Input: Read this: In the north, substantial efforts were made against Newcastle-upon-Tyne and Sunderland, which were large ports on the English east coast. On 9 April 1941 Luftflotte 2 dropped 150 tons of high explosives and 50,000 incendiaries from 120 bombers in a five-hour attack. Sewer, rail, docklands, and electric installations were damaged. In Sunderland on 25 April, Luftflotte 2 sent 60 bombers which dropped 80 tons of high explosive and 9,000 incendiaries. Much damage was done. A further attack on the Clyde, this time at Greenock, took place on 6 and 7 May. However, as with the attacks in the south, the Germans failed to prevent maritime movements or cripple industry in the regions.
Question: Sunderland saw how many incendiaries used against it on 25 April?

Output: 9,000 incendiaries

Input: Read this: The change is evident in the reports of influential British travellers to the Balkans. In 1894, Sir Henry Norman, 1st Baronet, a journalist, travelled to the Far East, afterwards writing a book called The Peoples and Politics of the Far East, which came out in 1895. By "Far East" he meant Siberia, China, Japan, Korea, Siam and Malaya. As the book was a big success, he was off to the Balkan states with his wife in 1896 to develop detail for a sequel, The People and Politics of the Near East, which Scribners planned to publish in 1897. Mrs. Norman, a writer herself, wrote glowing letters of the home and person of Mme. Zakki, "the wife of a Turkish cabinet minister," who, she said, was a cultivated woman living in a country home full of books. As for the natives of the Balkans, they were "a semi-civilized people."
Question: What book did Sir Henry Norman write after traveling to the Far East?

Output: The Peoples and Politics of the Far East

Input: Read this: The broad field of animal communication encompasses most of the issues in ethology. Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoo semiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized. A special field of animal communication has been investigated in more detail such as vibrational communication.
Question: Human and animal communication is a rapidly growing field of study in what century.

Output: unanswerable

Input: Read this: The ordinary half-wave dipole is probably the most widely used antenna design. This consists of two 14-wavelength elements arranged end-to-end, and lying along essentially the same axis (or collinear), each feeding one side of a two-conductor transmission wire. The physical arrangement of the two elements places them 180 degrees out of phase, which means that at any given instant one of the elements is driving current into the transmission line while the other is pulling it out. The monopole antenna is essentially one half of the half-wave dipole, a single 14-wavelength element with the other side connected to ground or an equivalent ground plane (or counterpoise). Monopoles, which are one-half the size of a dipole, are common for long-wavelength radio signals where a dipole would be impractically large. Another common design is the folded dipole, which is essentially two dipoles placed side-by-side and connected at their ends to make a single one-wavelength antenna.
Question: Elements in a half wave dipole and on an identical axis are said to be what?

Output:
collinear
