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
A 24-year study of 1,500 adults showed that those subjects with a high intake of foods rich in beta- carotene were much less likely to die from cancer or heart disease than were those with a low intake of such foods. On the other hand, taking beta-carotene supplements for 12 years had no positive or negative effect on the health of subjects in a separate study of 20,000 adults.
Each of the following, if true, would help to resolve the apparent discrepancy between the results of the two studies EXCEPT:CorrectIncorrect
- Question 2 of 5
If there are sentient beings on planets outside our solar system, we will not be able to determine this anytime in the near future unless some of these beings are at least as intelligent as humans. We will not be able to send spacecraft to planets outside our solar system anytime in the near future, and any sentient being on another planet capable of communicating with us anytime in the near future would have to be at least as intelligent as we are.
The argument’s conclusion can be properly inferred if which one of the following is assumed?CorrectIncorrect
- Question 3 of 5
Doctor: Medical researchers recently examined a large group of individuals who said that they had never experienced serious back pain. Half of the members of the group turned out to have bulging or slipped disks in their spines, conditions often blamed for serious back pain. Since these individuals with bulging or slipped disks evidently felt no pain from them, these conditions could not lead to serious back pain in people who do experience such pain.
The reasoning in the doctor’s argument is most vulnerable to the criticism that it fails to consider which one of the following possibilities?CorrectIncorrect
- Question 4 of 5
It is virtually certain that the government contract for building the new highway will be awarded to either Phoenix Contracting or Cartwright Company.

The argument proceeds byCorrectIncorrect
