Input: Dog
Domestic dogs often display the remnants of countershading, a common natural camouflage pattern. A countershaded animal will have dark coloring on its upper surfaces and light coloring below, which reduces its general visibility. Thus, many breeds will have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.

A natural camo pattern is known as what?
Output: countershading


Input: Article: During Reconstruction, freedmen and former free people of color were granted the right to vote; most joined the Republican Party. Numerous African Americans were elected to local offices, and some to state office. Following Reconstruction, Tennessee continued to have competitive party politics. But in the 1880s, the white-dominated state government passed four laws, the last of which imposed a poll tax requirement for voter registration. These served to disenfranchise most African Americans, and their power in the Republican Party, the state, and cities where they had significant population was markedly reduced. In 1900 African Americans comprised 23.8 percent of the state's population, concentrated in Middle and West Tennessee. In the early 1900s, the state legislature approved a form of commission government for cities based on at-large voting for a few positions on a Board of Commission; several adopted this as another means to limit African-American political participation. In 1913 the state legislature enacted a bill enabling cities to adopt this structure without legislative approval.

Now answer this question: In which decade did the Tennessee legislature institute a poll tax?

Output: 1880s


Article: In 1926 Joseph P. Maxwell and Henry C. Harrison from Bell Telephone Laboratories disclosed that the recording pattern of the Western Electric "rubber line" magnetic disc cutter had a constant velocity characteristic. This meant that as frequency increased in the treble, recording amplitude decreased. Conversely, in the bass as frequency decreased, recording amplitude increased. Therefore, it was necessary to attenuate the bass frequencies below about 250 Hz, the bass turnover point, in the amplified microphone signal fed to the recording head. Otherwise, bass modulation became excessive and overcutting took place into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary. G. H. Miller in 1934 reported that when complementary boost at the turnover point was used in radio broadcasts of records, the reproduction was more realistic and many of the musical instruments stood out in their true form.

Question: What is found when a complementary boost is used at the bass turnover point?
Ans: reproduction was more realistic


Here is a question about this article: The influence of Old Norse certainly helped move English from a synthetic language along the continuum to a more analytic word order, and Old Norse most likely made a greater impact on the English language than any other language. The eagerness of Vikings in the Danelaw to communicate with their southern Anglo-Saxon neighbors produced a friction that led to the erosion of the complicated inflectional word-endings. Simeon Potter notes: “No less far-reaching was the influence of Scandinavian upon the inflexional endings of English in hastening that wearing away and leveling of grammatical forms which gradually spread from north to south. It was, after all, a salutary influence. The gain was greater than the loss. There was a gain in directness, in clarity, and in strength.”
What is the answer to this question: What was the name of the area in England ruled by the Vikings?
****
So... the Danelaw

With the continuing controversy that had surrounded the military service of George W. Bush since the 2000 Presidential election (when he was accused of having used his father's political influence to gain entrance to the Texas Air National Guard, thereby protecting himself from conscription into the United States Army, and possible service in the Vietnam War), John Kerry's contrasting status as a decorated Vietnam War veteran posed a problem for Bush's re-election campaign, which Republicans sought to counter by calling Kerry's war record into question. As the presidential campaign of 2004 developed, approximately 250 members of a group called Swift Boat Veterans for Truth (SBVT, later renamed Swift Vets and POWs for Truth) opposed Kerry's campaign. The group held press conferences, ran ads and endorsed a book questioning Kerry's service record and his military awards. The group included several members of Kerry's unit, such as Larry Thurlow, who commanded a swift boat alongside of Kerry's, and Stephen Gardner, who served on Kerry's boat. The campaign inspired the widely used political pejorative 'swiftboating', to describe an unfair or untrue political attack. Most of Kerry's former crewmates have stated that SBVT's allegations are false.
Who kept George W. Bush out of Vietnam?
****
The answer: his father


The problem: Answer a question about this article:
An exceptionally well preserved, carpet-like mosaic floor was uncovered in 1949 in Bethany, the early Byzantine church of the Lazarium which was built between 333 and 390. Because of its purely geometrical pattern, the church floor is to be grouped with other mosaics of the time in Palestine and neighboring areas, especially the Constantinian mosaics in the central nave at Bethlehem. A second church was built above the older one during the 6th century with another more simple geometric mosaic floor.
A church was built on top of the Byzantine church of the Lazarium in waht century?
****
The answer:
the 6th
