A. In spite of epidemic at Marine beach, there was little effect on tourists who visited country X.
B. The influx of tourist is normally high in months after August as compared to rest of the year.
C. There were few cases of drowning in Juhu beach in the month of August this year.

Official Solution:


Marine and Juhu beach, 5 miles from each other, are the two top beaches in country X. After recent epidemic at Marine beach in August, two months back, the influx of tourists in Juhu beach has increased when compared to same time in earlier years. It can, therefore, be concluded that this increase of tourists in Juhu beach is directly related to the epidemic in Marine beach.

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


A. In spite of epidemic at Marine beach, there was little effect on tourists who visited country X.
B. The influx of tourist is normally high in months after August as compared to rest of the year.
C. There were few cases of drowning in Juhu beach in the month of August this year.
D. Few of the much awaited tourist attractions have been opened in last three months in the three top beaches of country X.
E. Although the two beaches are just 5 miles, there has been no reported case of disease from area around Juhu beach.


A. The argument is about the visitors in Juhu beach, not about total visitors in country X.

B. The passage states that the visitors to Juhu beach this year is higher than that last year (during the same time). That in general the no. of visitors in August is high does not explain or refute the difference between the numbers in two years.

C. The conclusion of the passage is that the increase in number of visitors is the effect of epidemic in marine beach. Number of drownings in Juhu beach does not affect this causal relation.

D. Correct. If the conclusion is that X causes Z, then weakening statement would be something else Y causes Z, since this statement gives reason to doubt the conclusion: Y, not X causes Z. Here X = Epidemic in Marine beach, Z = increase in visitors in Juhu beach, and Y = opening of other tourist attractions.

E. The reasoning is same as that in option C: this statement does not oppose the causal relation.

D: Few of the much awaited tourist attractions have been opened in last three months in the three top beaches of country X.

But, this option is not explicit about the cause and effect and it applies to juhu as well as marine.

Please help me with the strategies that should be applied in cause and effect scenarios.

There are 4 broad types of cause and effect questions that are very frequent in GMAT:

Premise: X and Y are observed to happen together
Conclusion: X causes Y

Reversed logic:
Type 1: Strengthen: Y does not cause X.
Type 2: Weaken: Y causes X.

3rd factor:
Type 3: Strengthen: Z does not cause Y.
Type 4: Weaken: Z causes Y.

This question is of type 4.

When u said 4 types.. ie the type 1,2,3,4 you have mentioned.
But there are 3 categories of cause and effect arguments, right?

1)Premise: X and Y are observed to happen together
Conclusion: X causes Y

2)Reversed logic:

3) 3rd factor

Am I right in my understanding?

Thanks in advance.

No, what I mean is that the passage will be in the structure (1), i.e.
Main passage:
Premise: X and Y are observed to happen together
Conclusion: X causes Y

THEN comes the question, which may be a strengthening type (reversed logic OR 3rd factor) or weakening type (reversed logic OR 3rd factor).

So for the same passage (Premise-conclusion), there can be 4 types of question:
1. strengthening reversed logic
2. strengthening 3rd factor
3. weakening reversed logic
4. weakening 3rd factor

I have the same doubt. Can any of the experts answer this?

Also, lets the say option C "There were few cases of drowning in Juhu beach in the month of August this year" , was phrased like this:
"There were fewer cases of drowning in Juhu beach in the month of August this year"


Then which answer would be more preferable/ more accurate ? Would C be a better option then?

The only reason I didn't select this option was the word "few"

Few is a negative word which means "hardly any", as opposed to a few , which means "some"

Hence in GMAT rc and cr questions, should we not care about a few and few?

This is never tested on the gmat?

Sub-Standard Question:

Few itself is negative and it is mentioned that the top three beaches have been upgraded. Marina falls in that category, so if all three got upgraded equally why Marina is not getting the tourists? It is kinda strengthening the conclusion. More clarity on this question and the answer choice would be helpful.

Bump on this question -- can someone provide insight as to why D is correct? If the top three beaches all got new tourist attractions why would Marine and Juhu, which are the two top beaches, not also benefit from this upgrade?

Took me a while to reason this through but I think I figured it out! (I'll try to keep this short and simple)

The argument reasons that the increase in attendance at Juhu Beach can be attributed to the incident at Marine Beach. Basically, people heard about the incident at Marine Beach and went to Juhu Beach instead.

We have to weaken this reasoning by identifying another factor that can be attributed to the increase in attendance.

Option D offers another factor. Option D talks about 'much awaited tourist attractions' being opened at all three of the top 3 beaches. AHA! Since the tourist attractions were 'much awaited' (meaning people really wanted to go to them) and all 3 top beaches opened some, we have another reason why the attendance at Juhu Beach could have increased. Therefore, Option D provides an alternative explanation to the incident causing the increase in attendance.

Let me know if it helps!

I read all the comments, but I still don't understand the answer choice D. The fact that lot's of people expected new attraction is all 3 beaches, means, that the number of people had to be increased in all 2 beaches, so in the 2 of them, we are talking about and the third one. However, this answer does not weaken the author's conclusion. Because he states that due to Y, there is x. The answer В provides Z which is common for all the beaches, so it can only mean the overall increase in all beaches. However, the statement X is still in force. I mean that Z - is only a catalyst of increase, but it doesn't affect the authors conclusion, and thus can't weaken it.
