Problem: Pharmaceutical industry:

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.

What brought up enhancement of Congress regulations?

A: unanswerable


Problem: The Demilitarized Zone runs northeast of the 38th parallel; to the south, it travels west. The old Korean capital city of Kaesong, site of the armistice negotiations, originally was in pre-war South Korea, but now is part of North Korea. The United Nations Command, supported by the United States, the North Korean People's Army, and the Chinese People's Volunteers, signed the Armistice Agreement on 27 July 1953 to end the fighting. The Armistice also called upon the governments of South Korea, North Korea, China and the United States to participate in continued peace talks. The war is considered to have ended at this point, even though there was no peace treaty. North Korea nevertheless claims that it won the Korean War.
Where is the capital city of Kaesong now located?

Answer: North Korea


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the north Eristov pushed southwest, fought two battles, forced the Turks back to Batum, retired behind the Cholok River and suspended action for the rest of the year (June). In the far south Wrangel pushed west, fought a battle and occupied Bayazit. In the center the main forces stood at Kars and Gyumri. Both slowly approached along the Kars-Gyumri road and faced each other, neither side choosing to fight (June–July). On 4 August Russian scouts saw a movement which they thought was the start of a withdrawal, the Russians advanced and the Turks attacked first. They were defeated, losing 8000 men to the Russian 3000. 10000 irregulars deserted to their villages. Both sides withdrew to their former positions. About this time the Persians made a semi-secret agreement to remain neutral in exchange for the cancellation of the indemnity from the previous war.
On August 4th, who thought the other side was withdrawing? 
A: the Russians


Context and question: According to the Rev. John Gulick: "The inhabitants of other Asiatic nations, who have had occasion to represent the words of their several languages by Chinese characters, have as a rule used unaspirated characters for the sounds, g, d, b. The Muslims from Arabia and Persia have followed this method … The Mongols, Manchu, and Japanese also constantly select unaspirated characters to represent the sounds g, d, b, and j of their languages. These surrounding Asiatic nations, in writing Chinese words in their own alphabets, have uniformly used g, d, b, & c., to represent the unaspirated sounds."
Who constantly selected unaspirated characters?
Answer: Mongols, Manchu, and Japanese


Question: Hanover was founded in medieval times on the east bank of the River Leine. Its original name Honovere may mean "high (river)bank", though this is debated (cf. das Hohe Ufer). Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century due to its position at a natural crossroads. As overland travel was relatively difficult, its position on the upper navigable reaches of the river helped it to grow by increasing trade. It was connected to the Hanseatic League city of Bremen by the Leine, and was situated near the southern edge of the wide North German Plain and north-west of the Harz mountains, so that east-west traffic such as mule trains passed through it. Hanover was thus a gateway to the Rhine, Ruhr and Saar river valleys, their industrial areas which grew up to the southwest and the plains regions to the east and north, for overland traffic skirting the Harz between the Low Countries and Saxony or Thuringia.
Is there an answer to this question: What mountain was Hanover North East of?

Answer: unanswerable


Due to great differences in terrain, the climate of the province is highly variable. In general it has strong monsoonal influences, with rainfall heavily concentrated in the summer. Under the Köppen climate classification, the Sichuan Basin (including Chengdu) in the eastern half of the province experiences a humid subtropical climate (Köppen Cwa or Cfa), with long, hot, humid summers and short, mild to cool, dry and cloudy winters. Consequently, it has China's lowest sunshine totals. The western region has mountainous areas producing a cooler but sunnier climate. Having cool to very cold winters and mild summers, temperatures generally decrease with greater elevation. However, due to high altitude and its inland location, many areas such as Garze County and Zoige County in Sichuan exhibit a subarctic climate (Köppen Dwc)- featuring extremely cold winters down to -30 °C and even cold summer nights. The region is geologically active with landslides and earthquakes. Average elevation ranges from 2,000 to 3,500 meters; average temperatures range from 0 to 15 °C. The southern part of the province, including Panzhihua and Xichang, has a sunny climate with short, very mild winters and very warm to hot summers.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What climate classification does the Sichuan Basin hold?
Ah, so..
humid subtropical climate
