Here is a question about this article: Assuming the player's optical pickup is in proper working order, crosstalk distortion normally does not occur during playback of CAV format LaserDiscs, as the rotational speed never varies. However, if the player calibration is out of order or if the CAV disc is faulty or damaged, other problems affecting tracking accuracy can occur. One such problem is "laser lock", where the player reads the same two fields for a given frame over and over again, causing the picture to look frozen as if the movie were paused.
What is the answer to this question: Why does the CAV format prevent crosstalk?
****
So... the rotational speed never varies

The problem: Answer a question about this article:
From July to September 1989, Voyager 2 discovered six moons of Neptune. Of these, the irregularly shaped Proteus is notable for being as large as a body of its density can be without being pulled into a spherical shape by its own gravity. Although the second-most-massive Neptunian moon, it is only 0.25% the mass of Triton. Neptune's innermost four moonsNaiad, Thalassa, Despina and Galateaorbit close enough to be within Neptune's rings. The next-farthest out, Larissa, was originally discovered in 1981 when it had occulted a star. This occultation had been attributed to ring arcs, but when Voyager 2 observed Neptune in 1989, Larissa was found to have caused it. Five new irregular moons discovered between 2002 and 2003 were announced in 2004. A new moon and the smallest yet, S/2004 N 1, was found in 2013. Because Neptune was the Roman god of the sea, Neptune's moons have been named after lesser sea gods.
What is notable about the moon Proteus?
****
The answer: irregularly shaped

Problem: Please answer a question about the following article about Washington University in St. Louis:
During fiscal year 2007, $537.5 million was received in total research support, including $444 million in federal obligations. The University has over 150 National Institutes of Health funded inventions, with many of them licensed to private companies. Governmental agencies and non-profit foundations such as the NIH, United States Department of Defense, National Science Foundation, and NASA provide the majority of research grant funding, with Washington University being one of the top recipients in NIH grants from year-to-year. Nearly 80% of NIH grants to institutions in the state of Missouri went to Washington University alone in 2007. Washington University and its Medical School play a large part in the Human Genome Project, where it contributes approximately 25% of the finished sequence. The Genome Sequencing Center has decoded the genome of many animals, plants, and cellular organisms, including the platypus, chimpanzee, cat, and corn.
What are some organisms for which the Genome Sequencing Center at Washington University Medical provided genome decoding?
A: platypus, chimpanzee, cat, and corn

Question: Read this and answer the question

On 19 November 1968, following progressive economic decline, the Keita regime was overthrown in a bloodless military coup led by Moussa Traore, a day which is now commemorated as Liberation Day. The subsequent military-led regime, with Traore as president, attempted to reform the economy. His efforts were frustrated by political turmoil and a devastating drought between 1968 to 1974, in which famine killed thousands of people. The Traore regime faced student unrest beginning in the late 1970s and three coup attempts. The Traore regime repressed all dissenters until the late 1980s.

In the 1970's how many attempts were there the overthrow the govenment?
Answer: three coup attempts

Problem: Unlike in Westminster style legislatures or as with the Senate Majority Leader, the House Majority Leader's duties and prominence vary depending upon the style and power of the Speaker of the House. Typically, the Speaker does not participate in debate and rarely votes on the floor. In some cases, Majority Leaders have been more influential than the Speaker; notably Tom DeLay who was more prominent than Speaker Dennis Hastert. In addition, Speaker Newt Gingrich delegated to Dick Armey an unprecedented level of authority over scheduling legislation on the House floor.
Who was speaker of the house When Tom Delay was Majority leader?
The answer is the following: Dennis Hastert

Input: Article: Catalan shares many traits with the other neighboring Romance languages (Italian, Sardinian, Occitan, and Spanish). However, despite being mostly situated in the Iberian Peninsula, Catalan has marked differences with the Ibero-Romance group (Spanish and Portuguese) in terms of pronunciation, grammar, and especially vocabulary; showing instead its closest affinity with Occitan and to a lesser extent Gallo-Romance (French, Franco-Provencal, Gallo-Italian).

Now answer this question: In pronunciation what is Catalan different from?

Output:
Ibero-Romance group
