Problem: Aspirated consonant:

They are unaspirated for almost all speakers when immediately following word-initial s, as in spill, still, skill. After an s elsewhere in a word they are normally unaspirated as well, except sometimes in compound words. When the consonants in a cluster like st are analyzed as belonging to different morphemes (heteromorphemic) the stop is aspirated, but when they are analyzed as belonging to one morpheme the stop is unaspirated.[citation needed] For instance, distend has unaspirated [t] since it is not analyzed as two morphemes, but distaste has an aspirated middle [t] because it is analyzed as dis- + taste and the word taste has an aspirated initial t.

What word-initial is aspirated for almost all speakers?

Problem: Memories and lessons from the war are still a major factor in American politics. One side views the war as a necessary part of the Containment policy, which allowed the enemy to choose the time and place of warfare. Others note the U.S. made major strategic gains as the Communists were defeated in Indonesia, and by 1972 both Moscow and Beijing were competing for American support, at the expense of their allies in Hanoi. Critics see the conflict as a "quagmire"an endless waste of American blood and treasure in a conflict that did not concern US interests. Fears of another quagmire have been major factors in foreign policy debates ever since. The draft became extremely unpopular, and President Nixon ended it in 1973, forcing the military (the Army especially) to rely entirely upon volunteers. That raised the issue of how well the professional military reflected overall American society and values; the soldiers typically took the position that their service represented the highest and best American values.
When did the draft begin?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Japan saw the release of the Satellaview, a modem which attached to the Super Famicom's expansion port and connected to the St.GIGA satellite radio station. Users of the Satellaview could download gaming news and specially designed games, which were frequently either remakes of or sequels to older Famicom titles, released in installments. Satellaview signals were broadcast from April 23, 1995 through June 30, 2000. In the United States, the similar but relatively short-lived XBAND allowed users to connect to a network via a dial-up modem to compete against other players around the country.
What kind of games were downloaded on XBAND to compete in Japan?
A: unanswerable

Context and question: The institutes of technology and polytechnics have been in existence since at least the 18th century, but became popular after World War II with the expansion of engineering and applied science education, associated with the new needs created by industrialization. The world's first institution of technology, the Berg-Schola (today its legal successor is the University of Miskolc) was founded by the Court Chamber of Vienna in Selmecbanya, Kingdom of Hungary in 1735 in order to train specialists of precious metal and copper mining according to the requirements of the industrial revolution in Hungary. The oldest German Institute of Technology is the Braunschweig University of Technology (founded in 1745 as "Collegium Carolinum"). Another exception is the Ecole Polytechnique, which has educated French elites since its foundation in 1794. In some cases, polytechnics or institutes of technology are engineering schools or technical colleges.
What was the founding name of the Braunschweig University of Technology?
Answer: Collegium Carolinum

Question: Mark Twain provided humorously telling evidence for the frequent unreliability of back-translation when he issued his own back-translation of a French translation of his short story, "The Celebrated Jumping Frog of Calaveras County". He published his back-translation in a 1903 volume together with his English-language original, the French translation, and a "Private History of the 'Jumping Frog' Story". The latter included a synopsized adaptation of his story that Twain stated had appeared, unattributed to Twain, in a Professor Sidgwick's Greek Prose Composition (p. 116) under the title, "The Athenian and the Frog"; the adaptation had for a time been taken for an independent ancient Greek precursor to Twain's "Jumping Frog" story.
Is there an answer to this question: What language did Twain remove a back-translation?

Answer: unanswerable

Problem: Anti-aircraft warfare:

The US ended World War I with two 3-inch AA guns and improvements were developed throughout the inter-war period. However, in 1924 work started on a new 105 mm static mounting AA gun, but only a few were produced by the mid-1930s because by this time work had started on the 90 mm AA gun, with mobile carriages and static mountings able to engage air, sea and ground targets. The M1 version was approved in 1940. During the 1920s there was some work on a 4.7-inch which lapsed, but revived in 1937, leading to a new gun in 1944.

Only a few of the 105 mm static mounting AA guns were produced because work had started on which other gun?
---
A:
90 mm AA gun
