Input: Read this: The city's largest private school by number of students is Temple University, followed by Drexel University. Along with the University of Pennsylvania, Temple University and Drexel University make up the city's major research universities. The city is also home to five schools of medicine: Drexel University College of Medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia College of Osteopathic Medicine, Temple University School of Medicine, and the Thomas Jefferson University. Hospitals, universities, and higher education research institutions in Philadelphia's four congressional districts received more than $252 million in National Institutes of Health grants in 2015.
Question: How many med schools are there?

Output: five

Input: Read this: In philosophy, emotions are studied in sub-fields such as ethics, the philosophy of art (for example, sensoryemotional values, and matters of taste and sentimentality), and the philosophy of music (see also Music and emotion). In history, scholars examine documents and other sources to interpret and analyze past activities; speculation on the emotional state of the authors of historical documents is one of the tools of interpretation. In literature and film-making, the expression of emotion is the cornerstone of genres such as drama, melodrama, and romance. In communication studies, scholars study the role that emotion plays in the dissemination of ideas and messages. Emotion is also studied in non-human animals in ethology, a branch of zoology which focuses on the scientific study of animal behavior. Ethology is a combination of laboratory and field science, with strong ties to ecology and evolution. Ethologists often study one type of behavior (for example, aggression) in a number of unrelated animals.
Question: Of what discipline is ethology a branch?

Output: zoology

Input: Read this: The coastline of Norfolk Island consists, to varying degrees, of cliff faces. A downward slope exists towards Slaughter Bay and Emily Bay, the site of the original colonial settlement of Kingston. There are no safe harbour facilities on Norfolk Island, with loading jetties existing at Kingston and Cascade Bay. All goods not domestically produced are brought in by ship, usually to Cascade Bay. Emily Bay, protected from the Pacific Ocean by a small coral reef, is the only safe area for recreational swimming, although surfing waves can be found at Anson and Ball Bays.
Question: Where are imported goods usually stolen on Norfolk Island?

Output: unanswerable

Input: Read this: FETs are further divided into depletion-mode and enhancement-mode types, depending on whether the channel is turned on or off with zero gate-to-source voltage. For enhancement mode, the channel is off at zero bias, and a gate potential can "enhance" the conduction. For the depletion mode, the channel is on at zero bias, and a gate potential (of the opposite polarity) can "deplete" the channel, reducing conduction. For either mode, a more positive gate voltage corresponds to a higher current for n-channel devices and a lower current for p-channel devices. Nearly all JFETs are depletion-mode because the diode junctions would forward bias and conduct if they were enhancement-mode devices; most IGFETs are enhancement-mode types.
Question: How are FET's separated?

Output:
depletion-mode and enhancement-mode types
