Teacher: This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: The French and Indian War (17541763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict. Question: When was the French and Indian War?
Solution: 1754-1763
Reason: It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. We can observe a similar notation from the passage to conclude that the French and Indian War happened during 17541763. Therefore, the answer is 17541763.

Now, solve this instance: Passage: The American observer Ingersoll reported at this time that "as to the accuracy of the bombing of military objectives, here I make no qualifications. The aim is surprisingly, astonishingly, amazingly inaccurate ... The physical damage to civilian London, to sum up, was more general and more extensive than I had imagined. The damage to military targets much less", and stated that he had seen numerous examples of untouched targets surrounded by buildings destroyed by errant bombs. For example, in two months of bombing, Battersea Power Station, perhaps the largest single target in London, had only received one minor hit ("a nick"). No bridge over the Thames had been hit, and the docks were still functioning despite great damage. An airfield was hit 56 times but the runways were never damaged and the field was never out of operation, despite German pilots' familiarity with it from prewar commercial flights. Ingersoll wrote that the difference between the failure of the German campaign against military targets versus its success in continental Europe was the RAF retaining control of the air.:7980,174 Question: The Battersea Power Station took how many hits in two months?
Student:
one minor hit ("a nick")
