Question: Richard Sander claims that by artificially elevating minority students into schools they otherwise would not be capable of attending, this discourages them and tends to engender failure and high dropout rates for these students. For example, about half of black college students rank in the bottom 20 percent of their classes, black law school graduates are four times as likely to fail bar exams as are whites, and interracial friendships are more likely to form among students with relatively similar levels of academic preparation; thus, blacks and Hispanics are more socially integrated on campuses where they are less academically mismatched. He claims that the supposed "beneficiaries" of affirmative action minorities do not actually benefit and rather are harmed by the policy. Sander's claims have been disputed, and his empirical analyses have been subject to substantial criticism. A group including some of the country's lead statistical methodologists told the Supreme Court that Sander's analyses were sufficiently flawed that the Court would be wise to ignore them entirely. At the same time many scholars have found that minorities gain substantially from affirmative action.

Answer: Who claims that artificially raising minority students into schools has a negative effect on them?

Question: Denver took the opening kickoff and started out strong with Peyton Manning completing an 18-yard pass to tight end Owen Daniels and a 22-yard throw to receiver Andre Caldwell. A pair of carries by C. J. Anderson moved the ball up 20 yards to the Panthers 14-yard line, but Carolina's defense dug in over the next three plays. First, linebacker Shaq Thompson tackled Ronnie Hillman for a 3-yard loss. Then after an incompletion, Thomas Davis tackled Anderson for a 1-yard gain on third down, forcing Denver to settle for a 30 lead on a Brandon McManus 34-yard field goal. The score marked the first time in the entire postseason that Carolina was facing a deficit.

Answer: What team received the opening kickoff?

Question: The Egyptian singer Umm Kulthum hosted a public celebration for the officers' return despite reservations from the royal government, which had been pressured by the British to prevent the reception.

Nasser had also felt bitter that his brigade had not been relieved despite the resilience it displayed. He started writing his book Philosophy of the Revolution during the siege.

Answer:
What Egyptian singer performed at the return of Nasser's brigade?
