Details of school casualties had been under non-governmental investigation since December 2008 by volunteers including artist and architect Ai Weiwei, who had been constantly posting updates on his blog since March 2009. The official tally of students killed in the earthquake was not released until May 7, 2009, almost a year after the earthquake. According to the state-run Xinhua news agency, the earthquake killed 5,335 students and left another 546 children disabled. In the aftermath of the earthquake, the Chinese government declared that parents who had lost their only children would get free treatment from fertility clinics to reverse vasectomies and tubal ligations conducted by family planning authorities.

What is the total of school children killed?
Answer: 5,335

Mathematicians often strive for a complete classification (or list) of a mathematical notion. In the context of finite groups, this aim leads to difficult mathematics. According to Lagrange's theorem, finite groups of order p, a prime number, are necessarily cyclic (abelian) groups Zp. Groups of order p2 can also be shown to be abelian, a statement which does not generalize to order p3, as the non-abelian group D4 of order 8 = 23 above shows. Computer algebra systems can be used to list small groups, but there is no classification of all finite groups.q["] An intermediate step is the classification of finite simple groups.r["] A nontrivial group is called simple if its only normal subgroups are the trivial group and the group itself.s["] The JordanHolder theorem exhibits finite simple groups as the building blocks for all finite groups. Listing all finite simple groups was a major achievement in contemporary group theory. 1998 Fields Medal winner Richard Borcherds succeeded in proving the monstrous moonshine conjectures, a surprising and deep relation between the largest finite simple sporadic groupthe "monster group"and certain modular functions, a piece of classical complex analysis, and string theory, a theory supposed to unify the description of many physical phenomena.

What level of finality do mathematicians try to reach with math concepts?
Answer: complete classification

BYU's social and cultural atmosphere is unique. The high rate of enrollment at the university by members of The Church of Jesus Christ of Latter-day Saints (more than 98 percent) results in an amplification of LDS cultural norms; BYU was ranked by The Princeton Review in 2008 as 14th in the nation for having the happiest students and highest quality of life. However, the quirkiness and sometimes "too nice" culture is often caricatured, for example, in terms of marrying early and being very conservative.

How was BYU ranked by The Princeton Review for having the happiest students and highest quality of life in 2008?
Answer:
14th in the nation
