The problem: Answer a question about this article:
Mandolin has also been used in blues music, most notably by Ry Cooder, who performed outstanding covers on his very first recordings, Yank Rachell, Johnny "Man" Young, Carl Martin, and Gerry Hundt. Howard Armstrong, who is famous for blues violin, got his start with his father's mandolin and played in string bands similar to the other Tennessee string bands he came into contact with, with band makeup including "mandolins and fiddles and guitars and banjos. And once in a while they would ease a little ukulele in there and a bass fiddle." Other blues players from the era's string bands include Willie Black (Whistler And His Jug Band), Dink Brister, Jim Hill, Charles Johnson, Coley Jones (Dallas String Band), Bobby Leecan (Need More Band), Alfred Martin, Charlie McCoy (1909-1950), Al Miller, Matthew Prater, and Herb Quinn.
Who got his start with his father's mandolin?
****
The answer: Howard Armstrong,

Problem: Please answer a question about the following article about Black people:
In South Africa, the period of colonization resulted in many unions and marriages between European men and African women from various tribes, resulting in mixed-race children. As the Europeans acquired territory and imposed rule over the Africans, they generally pushed mixed-race and Africans into second-class status. During the first half of the 20th century, the Afrikaaner-dominated government classified the population according to four main racial groups: Black, White, Asian (mostly Indian), and Coloured. The Coloured group included people of mixed Bantu, Khoisan, and European descent (with some Malay ancestry, especially in the Western Cape). The Coloured definition occupied an intermediary political position between the Black and White definitions in South Africa. It imposed a system of legal racial segregation, a complex of laws known as apartheid.
What class were Africans and Mixed Race children considered?
A: second-class

Question: Read this and answer the question

When power is lost in a traction elevator system, all elevators will initially come to a halt. One by one, each car in the group will return to the lobby floor, open its doors and shut down. People in the remaining elevators may see an indicator light or hear a voice announcement informing them that the elevator will return to the lobby shortly. Once all cars have successfully returned, the system will then automatically select one or more cars to be used for normal operations and these cars will return to service. The car(s) selected to run under emergency power can be manually overridden by a key or strip switch in the lobby. In order to help prevent entrapment, when the system detects that it is running low on power, it will bring the running cars to the lobby or nearest floor, open the doors and shut down.

What sequence of events happens when the power shuts off in a traction elevator and the elevators all stop?
Answer: One by one, each car in the group will return to the lobby floor, open its doors and shut down

Problem: The first record of the name Israel (as ysrir) occurs in the Merneptah stele, erected for Egyptian Pharaoh Merneptah c. 1209 BCE, "Israel is laid waste and his seed is not." This "Israel" was a cultural and probably political entity of the central highlands, well enough established to be perceived by the Egyptians as a possible challenge to their hegemony, but an ethnic group rather than an organised state; Ancestors of the Israelites may have included Semites native to Canaan and the Sea Peoples. McNutt says, "It is probably safe to assume that sometime during Iron Age a population began to identify itself as 'Israelite'", differentiating itself from the Canaanites through such markers as the prohibition of intermarriage, an emphasis on family history and genealogy, and religion.
What did Canaanites prohibit?
The answer is the following: intermarriage

Historically, the paper was not overtly pro-Tory or Whig, but has been a long time bastion of the English Establishment and empire. The Times adopted a stance described as "peculiarly detached" at the 1945 general election; although it was increasingly critical of the Conservative Party's campaign, it did not advocate a vote for any one party. However, the newspaper reverted to the Tories for the next election five years later. It supported the Conservatives for the subsequent three elections, followed by support for both the Conservatives and the Liberal Party for the next five elections, expressly supporting a Con-Lib coalition in 1974. The paper then backed the Conservatives solidly until 1997, when it declined to make any party endorsement but supported individual (primarily Eurosceptic) candidates.
What kind of political coalition did The Times support in 1974?
Con-Lib coalition

Here is a question about this article: Two assumptions underpinned the British approach to HAA fire; first, aimed fire was the primary method and this was enabled by predicting gun data from visually tracking the target and having its height. Second, that the target would maintain a steady course, speed and height. This HAA was to engage targets up to 24,000 feet. Mechanical, as opposed to igniferous, time fuses were required because the speed of powder burning varied with height so fuse length was not a simple function of time of flight. Automated fire ensured a constant rate of fire that made it easier to predict where each shell should be individually aimed.
What is the answer to this question: Along with predicting the gun data from tracking the target, what else needed to be known about the target to enable the aimed fire?
****
So...
its height
