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.

Input: Consider Input: Passage: Jews are often identified as belonging to one of two major groups: the Ashkenazim and the Sephardim. Ashkenazim, or "Germanics" (Ashkenaz meaning "Germany" in Hebrew), are so named denoting their German Jewish cultural and geographical origins, while Sephardim, or "Hispanics" (Sefarad meaning "Spain/Hispania" or "Iberia" in Hebrew), are so named denoting their Spanish/Portuguese Jewish cultural and geographic origins. The more common term in Israel for many of those broadly called Sephardim, is Mizrahim (lit. "Easterners", Mizrach being "East" in Hebrew), that is, in reference to the diverse collection of Middle Eastern and North African Jews who are often, as a group, referred to collectively as Sephardim (together with Sephardim proper) for liturgical reasons, although Mizrahi Jewish groups and Sephardi Jews proper are ethnically distinct.

Output: How many major groups do the Ashkenazim belong to?


Input: Consider Input: Passage: Since World War II, aircraft carrier designs have increased in size to accommodate a steady increase in aircraft size. The large, modern Nimitz class of US carriers has a displacement nearly four times that of the World War II–era USS Enterprise, yet its complement of aircraft is roughly the same—a consequence of the steadily increasing size and weight of military aircraft over the years. Today's aircraft carriers are so expensive that nations which operate them risk significant political, economic, and military impact if a carrier is lost, or even used in conflict.

Output: Why have aircraft carriers increased in size since World War I?


Input: Consider Input: Passage: Tuberculosis has been present in humans since antiquity. The earliest unambiguous detection of M. tuberculosis involves evidence of the disease in the remains of bison in Wyoming dated to around 17,000 years ago. However, whether tuberculosis originated in bovines, then was transferred to humans, or whether it diverged from a common ancestor, is currently unclear. A comparison of the genes of M. tuberculosis complex (MTBC) in humans to MTBC in animals suggests humans did not acquire MTBC from animals during animal domestication, as was previously believed. Both strains of the tuberculosis bacteria share a common ancestor, which could have infected humans as early as the Neolithic Revolution.


Output: When was Wyoming discovered?
