School Principal: Recent testing indicates that students in our school are struggling in math. At this time, the students are spending only forty-five minutes each day on math lessons. The testing also indicates that students are excelling in reading, however. The students currently spend one and a half hours each day on reading. Therefore, we need to increase the amount of time spent on math in order to improve the math skills of students in our school.

The weakness in the school principal's argument is similar to the weakness in which of the following arguments?

A. Family psychologists have found that the children with the best speech development are those whose parents read to them at an early age. Therefore, all parents should read to their young children in order to enhance their speech development skills.

B. Travel agents routinely see that families who have the most comfortable and relaxing vacations are those who stay in three- or four-star resorts. Therefore, any family hoping to have a comfortable and relaxing vacation should restrict accommodation choices to three- and four-star resorts.

C. Research has shown that traders who put their money in options tend to be more likely to suffer from losing trades. Research also suggests that traders who put their money in stocks, which require a larger investment up front, tend to be more successful. Therefore, traders should put their money into stocks if they hope to have winning trades.

D. Studies suggest that students who are most successful in college have attended advanced placement classes in high school. Therefore, those students who hope to be most successful in college should strive to be accepted into advanced placement classes.

E. Caitlyn and Moira discovered that Caitlyn was spending a little more than Moira at the grocery story each month. But Moira usually stopped at the grocery store several times each week, while Caitlyn never shopped more than once a week. Therefore, Caitlyn and Moira are actually spending the same amount, because Moira must pay the extra cost of gas for several trips to the store.

Was confused between B and C.
C seems to be more apt than B.
Is it C?

IMO C.

Both draw casual correlation on the basis of the proportions of quantifiable investments (time and money) and ignore other (possibly unquantifiable/intangible) factors.

Technique which can be used in above type of CR is to eliminate incorrect choices.

One particular technique which can be useful is to eliminate options which are same/parallel.

Here in above question option B and D are parallel.

Once you realize this question can be solved easily.

A) and E) easy to eliminate.

B) and D) out with above reasoning.

Ans C)

Only Option C gives similar reasoning(weakness) to the stimulus where the traders put their money into stocks if they hope to have winning more trades is equivalent to the students investing more time in Math to score well.
