The times and amplitude of neap tides, the low amplitude tides that occur during first and third quarters of the lunar month, are due to not only the cancellation of the tidal forces of the Sun and the Moon but also a host of factors—amphidromic systems, the shape of coastline, and near-shore bathymetry—any of which can lead to significant fluctuations in the time and amplitude of neap tides only miles apart.

If medical researchers are correct, then the human microbiome, made up of the microorganisms in our body, may hold the cure to diseases that have long plagued humanity, amounting to a major oversight in Western medicine that has, until recently, all but ignored any such role of the microbiome.

A large number of famous poets in literary history have died under the age of 40 --- Burns, Byron, Keats, Poe, and Shelley, to name a few. By contrast, the large majority of famous painters in art history lived well beyond the age of 40.

The TJ-700 and the Beta Turbomax are two models of cars of different manufacturers. These two models have almost identical specifications and features, and they sell for almost the same price. Both were introduced on the market five years ago, and each year, the respective manufacturers spend about the same amount in advertising. In the past five year, the total number of TJ-700's sold is about 80% greater than the total number of Beta Turbomax's sold. Clearly, the advertising firm that created TJ-700 ads created much more effective ads than the firm that created Beta Turbomax ads. In evaluating the argument, it would be most useful to know which of the following?

Epidemiologist: Malaria passes into the human population when a mosquito carrying the malaria protozoa bites a human who has no immunity. The malaria parasite can remain for up to forty days in the blood of an infected person. The disease cannot be passed from person to person, unless a non-infected person is exposed to the blood of an infected person. Theoretically, malaria could be eradicated in any given area, if all the mosquitoes carrying malaria in that area are exterminated. If such a course of action is carried out at a worldwide level, then the global eradication of malaria is possible. Which of the following, if true, suggests that the epidemiologist's plan for eliminating malaria is not viable?

A sports arena is considering a new stadium design, one in which each block of seats would be in an enclosed weather-proof room with a view of the playing field and a large screen TV showing the action of play, including the instant replays typical of television broadcasts of sports games. The developer reasons that exposure to elements and lack of access to instant replays significantly limits the typical spectator's enjoyment of the live game.This stadium design would be unlikely to increase the pleasure the spectators take from live games if they enjoyed

A table made entirely from the trunk of a tree said to have lived a thousand years was recently claimed to be that of a much younger tree. In order to rebut this charge, the craftsman summoned a team of dendrochronologists to prove that the tree lived to be at least to 1,000 years old. Dendrochronology, or the technique of using tree rings to date wood, is based on the fact that for each passing year a tree develops exactly one ring, as seen in a horizontal cross-section of the trunk. Given that dendrochronology is accurate for trees that lived less than 2,000 total years, the dendrochronologists will be able to determine whether the work comes from a tree that lived to be at least 1,000 years old.Which of the following is an assumption that the argument makes?

Algorpal Industries produces high quality pneumatic filters. For years, they have primarily served manufacturers of domestic agricultural equipment, and over time, this market has been decreasing. A consultant recommended that, with a minor modification, Algorpal could expand into pneumatic filters for biomedical research technology, a rapidly expanding market. The consultant argued that this single change could reverse a ten-year decline in Algorpal's profits. Which of the following would be the most useful to establish in evaluating the consultant's recommendation?

Last year, a woman was able to demonstrate that she contracted a bad case of food poisoning from a meal at one Chinese restaurant in Bairenville, and she successfully sued the restaurant for a large sum of money. The story was popular in the town, and the size of the financial settlement made the national news. This year, we have seen a number of "copycat" suits filed against each one of the eleven Chinese restaurants in Bairenville, forcing these restaurants to hire lawyers and take steps to defend themselves in court.Which of following conclusions can most properly be drawn from the information above?

A minor league baseball franchise experienced a drop in attendance this week after they suffered three losses by margins of ten runs or more last week. Many spectators of those games wrote letters to the editors of the local sporting news, complaining of the poor play of the team in those three losses. Nevertheless, the front office of this baseball franchise maintains that the team's poor play in those three losses has nothing to do with this week's decline in attendance.Which of the following, if true, most strongly supports the position held by the front office of the baseball franchise?

The rate of health complications of patients on intravenous (IV) therapy at a particular hospital was higher than usual. Government inspectors found that the typical IV solutions used in this hospital had somewhat high concentrations of sodium and potassium, which were raising patients' blood pressure and taxing their kidneys. The government inspectors mandated lowering the sodium and potassium in these IV preparations, and threatened with a possible government fine. In compliance, the hospital lowered the sodium and potassium levels in the IV solutions to the correct levels. Nevertheless, patients on IV therapy at that hospital continued to have a high rate of health complications.Which of the following, if true, most helps to explain why acting on the government inspectors' recommendations failed to achieve its goal?

In a few recent cases, some teenagers with advanced programming abilities used a new programming language, FANTOD, to hack into ETS and change their own SAT scores. All of the teenagers convicted of this crime were highly skilled in programming FANTOD. In light of these cases, some colleges have discounted the official SAT scores of applicants with a knowledge of FANTOD, and have required them to take special admission tests in supervised conditions on their own campuses.Which of following conclusions can most properly be drawn from the information above?
