Input: Read this: In the aftermath of the 1986 U.S. attack, the army was purged of perceived disloyal elements, and in 1988, Gaddafi announced the creation of a popular militia to replace the army and police. In 1987, Libya began production of mustard gas at a facility in Rabta, although publicly denying it was stockpiling chemical weapons, and unsuccessfully attempted to develop nuclear weapons. The period also saw a growth in domestic Islamist opposition, formulated into groups like the Muslim Brotherhood and the Libyan Islamic Fighting Group. A number of assassination attempts against Gaddafi were foiled, and in turn, 1989 saw the security forces raid mosques believed to be centres of counter-revolutionary preaching. In October 1993, elements of the increasingly marginalised army initiated a failed coup in Misrata, while in September 1995, Islamists launched an insurgency in Benghazi, and in July 1996 an anti-Gaddafist football riot broke out in Tripoli. The Revolutionary Committees experienced a resurgence to combat these Islamists.
Question: Where did Libya manufacture mustard gas?

Output: Rabta


Input: Read this: According to historian Shaye J. D. Cohen, the status of the offspring of mixed marriages was determined patrilineally in the Bible. He brings two likely explanations for the change in Mishnaic times: first, the Mishnah may have been applying the same logic to mixed marriages as it had applied to other mixtures (Kil'ayim). Thus, a mixed marriage is forbidden as is the union of a horse and a donkey, and in both unions the offspring are judged matrilineally. Second, the Tannaim may have been influenced by Roman law, which dictated that when a parent could not contract a legal marriage, offspring would follow the mother.
Question: What is one explanation for the change in Mishnaic times?

Output: the Mishnah may have been applying the same logic to mixed marriages as it had applied to other mixtures


Input: Read this: One advantage of the black box technique is that no programming knowledge is required. Whatever biases the programmers may have had, the tester likely has a different set and may emphasize different areas of functionality. On the other hand, black-box testing has been said to be "like a walk in a dark labyrinth without a flashlight." Because they do not examine the source code, there are situations when a tester writes many test cases to check something that could have been tested by only one test case, or leaves some parts of the program untested.
Question: Black-box coding has been compared to what?

Output: unanswerable


Input: Read this: The standing wave forms with this desired pattern at the design frequency, f0, and antennas are normally designed to be this size. However, feeding that element with 3f0 (whose wavelength is 1⁄3 that of f0) will also lead to a standing wave pattern. Thus, an antenna element is also resonant when its length is 3⁄4 of a wavelength. This is true for all odd multiples of 1⁄4 wavelength. This allows some flexibility of design in terms of antenna lengths and feed points. Antennas used in such a fashion are known to be harmonically operated.
Question: What frequency are antennas normally designed to be?

Output:
f0
