The problem: Answer a question about this article:
Coop et al. (2009) found "a selected allele that strongly differentiates the French from both the Yoruba and Han could be strongly clinal across Europe, or at high frequency in Europe and absent elsewhere, or follow any other distribution according to the geographic nature of the selective pressure. However, we see that the global geographic distributions of these putatively selected alleles are largely determined simply by their frequencies in Yoruba, French and Han (Figure 3). The global distributions fall into three major geographic patterns that we interpret as non-African sweeps, west Eurasian sweeps and East Asian sweeps, respectively."
Something that is found at high frequency in Europe could be what elsewhere?

The answer: absent

In sheer numbers, Kerry had fewer endorsements than Howard Dean, who was far ahead in the superdelegate race going into the Iowa caucuses in January 2004, although Kerry led the endorsement race in Iowa, New Hampshire, Arizona, South Carolina, New Mexico and Nevada. Kerry's main perceived weakness was in his neighboring state of New Hampshire and nearly all national polls. Most other states did not have updated polling numbers to give an accurate placing for the Kerry campaign before Iowa. Heading into the primaries, Kerry's campaign was largely seen as in trouble, particularly after he fired campaign manager Jim Jordan. The key factors enabling it to survive were when fellow Massachusetts Senator Ted Kennedy assigned Mary Beth Cahill to be the campaign manager, as well as Kerry's mortgaging his own home to lend the money to his campaign (while his wife was a billionaire, campaign finance rules prohibited using one's personal fortune). He also brought on the "magical" Michael Whouley who would be credited with helping bring home the Iowa victory the same as he did in New Hampshire for Al Gore in 2000 against Bill Bradley.
Who had the least amount of backers, between Kerry and Dean?
****
The answer: Kerry

The problem: Answer a question about this article:
The first technical dictionary was drafted by John Harris and entitled Lexicon Technicum: Or, An Universal English Dictionary of Arts and Sciences. Harris' book avoided theological and biographical entries; instead it concentrated on science and technology. Published in 1704, the Lexicon technicum was the first book to be written in English that took a methodical approach to describing mathematics and commercial arithmetic along with the physical sciences and navigation. Other technical dictionaries followed Harris' model, including Ephraim Chambers' Cyclopaedia (1728), which included five editions, and was a substantially larger work than Harris'. The folio edition of the work even included foldout engravings. The Cyclopaedia emphasized Newtonian theories, Lockean philosophy, and contained thorough examinations of technologies, such as engraving, brewing, and dyeing.
Did the Lexicon Technicum focus on theological and biographical entries or science and technology?
****
The answer: science and technology

Vinyl records can be warped by heat, improper storage, exposure to sunlight, or manufacturing defects such as excessively tight plastic shrinkwrap on the album cover. A small degree of warp was common, and allowing for it was part of the art of turntable and tonearm design. "wow" (once-per-revolution pitch variation) could result from warp, or from a spindle hole that was not precisely centered. Standard practice for LPs was to place the LP in a paper or plastic inner cover. This, if placed within the outer cardboard cover so that the opening was entirely within the outer cover, was said to reduce ingress of dust onto the record surface. Singles, with rare exceptions, had simple paper covers with no inner cover.
What is a cause of once per revolution pitch variation?

The answer:
warp, or from a spindle hole that was not precisely centered
