Input: Transistor
Providing sufficient base drive current is a key problem in the use of bipolar transistors as switches. The transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal. The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current. In the example light-switch circuit shown, the resistor is chosen to provide enough base current to ensure the transistor will be saturated.

If the type of transistor is the same what determines the current ratio?
Output: collector current


Input: Article: As noted in the introduction to this article, the American public has maintained its position of support for capital punishment for murder. However, when given a choice between the death penalty and life imprisonment without parole, support has traditionally been significantly lower than polling which has only mentioned the death penalty as a punishment. In 2010, for instance, one poll showed 49 percent favoring the death penalty and 46 percent favoring life imprisonment while in another 61% said they preferred another punishment to the death penalty. The highest level of support for the death penalty recorded overall was 80 percent in 1994 (16 percent opposed), and the lowest recorded was 42 percent in 1966 (47 percent opposed). On the question of the death penalty vs. life without parole, the strongest preference for the death penalty was 61 percent in 1997 (29 percent favoring life), and the lowest preference for the death penalty was 47 percent in 2006 (48 percent favoring life).

Now answer this question: In a 2006 poll, what percentage of polled Americans preferred the death penalty to life without parole?

Output: 47

The problem: Answer a question about this article:
The colloquialism "buck"(s) (much like the British word "quid"(s, pl) for the pound sterling) is often used to refer to dollars of various nations, including the U.S. dollar. This term, dating to the 18th century, may have originated with the colonial leather trade. It may also have originated from a poker term. "Greenback" is another nickname originally applied specifically to the 19th century Demand Note dollars created by Abraham Lincoln to finance the costs of the Civil War for the North. The original note was printed in black and green on the back side. It is still used to refer to the U.S. dollar (but not to the dollars of other countries). Other well-known names of the dollar as a whole in denominations include "greenmail", "green" and "dead presidents" (the last because deceased presidents are pictured on most bills).
What kind of trade may have been the origin of the "buck"?
****
The answer:
colonial leather trade
