Review these reasoning quizzes right after you do them. For anything that you’re not 100% on google the first bunch of words of the question and seek out explanations online. If after spending some time reviewing you’re still having a tough time then bring the question to QA or to your next tutoring session. Really fight to understand the logic of these questions. Remember: 1 is correct 4 are incorrect. Really push yourself to be black and white with correct v. incorrect. It is extremely rare that two answer choices are technically OK but one is stronger. It can happen but we’re talking 1% of the time. So, with that in mind let’s have the mindset that it never happens and that we need to be binary: 1 correct. 4 incorrect. That mindset is key to improvement.
Question 1 of 5
Acquiring complete detailed information about all the pros and cons of a product one might purchase would clearly be difficult and expensive. It is rational not to acquire such information unless one expects that the benefits of doing so will outweigh the cost and difficulty of doing so. Therefore, consumers who do not bother to acquire such information are thereby behaving rationally.
The conclusion of the argument is properly drawn if which one of the following is assumed?CorrectIncorrect
Question 2 of 5
A new process enables ordinary table salt to be fortified with iron. This advance could help reduce the high incidence of anemia in the world’s population due to a deficiency of iron in the diet. Salt is used as a preservative for food and a flavor enhancer all over the globe, and people consume salt in quantities that would provide iron in significant amounts.
Which one of the following most accurately describes the role played in the argument by the statement that people consume salt in quantities that would provide iron in significant amounts?CorrectIncorrect
Question 3 of 5
Populations of a shrimp species at eleven different Indonesian coral reefs show substantial genetic differences from one reef to another. This is surprising because the area’s strong ocean currents probably carry baby shrimp between the different reefs, which would allow the populations to interbreed and become genetically indistinguishable.
Which one of the following, if true, most helps to explain the substantial genetic differences among the shrimp populations?CorrectIncorrect
Question 4 of 5
Researchers have studied the cost-effectiveness of growing halophytes—salt-tolerant plant species—for animal forage. Halophytes require more water than conventional crops, but can be irrigated with seawater, and pumping seawater into farms near sea level is much cheaper than pumping freshwater from deep wells. Thus, seawater agriculture near sea level should be cost-effective in desert regions although its yields are smaller than traditional, freshwater agriculture.
Which one of the following, if true, most strengthens the argument above?CorrectIncorrect
Question 5 of 5
Researcher: Every year approximately the same number of people die of iatrogenic “disease”—that is, as a direct result of medical treatments or hospitalization—as die of all other causes combined. Therefore, if medicine could find ways of preventing all iatrogenic disease, the number of deaths per year would decrease by half.
The reasoning in the researcher’s argument is flawed because the argument fails to consider thatCorrectIncorrect
