Since Theall’s, a retail store located in Beach Haven, had a strong year two years ago, management decided last year that the store could afford to advertise more during the summer last year than it had in previous summers. Then, last year, Theall’s sales in the summer were stronger than in any previous summer.
Determining which of the following would be most helpful in determining whether the increase in sales can be attributed to the increase in advertising spending?In this question, the conclusion is not stated in the passage. Rather, the conclusion is presented in question stem. So, to answer this question, we have to evaluate the case for the following conclusion:
the increase in sales can be attributed to the increase in advertising spending The passage presents some support for the conclusion, which is the following:
management decided last year that the store could afford to advertise more during the summer last year than it had in previous summers. Then, last year, Theall’s sales in the summer were stronger than in any previous summer. We see that the passage indicates that there was a correlation between an increase in advertising spending and an increase in sales. So, that correlation could be taken as indicating that the increase in sales can be attributed to the increase in advertising spending.
The correct answer will be the one such that determining what it mentions will weaken or strengthen the case for the conclusion.
(A) Whether by improving customer service Theall’s could have increased sales without spending more on advertisingDetermining this would not help with evaluating the case for the conclusion.
After all, information on whether Theall's COULD HAVE increased sales by improving customer service does not indicate whether the increase in advertising spending DID cause an increase in sales.
Eliminate.
(B) Whether the increase in Theall’s profits attributable to the increase in sales was greater than the increase in advertising spendingDetermining this would not help with evaluating the case for the conclusion.
After all, regardless of whether the increase in profits was greater than the increase in advertising spending, the increase in advertising spending could have caused the increase in sales.
If we were seeking to determine whether the increase in advertising spending paid off, this choice would be relevant, but that's not what we're seeking to determine.
Eliminate.
(C) What proportion of the increase in sales can be attributed to repeat customers spending more at Theall’s last summer than they spent the previous summerNot only new customers but also repeat customers can be influenced by advertising.
So, regardless of what proportion of the increase in sales can be attributed to repeat customers spending more, the increase in advertising spending may or may not have been the cause of the increase in sales.
Eliminate.
(D) How sales of other retail stores in Beach Haven last summer compared with their sales the previous summerThis choice is interesting.
After all, if sales of other stores in Beach Haven also increased, then it could be that the increase in Theall's sales can be attributed to some general factors that affected all stores in Beach Haven rather than the increase in advertising.
On the other hand, if sales of other stores did not increase, then we can be more confident that the reason for the increase in Theall's sales was the increase in advertising.
So, determining what this choice mentions would help with determining whether the increase in sales can be attributed to the increase in advertising spending.
Keep.
(E) Whether Theall’s sales for last summer were stronger than its sales for any other season last yearThis choice introduces an irrelevant comparison.
After all, what we're seeking to determine is whether the increase in advertising spending from the previous summer to the past summer was the cause of the increase in sales from the previous summer to the past summer.
We don't know anything about how advertising spending in the summer compares with that in other seasons. For instance, for all we know, Theall's increased advertising spending for all of last year.
Also, we have no idea how sales in the summer normally compare with sales in other seasons for Theall's.
So, information on how sales in the summer compared with sales in other seasons isn't useful for determining whether the increase in sales last summer can be attributed to the increase in advertising spending.
Eliminate.
