WeakenDiff: Medium

Logic Breakdown

Passage Summary: A drug company spent more on sales people, but each person made fewer visits, so the author assumes doctors are now slamming the door in their faces.

Conclusion: The increase in pharmaceutical promotion was actually counterproductive, causing doctors to be less open to seeing sales representatives.

Reasoning: Even though spending on sales reps increased, the average number of visits per representative decreased significantly.

Analysis: This argument suffers from a 'numbers and percentages' flaw. If the company hired a massive number of new representatives, the total number of visits could have skyrocketed even if the average per person went down. To weaken this, look for an answer that provides an alternative explanation for the lower average, such as a massive increase in the total sales force or a change in how visits are conducted.

Which one of the following, if true, most weakens the argument?

Correct Answer
A
If most manufacturers increased the size of their sales forces so each rep could devote more time to each physician, then the average visits per rep would drop simply because the same or greater total pool of visits is spread across more reps and/or visits are longer. That undercuts the claim that physicians became less willing as a result of the extra promotion.
