Critical Reasoning: Conclusion Strengthening Questions

Anny Chross is a known detective novelist. Having noticed a survey stating that readers between the ages of 18 and 24 prefer a relatively simple detective story over a more complicated narrative which makes more demands on the reader, Ms. Chross has decided to change the plot to make it easier to comprehend by her readership.

Which of the following, if true, most seriously strengthens Ms. Chross's decision?

Incorrect.

[[snippet]]

This answer choice is irrelevant to the argument as we are discussing the plots of detective novels, not love stories.

Incorrect.

[[snippet]]

The preference of paperback over hard cover have nothing to do with Anny Chross' decision to make the plot of her next novel more simple; therefore, this answer choice cannot be said to strengthen that decision.

Right on the spot!

[[snippet]]

This answer choice strengthens Chross' decision by confirming her assumption: if most of Chross' readership is between 18-24 (adults=18 and up, younger than 25=24), the survey findings apply to her readership and simplifying the plot to fit this age group's preferences makes more sense.

Incorrect.

[[snippet]]

This answer choice emphasizes the inherent assumption in Chross' argument, thereby weakening it. If Chross' readership spans all ages between 14 and 80+, a decision to change her plot to meet the preference of a relatively small group of young adults makes less sense.

Incorrect.

[[snippet]]

This answer choice weakens Anny Chross' decision by citing an alternative case, the case of older adults, who dislike simple plots (unlike young adults). This data supports not simplifying the plots; however, you were asked to find data that promotes Chross' decision to simplify her plots.

Readers of love stories between the ages of 18-24 prefer to read relatively simple plotted books.
Readers of detective novels prefer buying paperback over hard cover, as the former tend to cost significantly less.
58.5% of Anny Chross' readers are adults younger than 25 years old.
Readers between the ages of 35-44 find relatively simple plots uninteresting.
The age range of Anny Chross' readership spans between 14 to over 80 years old.
