(in the United States and Ireland, college is often used instead: "When I was in college..."). In Australia, Canada, New Zealand, the United Kingdom, Nigeria, the Netherlands, Spain and the German-speaking countries university is often contracted to uni. In Ghana, New Zealand and in South Africa it is sometimes called "varsity" (although this has become uncommon in New Zealand in recent years).

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.
What was the population of El Salvador in 1990?
A: unanswerable

Many assembled PCBs are static sensitive, and therefore must be placed in antistatic bags during transport. When handling these boards, the user must be grounded (earthed). Improper handling techniques might transmit an accumulated static charge through the board, damaging or destroying components. Even bare boards are sometimes static sensitive. Traces have become so fine that it's quite possible to blow an etch off the board (or change its characteristics) with a static charge. This is especially true on non-traditional PCBs such as MCMs and microwave PCBs.
Many assembled PABs are sensitive to what?
A:
unanswerable
