### HideShow timer Statistics

In a trial, two groups of people were shown images containing either happy faces or sad faces. Thereafter, both
groups were all offered champagne. Those who had seen images with happy faces drank twice as much as those
who had seen images with sad faces. This suggests that advertising champagne using images with happy faces
would be an effective way to increase sales.

In order to evaluate the strength of the argument above, it would be most helpful to run a similar experiment that

A. compared the effect of viewing happy images without faces to that of viewing sad images without faces
B. measured the consumption of various wines other than champagne subsequent to the showing of other types of
facial expressions
C. asked both groups how they felt after seeing the images and drinking the champagne
D. used champagne advertising images without faces in place of the images with sad faces
E. measured the correlation between the groups’ perceptions of how happy they were at the beginning of the trial and
how much champagne they thought they drank

The conlcusion in argument is "
"advertising champagne using images with happy faces would be an effective way to increase sales"

We know from the experiment that consumption after seeing happy faces was more than consumption after seeing sad faces. But to conclude that 'happy faces would be effective' is to assume that happy faces increased the consumption, while there is a possiblity that happy faces did not increase the consumption rather sad faces decreased the consumption.

Experiment listed in option D is the only one which would help us determine whether happy faces 'increase' the consumption or not.

Ans D it is!

I guess its C.
If sad ppl feel happy after drinking, they feel better and increases the sales..
If sad ppl dont feel better after drinking, no increase in sales.

Experts please clarify.. Lot of room for discussion.. 3 ppl.. 3 diff answers till now..

I will go with E.
As E says that something else (other than advertising) could be the reason for increased alcohol consumption.

Should be E. Other option doesn't help to strengthen the argument.
