QUES: However, some scholars contest the idea of a Proto-Euphratean language or one substrate language. It has been suggested by them and others, that the Sumerian language was originally that of the hunter and fisher peoples, who lived in the marshland and the Eastern Arabia littoral region, and were part of the Arabian bifacial culture. Reliable historical records begin much later; there are none in Sumer of any kind that have been dated before Enmebaragesi (c. 26th century BC). Professor Juris Zarins believes the Sumerians were settled along the coast of Eastern Arabia, today's Persian Gulf region, before it flooded at the end of the Ice Age.

QUES: Elevators with more than 30 m (98 ft) of travel have a system called compensation. This is a separate set of cables or a chain attached to the bottom of the counterweight and the bottom of the elevator cab. This makes it easier to control the elevator, as it compensates for the differing weight of cable between the hoist and the cab. If the elevator cab is at the top of the hoist-way, there is a short length of hoist cable above the car and a long length of compensating cable below the car and vice versa for the counterweight. If the compensation system uses cables, there will be an additional sheave in the pit below the elevator, to guide the cables. If the compensation system uses chains, the chain is guided by a bar mounted between the counterweight railway lines.
"Compensation" is the name of the system used for what type of elevators?

ANS: Elevators with more than 30 m (98 ft) of travel

A study in 2007 by Mark Long, an economics professor at the University of Washington, demonstrated that the alternatives of affirmative action proved ineffective in restoring minority enrollment in public flagship universities in California, Texas, and Washington. More specifically, apparent rebounds of minority enrollment can be explained by increasing minority enrollment in high schools of those states, and the beneficiaries of class-based (not race) affirmative action would be white students. At the same time, affirmative action itself is both morally and materially costly: 52 percent of white populace (compared to 14 percent of black) thought it should be abolished, implying white distaste of using racial identity, and full-file review is expected to cost the universities an additional $1.5 million to $2 million per year, excluding possible cost of litigation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In which year did Long reject his study?
Ah, so.. unanswerable

QUES: Genome-wide association studies have found 27 genetic variants that are associated with an increased risk of myocardial infarction. Strongest association of MI has been found with the 9p21 genomic locus, which contains genes CDKN2A & 2B, although the single nucleotide polymorphisms that are implicated are within a non-coding region. The majority of these variants are in regions that have not been previously implicated in coronary artery disease. The following genes have an association with MI: PCSK9, SORT1, MIA3, WDR12, MRAS, PHACTR1, LPA, TCF21, MTHFDSL, ZC3HC1, CDKN2A, 2B, ABO, PDGF0, APOA5, MNF1ASM283, COL4A1, HHIPC1, SMAD3, ADAMTS7, RAS1, SMG6, SNF8, LDLR, SLC5A3, MRPS6, KCNE2.
PCSK9 is found in what locus?
