Input: Airport
Most major airports provide commercial outlets for products and services. Most of these companies, many of which are internationally known brands, are located within the departure areas. These include clothing boutiques and restaurants. Prices charged for items sold at these outlets are generally higher than those outside the airport. However, some airports now regulate costs to keep them comparable to "street prices". This term is misleading as prices often match the manufacturers' suggested retail price (MSRP) but are almost never discounted.[citation needed]

Most major airports provide commercial outlets for what?
Output: products and services

Article: On 12 February 1912, after rounds of negotiations, Longyu issued an imperial edict bringing about the abdication of the child emperor Puyi. This brought an end to over 2,000 years of Imperial China and began an extended period of instability of warlord factionalism. The unorganized political and economic systems combined with a widespread criticism of Chinese culture led to questioning and doubt about the future. In the 1930s, the Empire of Japan invaded Northeast China and founded Manchukuo in 1932, with Puyi, as the emperor. After the invasion by the Soviet Union, Manchukuo collapsed in 1945.

Question: What year did the end of Imperial China occur?
Ans: 1912

The problem: Answer a question about this article:
Motors have very little room for electrical insulation so they generally have low voltage ratings. Because transformers (prior to the development of power electronics) cannot step down DC voltages, trains were supplied with a relatively low DC voltage that the motors can use directly. The most common DC voltages are listed in the previous section. Third (and fourth) rail systems almost always use voltages below 1 kV for safety reasons while overhead wires usually use higher voltages for efficiency. ("Low" voltage is relative; even 600 V can be instantly lethal when touched.)
Is "low" voltage used by trains safe for people?
****
The answer:
lethal
