In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
What are lifts?, Context: Stage lifts and orchestra lifts are specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage. For example, Radio City Music Hall has four such elevators: an orchestra lift that covers a large area of the stage, and three smaller lifts near the rear of the stage. In this case, the orchestra lift is powerful enough to raise an entire orchestra, or an entire cast of performers (including live elephants) up to stage level from below. There's a barrel on the background of the image of the left which can be used as a scale to represent the size of the mechanism

Ex Output:
specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage


Ex Input:
What is the parent agency for the Center for Drug Evaluation and Research?, Context: Possible improvements include clarification of clinical trial regulations by FDA. Furthermore, appropriate economic incentives could persuade pharmaceutical companies to invest in this endeavor. Antibiotic Development to Advance Patient Treatment (ADAPT) Act aims to fast track the drug development to combat the growing threat of 'superbugs'. Under this Act, FDA can approve antibiotics and antifungals treating life-threatening infections based on smaller clinical trials. The CDC will monitor the use of antibiotics and the emerging resistance, and publish the data. The FDA antibiotics labeling process, 'Susceptibility Test Interpretive Criteria for Microbial Organisms' or 'breakpoints', will provide accurate data to healthcare professionals. According to Allan Coukell, senior director for health programs at The Pew Charitable Trusts, "By allowing drug developers to rely on smaller datasets, and clarifying FDA's authority to tolerate a higher level of uncertainty for these drugs when making a risk/benefit calculation, ADAPT would make the clinical trials more feasible."

Ex Output:
FDA


Ex Input:
If you were to go and visit a site of historical significance, where might you go?, Context: Egypt also hosts an unknown number of refugees and asylum seekers, estimated to be between 500,000 and 3 million. There are some 70,000 Palestinian refugees, and about 150,000 recently arrived Iraqi refugees, but the number of the largest group, the Sudanese, is contested.[nb 1] The once-vibrant and ancient Greek and Jewish communities in Egypt have almost disappeared, with only a small number remaining in the country, but many Egyptian Jews visit on religious or other occasions and tourism. Several important Jewish archaeological and historical sites are found in Cairo, Alexandria and other cities.
