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.

Ex Input:
Passage: In countries such as China and Vietnam, the transition to a market economy has been a major factor in a move toward the rule of law, because a rule of law is important to foreign investors and to economic development. It remains unclear whether the rule of law in countries like China and Vietnam will be limited to commercial matters or will spill into other areas as well, and if so whether that spillover will enhance prospects for related values such as democracy and human rights. The rule of law in China has been widely discussed and debated by both legal scholars and politicians in China.

Ex Output:
What type of economy has rule of law help China and Vietnam move towards?


Ex Input:
Passage: The Standard Model groups matter particles into three generations, where each generation consists of two quarks and two leptons. The first generation is the up and down quarks, the electron and the electron neutrino; the second includes the charm and strange quarks, the muon and the muon neutrino; the third generation consists of the top and bottom quarks and the tau and tau neutrino. The most natural explanation for this would be that quarks and leptons of higher generations are excited states of the first generations. If this turns out to be the case, it would imply that quarks and leptons are composite particles, rather than elementary particles.

Ex Output:
What model has two generations?


Ex Input:
Passage: The materialist view is perhaps best understood in its opposition to the doctrines of immaterial substance applied to the mind historically, famously by René Descartes. However, by itself materialism says nothing about how material substance should be characterized. In practice, it is frequently assimilated to one variety of physicalism or another.

Ex Output:

Why was René Descartes declared a materialist?
