Input: Read this: Political color schemes in the United States diverge from international norms. Since 2000, red has become associated with the right-wing Republican Party and blue with the left-wing Democratic Party. However, unlike political color schemes of other countries, the parties did not choose those colors; they were used in news coverage of 2000 election results and ensuing legal battle and caught on in popular usage. Prior to the 2000 election the media typically alternated which color represented which party each presidential election cycle. The color scheme happened to get inordinate attention that year, so the cycle was stopped lest it cause confusion the following election.
Question: What happened when other countries violated political color scheme norms in 2000?

Output: unanswerable


QUES: The James River reaches tidewater at Richmond where flooding may occur in every month of the year, most frequently in March and least in July. Hurricanes and tropical storms have been responsible for most of the flooding during the summer and early fall months. Hurricanes passing near Richmond have produced record rainfalls. In 1955, three hurricanes brought record rainfall to Richmond within a six-week period. The most noteworthy of these were Hurricane Connie and Hurricane Diane that brought heavy rains five days apart. And in 2004, the downtown area suffered extensive flood damage after the remnants of Hurricane Gaston dumped up to 12 inches (300 mm) of rainfall.

In 1955, Richmond was hit with three hurricanes in how many weeks?
What is the answer?
ANS: six


QUES: As the 10th century progressed, the Khazars were no longer able to command tribute from the Volga Bulgars, and their relationship with the Byzantines deteriorated, as Byzantium increasingly allied with the Pechenegs against them. The Pechenegs were thus secure to raid the lands of the Khazars from their base between the Volga and Don rivers, allowing them to expand to the west. Rus' relations with the Pechenegs were complex, as the groups alternately formed alliances with and against one another. The Pechenegs were nomads roaming the steppe raising livestock which they traded with the Rus' for agricultural goods and other products. The lucrative Rus' trade with the Byzantine Empire had to pass through Pecheneg-controlled territory, so the need for generally peaceful relations was essential. Nevertheless, while the Primary Chronicle reports the Pechenegs entering Rus' territory in 915 and then making peace, they were waging war with one another again in 920. Pechenegs are reported assisting the Rus' in later campaigns against the Byzantines, yet allied with the Byzantines against the Rus' at other times.
Whose relationship with Khazars improved?

ANS: unanswerable


Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:

Input: Read this: The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.
Question: What brought up enhancement of drug regulations?

Output:
The thalidomide tragedy
