Problem: Spanish language in the United States:

As civil wars engulfed several Central American countries in the 1980s, hundreds of thousands of Salvadorans fled their country and came to the United States. Between 1980 and 1990, the Salvadoran immigrant population in the United States increased nearly fivefold from 94,000 to 465,000. The number of Salvadoran immigrants in the United States continued to grow in the 1990s and 2000s as a result of family reunification and new arrivals fleeing a series of natural disasters that hit El Salvador, including earthquakes and hurricanes. By 2008, there were about 1.1 million Salvadoran immigrants in the United States.

Why did Central Americans flee to the U.S.?

A: civil wars engulfed several Central American countries in the 1980s


Problem: There are over three thousand islands along the rugged coastline of Zhejiang. The largest, Zhoushan Island, is Mainland China's third largest island, after Hainan and Chongming. There are also many bays, of which Hangzhou Bay is the largest.  Zhejiang has a humid subtropical climate with four distinct seasons. Spring starts in March and is rainy with changeable weather. Summer, from June to September is long, hot, rainy, and humid. Fall is generally dry, warm and sunny. Winters are short but cold except in the far south. Average annual temperature is around 15 to 19 °C (59 to 66 °F), average January temperature is around 2 to 8 °C (36 to 46 °F) and average July temperature is around 27 to 30 °C (81 to 86 °F). Annual precipitation is about 1,000 to 1,900 mm (39 to 75 in). There is plenty of rainfall in early summer, and by late summer Zhejiang is directly threatened by typhoons forming in the Pacific.
When does Spring start in Zhejiang?

Answer: March

Context and question: Within computer systems, two of many security models capable of enforcing privilege separation are access control lists (ACLs) and capability-based security. Using ACLs to confine programs has been proven to be insecure in many situations, such as if the host computer can be tricked into indirectly allowing restricted file access, an issue known as the confused deputy problem. It has also been shown that the promise of ACLs of giving access to an object to only one person can never be guaranteed in practice. Both of these problems are resolved by capabilities. This does not mean practical flaws exist in all ACL-based systems, but only that the designers of certain utilities must take responsibility to ensure that they do not introduce flaws.[citation needed]
ACLs and capability based security are two security models capable of what?
Answer: enforcing privilege separation


Question: The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.
Is there an answer to this question: What is the purpose of the gas in a light bulb?

Answer: to prevent evaporation of the filament, without introducing significant heat losses
