Warning! This is one of the five hardest LSAT questions I have ever seen. Those who wish to keep a sane mind, please do not continue reading this question. If you wish to torture yourself, I cannot stop you.

In one study, hospital patients' immune systems grew stronger when the patients viewed comic videos. This indicates that laughter can aid recovery from illness. But much greater gains in immune system strengthen occurred in the patients whose tendency to laugh was greater to begin with. So hospital patients with a greater tendency to laugh are helped more in their recovery from illness even when they laugh a little than other patients are helped when they laugh a greater amount.

The argument is most vulnerable to criticism on the grounds that it:

(A) Overlooks the possibility that the patients whose tendency to laugh was greater to begin with laughed more at the comic videos than did the other patients

(B) Fails to address adequately the possibility that the patients whose tendency to laugh was greatest to begin with already had stronger immune systems than the other patients

(C) Presumes, without providing justification, that hospital patients have immune systems representative of those of the entire populations

(D) Takes for granted that the gains in the immune system strength did not themselves influence the patients' tendency to laugh

(E) Presumes, without providing justification, that the patients whose tendency to laugh was greatest to begin with recovered from their illnesses more rapidly than the other patients

The question is a bit tricky but elimination helps in being confident about (A).

Hospital patients' immune systems grew stronger when the patients viewed comic videos. This indicates that laughter can aid recovery from illness.
But much greater gains in immune system strengthen occurred in the patients whose tendency to laugh was greater to begin with.

Conclusion: Hospital patients with a greater tendency to laugh are helped more in their recovery from illness even when they laugh a little than other patients are helped when they laugh a greater amount.

The conclusion is a bit out there. The argument just says that watching comic videos helps immunity grow. But it helped those people more whose tendency to laugh was more in the beginning (presumably because they laughed more while watching the video).

Then the conclusion confuses us with "if tendency to laugh is high, even if one laughs less than others, one recovers more"

Let's look at options (B) to (E) first:

(B) Fails to address adequately the possibility that the patients whose tendency to laugh was greatest to begin with already had stronger immune systems than the other patients

Definitely not true. We are talking about "gains in immune system". Even if their systems were better to begin with, we need to look at improvement only.

(C) Presumes, without providing justification, that hospital patients have immune systems representative of those of the entire populations

Definitely not true. The argument talks about hospital patients only. It does not conclude about entire population anyway.

(D) Takes for granted that the gains in the immune system strength did not themselves influence the patients' tendency to laugh

Not true. The argument talks about "tendency to laugh was greater to begin with". So the study measured the "tendency to laugh" in the beginning and then saw what kind of improvements were obtained. What happened to their tendency to laugh after gaining immune system strength is irrelevant.

(E) Presumes, without providing justification, that the patients whose tendency to laugh was greatest to begin with recovered from their illnesses more rapidly than the other patients
The argument gives justification : But much greater gains in immune system strengthen occurred in the patients whose tendency to laugh was greater to begin with.
It tells that people whose tendency to laugh was more had greater gains in immune system strength. Hence it does not presume without justification.

Now let's look at (A).

(A) Overlooks the possibility that the patients whose tendency to laugh was greater to begin with laughed more at the comic videos than did the other patients

Correct. We are not given in the argument that people with higher tendency to laugh laughed little. It is logical that those with higher tendency to laugh actually laughed more. But the conclusion overlooks this.

Answer (A)

OA is A, since people with a higher tendency to laugh can only be detected when laughing more/a lot, but not "little".

I was torn between A and D as well. Reason for eliminating D:
The sequence of events mentioned in the argument: Higher tendency to laugh -> Exposed to comic videos -> stronger immune systems.
If we consider option D, then the sequence becomes Stronger immune system -> Higher tendency to laugh -> exposed to comic videos. Thus, since the immune system was already strong to begin with, it would not show up as getting stronger after they were exposed to comic videos.

The question separates the two groups without any explanation.
The group that has tendency to laugh could be contained inside the group that watched comic videos...

Answer (A)


VeritasKarishma

I still find this question confusing.
Can you please explain only why option A is correct ?
I am explaining my understanding here. Really hard question.

Because " Hospital patients' immune systems grew stronger when the patients viewed comic videos " , the argument concludes that " laughter can aid recovery from illness."
Then the argument tries to prove this conclusion wrong saying "much greater gains in immune system's strengthening occurred in the patients whose tendency to laugh was greater to begin with."
and finally arrives at the conclusion that
"Hospital patients with a greater tendency to laugh are helped more in their recovery from illness even when they laugh a little than other patients are helped when they laugh a greater amount. "

But the argument can not arrive at the conclusion that it's the "greater tendency" that helped and not just 'laughter'.

If the patients with greater tendency to laugh at the beginning , laughed more at the comic videos than did the other patients then it's the 'laughter' that helped and not the 'tendency at the beginning".

The argument overlooks this.

Option A states this.

Not sure whether my understanding is correct.
