms and privatization and in renewing cooperation with international financial institutions. However, economic progress was badly hurt by slumping oil prices and the resumption of armed conflict in December 1998, which worsened the republic's budget deficit.

SOLUTION:
What organization never supported economic reform efforts?
