116. While many people believe that fraud is more common than ever before, it is actually much more difficult to complete a fraudulent transaction at a bank than in past years. Most banking systems are now automated, so there is less room for human error or manipulation. In addition, modern computer systems can detect suspicious activity and alert appropriate staff.

Each of the following statements would weaken the above passage EXCEPT
  1. The percentage of people losing money to fraudulent bank transactions has actually increased in the past 30 years.
  2. Most bank tellers will now allow you to complete a transaction without an ID as long as you know a password.
  3. Computer programs detecting fraud are vulnerable to hackers and occasionally are successfully dismantled.
  4. Since most people now use debit cards instead of checks, the chances of a checkbook falling into the wrong hands have declined.
  5. Staff levels at banks have declined, so even if computer systems alert them to fraudulent transactions, the staff often has too many customers to notify.

117. Scientist: While studying fossil records for ancient mammal species, I unexpectedly discovered that one million years ago the amount of flora covering what is now Canada was much lower than it is today. Clearly the climate must have been significantly different then to explain such a large difference in flora.

The reasoning in the scientist’s argument is most vulnerable to criticism on the grounds that it
  1. Presumes, without providing justification, that the prevalence of species of mammals and flora are related.
  2. Makes an inference without enough evidence to support the claim.
  3. Draws a general conclusion from an unrepresentative sample.
  4. Takes for granted that the method used for gathering the data was reliable.
  5. Inappropriately uses a general observation to make a specific claim.

118. Larry: “I only eat organic, natural food products so I won’t eat anything that has a complicated sounding label. If I can’t pronounce it, it’s not natural.”

Giselle: “But that’s not really true. Many healthy, normal ingredients are listed by their chemical compound name. For example, plain, natural salt could be listed as sodium chloride.”

Giselle is most likely to agree with which of the following statements?
  1. It is not important to read nutrition labels because they are intentionally misleading.
  2. It is important to understand all names for food ingredients in order to understand food labels.
  3. Food ingredients should always be listed in the simplest terms to avoid confusing people.
  4. Organic products are only products that are labeled organic.
  5. Any product that has a complicated sounding name can be trusted to be inorganic.

119. Nelson is a very respected sociologist, but his latest work is a disgrace. He relied on previous work done by other colleagues, an unreliable method of gathering research data. The work those colleagues completed has never been peer-reviewed, so it is clearly without merit. Therefore Nelson’s new work is clearly lacking in academic merit.

The reasoning above is flawed because it
  1. Presumes, without providing justification, that popular opinion is an appropriate metric for judging a work.
  2. Presumes, without providing justification, that because research is not peer-reviewed it is unreliable.
  3. Bases a general conclusion from a single observation.
  4. Uses reputation instead of substance to judge research.
  5. Uses substance to judge a work while ignoring reputation.

120. More and more people eat protein shakes for breakfast instead of cereal. Clearly, people are tired of eating breakfast cereal and are craving alternatives. Since cereal is cheaper than breakfast shakes, no one would willingly switch to drinking protein shakes unless they were tired of eating cereal.

The reasoning above is most vulnerable to criticism on the grounds it
  1. Fails to consider alternative reasons for why people would switch to protein shakes.
  2. Presumes that the nutritional content of cereal and shakes is the same.
  3. Presumes that the same amount of people always eat breakfast.
  4. Fails to produce statistical evidence supporting its claim.
  5. Assumes that price is a relevant factor when choosing a breakfast.
