QUES: Supercomputers in particular often have highly unique architectures that differ significantly from the basic stored-program architecture and from general purpose computers. They often feature thousands of CPUs, customized high-speed interconnects, and specialized computing hardware. Such designs tend to be useful only for specialized tasks due to the large scale of program organization required to successfully utilize most of the available resources at once. Supercomputers usually see usage in large-scale simulation, graphics rendering, and cryptography applications, as well as with other so-called "embarrassingly parallel" tasks.
How many CPUs do supercomputers typically possess?

ANS: thousands

QUES: In the US, African Americans, who include multiracial people, earn 75% of what white people earn. In Brazil, people of color earn less than 50% of what whites earn. Some have posited that the facts of lower socioeconomic status for people of color suggest that Brazil practices a kind of one-drop rule, or discrimination against people who are not visibly European in ancestry. The gap in income between blacks and other non-whites is relatively small compared to the large gap between whites and all people of color. Other social factors, such as illiteracy and education levels, show the same patterns of disadvantage for people of color. Some commentators observe that the United States practice of segregation and white supremacy in the South, and discrimination in many areas outside that region, forced many African Americans to unite in the civil rights struggle. They suggest that the fluid nature of race in Brazil has divided individuals of African descent, between those with more or less ancestry. As a result, they have not united for a stronger civil rights movement.[citation needed]
What other patterns are consistent with unequal living standards?

ANS: illiteracy and education levels

QUES: The Laurentian Highlands, the Interior Plains and the Interior Highlands lie between the two coasts, stretching from the Gulf of Mexico northward, far beyond the national boundary, to the Arctic Ocean. The central plains are divided by a hardly perceptible height of land into a Canadian and a United States portion. It is from the United States side, that the great Mississippi system discharges southward to the Gulf of Mexico. The upper Mississippi and some of the Ohio basin is the semi-arid prairie region, with trees originally only along the watercourses. The uplands towards the Appalachians were included in the great eastern forested area, while the western part of the plains has so dry a climate that its native plant life is scanty, and in the south it is practically barren.
What is the name of the three highlands that stretched from the Gulf of Mexico to the Arctic Ocean?

ANS: unanswerable

QUES: In 1870, following the stunning defeat of the French Army by the Germans in the Franco-Prussian War, French workers and socialist revolutionaries seized Paris and created the Paris Commune. The Commune lasted for two months before it was crushed by the French Army, with much bloodshed. The original red banners of the Commune became icons of the socialist revolution; in 1921 members of the French Communist Party came to Moscow and presented the new Soviet government with one of the original Commune banners; it was placed (and is still in place) in the tomb of Vladimir Lenin, next to his open coffin.
For how long did the Paris Commune exist?

ANS:
two months
