Article: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.

Question: What contributes to the Antarctic cold?
Ans: orbital distance


Here is a question about this article: Knots do not necessarily influence the stiffness of structural timber, this will depend on the size and location. Stiffness and elastic strength are more dependent upon the sound wood than upon localized defects. The breaking strength is very susceptible to defects. Sound knots do not weaken wood when subject to compression parallel to the grain.
What is the answer to this question: What do stiffness and elastic strength depend on more than defects?
****
So... sound wood


The problem: Answer a question about this article:
The American people are mostly multi-ethnic descendants of various culturally distinct immigrant groups, many of which have now developed nations. Some consider themselves multiracial, while acknowledging race as a social construct. Creolization, assimilation and integration have been continuing processes. The African-American Civil Rights Movement (1955–1968) and other social movements since the mid-twentieth century worked to achieve social justice and equal enforcement of civil rights under the constitution for all ethnicities. In the 2000s, less than 5% of the population identified as multiracial. In many instances, mixed racial ancestry is so far back in an individual's family history (for instance, before the Civil War or earlier), that it does not affect more recent ethnic and cultural identification.
How much of the population identified as mixed race in the 2000s?
****
The answer: less than 5%


Problem: Please answer a question about the following article about Computer:
In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. The effort was funded by ARPA (now DARPA), and the computer network that resulted was called the ARPANET. The technologies that made the Arpanet possible spread and evolved.
ARPA is now known as what?
A: DARPA)


Question: Read this and answer the question

Short-term memory is supported by transient patterns of neuronal communication, dependent on regions of the frontal lobe (especially dorsolateral prefrontal cortex) and the parietal lobe. Long-term memory, on the other hand, is maintained by more stable and permanent changes in neural connections widely spread throughout the brain. The hippocampus is essential (for learning new information) to the consolidation of information from short-term to long-term memory, although it does not seem to store information itself. Without the hippocampus, new memories are unable to be stored into long-term memory, as learned from patient Henry Molaison after removal of both his hippocampi, and there will be a very short attention span. Furthermore, it may be involved in changing neural connections for a period of three months or more after the initial learning.

How much information can the hippocampus store?
Answer: does not


Following the Protestant Reformation, promoted by local reformer Martin Bucer, the principle of cuius regio, eius religio led to a certain amount of religious diversity in the highlands of northern Alsace. Landowners, who as "local lords" had the right to decide which religion was allowed on their land, were eager to entice populations from the more attractive lowlands to settle and develop their property. Many accepted without discrimination Catholics, Lutherans, Calvinists, Jews and Anabaptists. Multiconfessional villages appeared, particularly in the region of Alsace bossue. Alsace became one of the French regions boasting a thriving Jewish community, and the only region with a noticeable Anabaptist population. The schism of the Amish under the lead of Jacob Amman from the Mennonites occurred in 1693 in Sainte-Marie-aux-Mines. The strongly Catholic Louis XIV tried in vain to drive them from Alsace. When Napoleon imposed military conscription without religious exception, most emigrated to the American continent.
Which groups or religions were greatly accepted in Alsace?
Catholics, Lutherans, Calvinists, Jews and Anabaptists
