A census of sea life carried out during the International Polar Year and which involved some 500 researchers was released in 2010. The research is part of the global Census of Marine Life (CoML) and has disclosed some remarkable findings. More than 235 marine organisms live in both polar regions, having bridged the gap of 12,000 km (7,456 mi). Large animals such as some cetaceans and birds make the round trip annually. More surprising are small forms of life such as mudworms, sea cucumbers and free-swimming snails found in both polar oceans. Various factors may aid in their distribution fairly uniform temperatures of the deep ocean at the poles and the equator which differ by no more than 5 C, and the major current systems or marine conveyor belt which transport eggs and larval stages.

Besides birds, what large animals travel from one pole to the other?
Answer: cetaceans

Problem: Although England's first away kits were blue, England's traditional away colours are red shirts, white shorts and red socks. In 1996, England's away kit was changed to grey shirts, shorts and socks. This kit was only worn three times, including against Germany in the semi-final of Euro 96 but the deviation from the traditional red was unpopular with supporters and the England away kit remained red until 2011, when a navy blue away kit was introduced. The away kit is also sometimes worn during home matches, when a new edition has been released to promote it.
What color are the socks traditionally worn in England's away kits?
The answer is the following: red

Ruben Studdard emerged as the winner, beating Clay Aiken by a small margin. Out of a total of 24 million votes, Studdard finished just 134,000 votes ahead of Aiken. This slim margin of victory was controversial due to the large number of calls that failed to get through. In an interview prior to season five, executive producer Nigel Lythgoe indicated that Aiken had led the fan voting from the wildcard week onward until the finale.
Who was the runner up on season two of American Idol?

Input: John Kerry
In the State Department, Kerry quickly earned a reputation "for being aloof, keeping to himself, and not bothering to read staff memos." Career State Department officials have complained that power has become too centralized under Kerry's leadership, which slows department operations when Kerry is on one of his frequent overseas trips. Others in State describe Kerry as having "a kind of diplomatic attention deficit disorder" as he shifts from topic to topic instead of focusing on long-term strategy. When asked whether he was traveling too much, he responded, "Hell no. I'm not slowing down." Despite Kerry's early achievements, morale at State is lower than under Hillary Clinton according to department employees. However, after Kerry's first six months in the State Department, a Gallup poll found he had high approval ratings among Americans as Secretary of State. After a year, another poll showed Kerry's favorability continued to rise. Less than two years into Kerry's term, the Foreign Policy Magazine's 2014 Ivory Tower survey of international relations scholars asked, "Who was the most effective U.S. Secretary of State in the past 50 years?"; John Kerry and Lawrence Eagleburger tied for 11th place out of the 15 confirmed Secretaries of State in that period.

How had some State employees described Kerry?
Output: having "a kind of diplomatic attention deficit disorder"

Problem: Please answer a question about the following article about Affirmative action in the United States:
The controversy surrounding affirmative action's effectiveness is based on the idea of class inequality. Opponents of racial affirmative action argue that the program actually benefits middle- and upper-class African Americans and Hispanic Americans at the expense of lower-class European Americans and Asian Americans. This argument supports the idea of class-based affirmative action. America's poor is disproportionately made up of people of color, so class-based affirmative action would disproportionately help people of color. This would eliminate the need for race-based affirmative action as well as reducing any disproportionate benefits for middle- and upper-class people of color.
Which idea is the controversy of affirmative action primarily based upon?
A:
class inequality
