101. Amy: “It is a proven fact that wind can provide a more reliable source of energy than fossil fuels. Dr. Malcolm Wolf recently produced a paper explaining that there is essentially unlimited potential for wind power.”

Zack: “That claim cannot be correct. Dr. Wolf was found to have fabricated another study about solar power, and so his opinions cannot be trusted.”

Zack’s argument against Amy’s assertions is most vulnerable to criticism because it
  1. Tries to show Amy's conclusions are more extreme and outrageous than they really are.
  2. Tries to claim that because Dr. Wolf has done bad research in the past, then he must be intentionally lying and therefore can’t be trusted.
  3. Tries to claim that because Dr. Wolf has been wrong about other things in the past, then he must be wrong this time as well.
  4. Assumes, without providing justification, that Amy is unable to properly understand the findings of the study she cites.
  5. Assumes, without providing justification, that Amy misinterpreted the findings of the study, and the truth is really the opposite of what she thinks.

102. Company president: “Despite the wishes of the shareholders, I believe that expanding our company from just catering into a sit-down restaurant is not a wise move. Expanding into a restaurant would be costly and the restaurant industry is incredibly volatile. Furthermore, we already had plans to expand our already successful catering business into other geographic areas, and opening a restaurant would take funds away from those endeavors.”

If the president’s statement is true, which of the following is most strongly supported by it?
  1. The shareholders do not have the best interest of the company in mind.
  2. The restaurant industry is too competitive for new entrants to succeed.
  3. Only if the company expands into other geographic areas will the company continue to be successful.
  4. If the company wants to grow, it would be more successful expanding its catering business than opening a restaurant.
  5. The company will fail if it opens a restaurant.

103. Senator: “I do not agree with the nomination of Judge Azizi for the Supreme Court. There are credible allegations of bias against Azizi, making many in my party wary of his appointment. In addition, regardless of the veracity of the claims against Azizi, he is clearly unqualified for the appointment. He has never served as a judge before and lacks the qualifications necessary for the appointment and so should not be appointed to the Court.”

Which of the following principles, if valid, most helps to justify the senator’s conclusion?
  1. Appropriate experience is the most important requirement to serving on the Supreme Court.
  2. The mere hint of bias should be enough to prevent an appointment of a judge.
  3. In appointing a judge, all relevant qualifications should be weighed equally.
  4. A judge cannot be appointed if he could be biased, even if he is qualified.
  5. A suspicion of bias is not enough to disqualify someone for a position.

104. The manufacturers of a popular diet drug claim that the drug can help reduce food cravings in order to aid in weight loss. But in a recent study, researchers proved that the main ingredient in the drug has no effect on weight loss. If another study proves that the other ingredients, of which there are only three, also have no effect on weight loss, then clearly the drug is not actually effective.

The argument is flawed because it
  1. Presumes that a combination must lack a specific quality if each individual part also lacks that quality.
  2. Confuses cause with correlation.
  3. Relies on an unrepresentative sample to draw broad conclusions.
  4. Assumes that a claim must be false if the person behind the claim has a proven bias.
  5. Overlooks the possibility that acting as a placebo is a valid use for a drug.

105. Pediatrician: “Recent research has shown that babies or young children to nature can reduce the risk of developing allergies to pollen or grass. Therefore, instead of protecting children from the natural world, we should encourage them to play outside and allow them to get dirty. However, one should take this advice with caution. While it may be true that exposure to nature while young prevents allergies, it could increase exposure to other diseases and we don’t yet know about other effects from such a practice.”

Which of the following most accurately expresses the main conclusion of the pediatrician’s argument?
  1. We should expose young children to the natural world in order to prevent allergies.
  2. We should allow children to play outside more often.
  3. We don’t yet know the full effects of exposing young children to the outdoors so we should follow the advice of a recent study with caution.
  4. There is next to nothing we can do to prevent allergies from forming in children.
  5. We try far too hard to protect young children from the natural world instead of allowing them to discover it for themselves.
