Fact 1: Television advertising is becoming less effective: the proportion of brand names promoted on television that viewers of the advertising can recall is slowly decreasing.

Fact 2: Television viewers recall commercials aired first or last in a cluster of consecutive commercials far better than they recall commercials aired somewhere in the middle.

Fact 2 would be most likely to contribute to an explanation of fact 1 if which of the following were also true?

(A) The average television viewer currently recalls fewer than half the brand names promoted in commercials he or she saw.
(B) The total time allotted to the average cluster of consecutive television commercials is decreasing.
(C) The average number of hours per day that people spend watching television is decreasing.
(D) The average number of clusters of consecutive commercials per hour of television is increasing.
(E) The average number of television commercials in a cluster of consecutive commercials is increasing.

Spoiler: :: OE
Because E indicates that the number of commercials in a cluster is increasing, it entails that proportionally more commercials are aired in intermediate positions. Hence, E helps fact 2 explain fact 1 by showing that increasingly more commercials are aired in positions in which viewers find them difficult to recall. E is the best answer.

A testifies to the ineffectiveness of television advertising but does not help fact 2 explain fact 1. B indicates that fact 2 contradicts rather than explains fact 1, since it suggests that the number of commercials per cluster is decreasing. C and D help to explain fact 1-by describing a change in viewing habits and a change in programming-but neither relates fact 2 to fact 1.

(A) The average television viewer currently recalls fewer than half the brand names promoted in commercials he or she saw.

This supports fact 1. It doesn't do anything for fact 2.

(B) The total time allotted to the average cluster of consecutive television commercials is decreasing.

If the total time is decreasing, then the chances of brand name commercials being in the middle is less. Does not support.

(C) The average number of hours per day that people spend watching television is decreasing.

Out of scope. Doesn't explain/support how brand names are not being recalled with their position in the cluster.

(D) The average number of clusters of consecutive commercials per hour of television is increasing.

if there are more clusters, then theres more chances for viewers to catch the first or last commercial in the cluster which could be brand names. Does not support

(E) The average number of television commercials in a cluster of consecutive commercials is increasing.

if the number of commercials in a cluster is increasing, then the chances for brand names to be in the middle is greater. This supports fact 2. Pick E

IMO:- E

Between D & E

Suppose In 1 hr movie, there are 4 ad breaks and each ad break there are 12 Nos ad. Therefore Total ads/movie aired are 4X12=48 Nos. Out of those 48 Nos, as per argument people would remember 2 ads/ breaks i.e. 2X4=8 Nos.

Now choice D says : Clusters /Ad breaks get increased. So ad breaks increased to 6 Nos. Now people would remember 2X6=12 Nos which is more than original 8 Nos. This is going against the argument.

Choice E :-Ads get increased.So now per ad break there are now 16 ads/break and 3 ad breaks.People would remember 2X3=6 Nos ads in this scenario which is going with the flow of argument which says that advertising is becoming less effective (Fact1)- Correct

(D)The average number of clusters of consecutive commercials per hour of television is increasing
Clusters of consecutive commercials could be small or big i.e. there could be 2 ads or 10 ads. We do not know that.
Also if the cluster of ads is increasing then there can be two scenarios:
1st: when the same ads are being repeated.
If this is the case, then it would reinforce the brand names because you will be watching the same brands again and again.

2nd: When ads are different everytime. It would become difficult to recall except what is seen first and last.

(E) The average number of television commercials in a cluster of consecutive commercials is increasing
If the number of ads increase in a cluster then it becomes hard to recall the clutter of brands. Thus it supports fact 1.

What E is clearly showing that because most people recall less during ads that appear in the middle, and because there are more of these clusters most will forget most of they saw and will probably only tend to remember brands advertised in the first and last ad of a cluster.

Fact 1
TA ==> less effective
less recall no of brands
Fact 2
first and last I remember, middle I forget.

(D) The average number of clusters of consecutive commercials per hour of television is increasing.
opposite effect.

(E) The average number of television commercials in a cluster of consecutive commercials is increasing.
if E is true, it can explain fact 1. more no. of consecutive commercial and more they forget.

C and D help to explain fact 1-by describing a change in viewing habits and a change in programming-but neither relates fact 2 to fact 1.

The clue to the answer lies in Fact 1- i.e. the proportion of $$\frac{# of Brand names viewer remember}{total brand advertised}$$ is decreasing

if # total brand advertised is increasing in a cluster ( as per fact1) then the denominator will increase. and this increase combined with Fact2 will validate the Fact 1.

So is the reason option D is wrong and option E is correct.

This question is to explain Fact1 with Fact2. But it can't be completely explained. What is worse? Fact2 says that only the head and tail can be remembered, and fact1 says that the proportion of ads that are remembered has dropped.
OK, think about it, the head and tail can remember, the decrease in the ratio indicates that the total number has become larger, so the number of advertisements that should be untenable is increasing, that is, the number of advertisements in the middle is increasing. That is the answer E.

Fact 1: Television advertising is becoming less effective: the proportion of brand names promoted on television that viewers of the advertising can recall is slowly decreasing.

Fact 2: Television viewers recall commercials aired first or last in a cluster of consecutive commercials far better than they recall commercials aired somewhere in the middle.

Fact 2 would be most likely to contribute to an explanation of fact 1 if which of the following were also true?

CATCH: an answer choice that contributes to the conclusion that promotion is less effective due to people not recalling advertisements in the middle of cluster.

(A) The average television viewer currently recalls fewer than half the brand names promoted in commercials he or she saw.
INCORRECT because if the viewer is recalling fewer than half, it still could be more than just the ones aired last or first.

(B) The total time allotted to the average cluster of consecutive television commercials is decreasing.
TRAP ANSWER. It is very possible that people do not recall because the time per advertisement has decreased. But we are not looking for a reason why "not recalling" happens.

(C) The average number of hours per day that people spend watching television is decreasing.
IRRELEVANT. We are concerned about viewership of commercials specifically.

(D) The average number of clusters of consecutive commercials per hour of television is increasing.

(E) The average number of television commercials in a cluster of consecutive commercials is increasing.
CORRECT. If the number of ads per cluster are more and people can recall only the ones at beginning and end, then the proportion of commercials recalled becomes less. Thus less effective promotion.

Option D---> fact 1 talks about the proportion of brand names that viewers of the advertising can recall. As per the above explanation, the proportion remains the same.
Original ratio = 8/48 = 1/6
New ratio =12/72 =1/6

So viewers recall the same proportion of brand names in case of D.

Fact 2: Television viewers recall commercials aired first or last in a cluster of consecutive commercials far better than they recall commercials aired somewhere in the middle.

If the total number of commercials in a cluster of consecutive commercials= N
Then, the proportion of advertisements that a viewer can recall far better than normal = 2/N

(E) The average number of television commercials in a cluster of consecutive commercials is increasing-- this tells that our denominator N is increasing. Thus it helps explains fact 1.
