The problem: Answer a question about this article:
Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.
What term can be used to refer to the usable spectrum of an antennas frequency?
****
The answer: bandwidth

Translation of a text that is sung in vocal music for the purpose of singing in another languagesometimes called "singing translation"is closely linked to translation of poetry because most vocal music, at least in the Western tradition, is set to verse, especially verse in regular patterns with rhyme. (Since the late 19th century, musical setting of prose and free verse has also been practiced in some art music, though popular music tends to remain conservative in its retention of stanzaic forms with or without refrains.) A rudimentary example of translating poetry for singing is church hymns, such as the German chorales translated into English by Catherine Winkworth.
What type of example an be found of translating poetry for singing?
****
The answer: church hymns

The problem: Answer a question about this article:
The question to be answered is whether a listed species will be harmed by the action and, if so, how the harm can be minimized. If harm cannot be avoided, the project agency can seek an exemption from the Endangered Species Committee, an ad hoc panel composed of members from the executive branch and at least one appointee from the state where the project is to occur. Five of the seven committee members must vote for the exemption to allow taking (to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or significant habitat modification, or to attempt to engage in any such conduct) of listed species.
What is the primary consideration for determining if projects may be carried out in areas with endangered species?
****
The answer: whether a listed species will be harmed by the action and, if so, how the harm can be minimized

The problem: Answer a question about this article:
On February 20, 1863, Kansas Governor Thomas Carney signed into law a bill creating the state university in Lawrence. The law was conditioned upon a gift from Lawrence of a $15,000 endowment fund and a site for the university, in or near the town, of not less than forty acres (16 ha) of land. If Lawrence failed to meet these conditions, Emporia instead of Lawrence would get the university.
How much money did Lawrence have to contribute to the University as terms of its charter?
****
The answer:
$15,000
