Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Between April 1877 and February 1878, she threatened five times to abdicate while pressuring Disraeli to act against Russia during the Russo-Turkish War, but her threats had no impact on the events or their conclusion with the Congress of Berlin. Disraeli's expansionist foreign policy, which Victoria endorsed, led to conflicts such as the Anglo-Zulu War and the Second Anglo-Afghan War. "If we are to maintain our position as a first-rate Power", she wrote, "we must ... be Prepared for attacks and wars, somewhere or other, CONTINUALLY." Victoria saw the expansion of the British Empire as civilising and benign, protecting native peoples from more aggressive powers or cruel rulers: "It is not in our custom to annexe countries", she said, "unless we are obliged & forced to do so." To Victoria's dismay, Disraeli lost the 1880 general election, and Gladstone returned as prime minister. When Disraeli died the following year, she was blinded by "fast falling tears", and erected a memorial tablet "placed by his grateful Sovereign and Friend, Victoria R.I."
To whom did Queen Victoria dedicate a memorial after his death for grateful service? 
A: Disraeli


Context and question: North Carolina was hard hit by the Great Depression, but the New Deal programs of Franklin D. Roosevelt for cotton and tobacco significantly helped the farmers. After World War II, the state's economy grew rapidly, highlighted by the growth of such cities as Charlotte, Raleigh, and Durham in the Piedmont. Raleigh, Durham, and Chapel Hill form the Research Triangle, a major area of universities and advanced scientific and technical research. In the 1990s, Charlotte became a major regional and national banking center. Tourism has also been a boon for the North Carolina economy as people flock to the Outer Banks coastal area and the Appalachian Mountains anchored by Asheville.
What programs created by FDR helped North Carolina during the Great Depression?
Answer: New Deal programs


Question: True exhibition games between opposing colleges at the highest level do not exist in college football; due to the importance of opinion polling in the top level of college football, even exhibition games would not truly be exhibitions because they could influence the opinions of those polled. Intramural games are possible because a team playing against itself leaves little ability for poll participants to make judgments, and at levels below the Football Bowl Subdivision (FBS), championships are decided by objective formulas and thus those teams can play non-league games without affecting their playoff hopes.
Is there an answer to this question: What consideration is more important for college teams than exhibition games?

Answer: opinion polling


Question: Domestication of sheep and goats reached Egypt from the Near East possibly as early as 6,000 BC. Graeme Barker states "The first indisputable evidence for domestic plants and animals in the Nile valley is not until the early fifth millennium bc in northern Egypt and a thousand years later further south, in both cases as part of strategies that still relied heavily on fishing, hunting, and the gathering of wild plants" and suggests that these subsistence changes were not due to farmers migrating from the Near East but was an indigenous development, with cereals either indigenous or obtained through exchange. Other scholars argue that the primary stimulus for agriculture and domesticated animals (as well as mud-brick architecture and other Neolithic cultural features) in Egypt was from the Middle East.
Is there an answer to this question: What region do some scholars see as the source for Egypt's start in agriculture?

Answer:
the Middle East
