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.

Example Input: Passage: Following their basic and advanced training at the individual-level, soldiers may choose to continue their training and apply for an "additional skill identifier" (ASI). The ASI allows the army to take a wide ranging MOS and focus it into a more specific MOS. For example, a combat medic, whose duties are to provide pre-hospital emergency treatment, may receive ASI training to become a cardiovascular specialist, a dialysis specialist, or even a licensed practical nurse. For commissioned officers, ASI training includes pre-commissioning training either at USMA, or via ROTC, or by completing OCS. After commissioning, officers undergo branch specific training at the Basic Officer Leaders Course, (formerly called Officer Basic Course), which varies in time and location according their future assignments. Further career development is available through the Army Correspondence Course Program.
Example Output: What does ISI stand for?

Example Input: Passage: In Homer's Iliad, the names Danaans (or Danaoi: Δαναοί) and Argives (Argives: Αργείοι) are used to designate the Greek forces opposed to the Trojans. The myth of Danaus, whose origin is Egypt, is a foundation legend of Argos. His daughters Danaides, were forced in Tartarus to carry a jug to fill a bathtub without a bottom. This myth is connected with a task that can never be fulfilled (Sisyphos) and the name can be derived from the PIE root *danu: "river". There is not any satisfactory theory on their origin. Some scholars connect Danaans with the Denyen, one of the groups of the sea peoples who attacked Egypt during the reign of Ramesses III (1187-1156 BCE). The same inscription mentions the Weshesh who might have been the Achaeans. The Denyen seem to have been inhabitants of the city Adana in Cilicia. Pottery similar to that of Mycenae itself has been found in Tarsus of Cilicia and it seems that some refugees from the Aegean went there after the collapse of the Mycenean civilization. These Cilicians seem to have been called Dananiyim, the same word as Danaoi who attacked Egypt in 1191 BC along with the Quaouash (or Weshesh) who may be Achaeans. They were also called Danuna according to a Hittite inscription and the same name is mentioned in the Amarna letters. Julius Pokorny reconstructs the name from the PIE root da:-: "flow, river", da:-nu: "any moving liquid, drops", da: navo "people living by the river, Skyth. nomadic people (in Rigveda water-demons, fem.Da:nu primordial goddess), in Greek Danaoi, Egypt. Danuna". It is also possible that the name Danaans is pre-Greek. A country Danaja with a city Mukana (propaply: Mycenea) is mentioned in inscriptions from Egypt from Amenophis III (1390-1352 BC), Thutmosis III (1437 BC).
Example Output: In Homer's poems who were the Greeks not at odds with?

Example Input: Passage: The loss of eight battleships and 2,403 Americans at Pearl Harbor forced the U.S. to rely on its remaining aircraft carriers, which won a major victory over Japan at Midway just six months into the war, and on its growing submarine fleet. The Navy and Marine Corps followed this up with an island hopping campaign across the central and south Pacific in 1943–45, reaching the outskirts of Japan in the Battle of Okinawa. During 1942 and 1943, the U.S. deployed millions of men and thousands of planes and tanks to the UK, beginning with the strategic bombing of Nazi Germany and occupied Europe and leading up to the Allied invasions of occupied North Africa in November 1942, Sicily and Italy in 1943, France in 1944, and the invasion of Germany in 1945, parallel with the Soviet invasion from the east. That led to the surrender of Nazi Germany in May 1945. In the Pacific, the U.S. experienced much success in naval campaigns during 1944, but bloody battles at Iwo Jima and Okinawa in 1945 led the U.S. to look for a way to end the war with minimal loss of American lives. The U.S. used atomic bombs on Hiroshima and Nagasaki to destroy the Japanese war effort and to shock the Japanese leadership, which quickly caused the surrender of Japan.
Example Output:
How many battleships did the UK Navy lose at Pearl Harbor?
