The problem: Answer a question about this article:
The gyromagnetic ratio is the constant of proportionality between the frequency of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field B: = B. It is difficult to measure gyromagnetic ratios precisely because of the difficulties in precisely measuring B, but the value for protons in water at 7002298150000000000♠️25 C is known to better than one part per million. The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule, the same effect that gives rise to chemical shift in NMR spectroscopy, and this is indicated by a prime on the symbol for the gyromagnetic ratio, p. The gyromagnetic ratio is related to the shielded proton magnetic moment p, the spin number I (I = 12 for protons) and the reduced Planck constant.
How does the water molecule impact the effect of magnetic fields on protons?

The answer: The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule

The problem: Answer a question about this article:
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.
Who published the Ivory Tower Survey?
****
The answer: Foreign Policy Magazine

The city of Richmond operates 28 elementary schools, nine middle schools, and eight high schools, serving a total student population of 24,000 students. There is one Governor's School in the city the Maggie L. Walker Governor's School for Government and International Studies. In 2008, it was named as one of Newsweek magazine's 18 "public elite" high schools, and in 2012, it was rated #16 of America's best high schools overall. Richmond's public school district also runs one of Virginia's four public charter schools, the Patrick Henry School of Science and Arts, which was founded in 2010.
How many high schools are there in Richmond?
****
The answer: eight

The problem: Answer a question about this article:
Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 12% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
What sort of variants did the Human Genome Project indicate that many of the measured transcripts were?
****
The answer:
alternative variants
