Among people experience migraine headaches, some experience what doctors call "common" migraines, whereas others experience "classical" migraines. Siblings and spouses of common migraine sufferers are themselves twice as likely as the general population to experience common migraines. Siblings of classical migraine sufferers are four times more likely than the general population to experience classical migraines, whereas spouses of classical migraine sufferers are no more likely than the general population to experience such headaches.

The information above provides the most support for which of the following hypotheses?

(A) Susceptibility to classical migraines is more dependent on hereditary factors than is susceptibility to common migraines.
(B) Unmarried adults are more likely to suffer from classical migraines than they are to suffer from common migraines.
(C) People who do not experience migraine headaches are unlikely to have spouses who are migraine headache sufferers.
(D) Children of people who suffer from common migraines are more likely than the general population to experience a common migraine.
(E) Between one-quarter and one-half of the general population suffer from either common or classical migraine headaches.

The correct answer is A. Here is why:

When I started to read this stimulus, I can tell that the author wants you to make distinction between siblings and spouse. The first sentence doesn't really help but the key to this question is the last sentence. There's a distinction and comparison between siblings of classical migraine sufferers and spouse of classical migraine sufferers. Author posits that siblings of classical migraine sufferers are four times more likely than general population to experience classical migraine. On the other hand, spouse of classical migraine sufferers are no more likely than general population to experience classical migraine. If you understand this then it should be clear why A is correct. A is synonymous to the last sentence of the passage, the author just puts it in a different or perhaps more convoluted way to catch the test takers.


Why D is incorrect? The prompt only talks about siblings (brother & sister) and spouses (husband/wives) of the migraine sufferers. The author never talk about children of migraine sufferers, therefore choice D could be true but not must be true. We need more information. However, answer choice A must be true, this is why A is correct.

D)Children of people who suffer from common migraines are more likely than the general population to experience a common migraine.
E)Between one-quarter and one-half of the general population suffer from either common or classical migraine headaches.


A is very straightforward here. Since classical migraine affects the siblings too, it shows that it's genetically linked.

B)Unmarried adults are more likely to suffer from classical migraines than they are to suffer from common migraines. (stem does not differentiate unmarried and married adults so this is not relevant)
C)People who do not experience migraine headaches are unlikely to have spouses who are migraine headache sufferers. (stem does not talk about it)
D)Children of people who suffer from common migraines are more likely than the general population to experience a common migraine. (again the stem does not say anything like this)
E)Between one-quarter and one-half of the general population suffer from either common or classical migraine headaches.
There is nothing in the stem from which we can infer this


IMO A is the answer . i arrived at my answer by chosing POE

To me both A & D sound right, but as D doesnt include classical migraine in it, A seems to be a more inclusive answer and hence better.

Will go with A....since this is a hypotheses and not a support question ...in which case it could have been D.

GO with A. THe passage supports only A and I'd be suprised if I'm wrong on this one. Thanks!

I was doubting between A and D.
Finally I choose D....the wrong one!
Can anybody explain why this one cannot be the right answer?

Thank you so much for the explanation.
In fact my mistake came from the word siblings. I was not very sure about the meaning and though that it includes the children as well as some other members of the family of one person. Now it's very clear for me why the answer is A.
Thanks again!

Got A from POE. I guess whatever works. All others may very well not hold.

Hi,

We can use the Kaplan denial test to prove that A must be true (and therefore correct) and that D could be false (and therefore incorrect):

If A were untrue--if susceptibility to classical migraines WAS NOT more dependent on hereditary factors--then there would be no available explanation for the discrepany in likelihood of genetic transmission, and thus that discrepancy could not exist, and thus a part of the passage would become falsified. But in an inference question every part of passage is necessarily true. Thus, choice A must be true.

On the other hand, choice D could be false without falsifying any part of the passage (primarily because the passage did not establish anything that had to be true about "children"--"children" are outside the scope).

TAKEAWAYS:
--we can use the Kaplan denial test in inference questions (many people think it can only be used in necessary assumption questions).
--the correct answer will always be very CLOSE to the passage (notice that every idea of choice A is discussed in the passage either explicitly or implicitly); converesely, facts about "children" cannot be inferred from the text of the passage.

choice A is best.

other options are irrelevent to the argument.

chose D without checking whether children have been mentioned in the passage or not..
An easy question though..

Let x be a number of counts of migraine

General populace: x

Common migraine: Sib=2x; Spouse=2x

Classical migraine: Sib=4x; Spouse=x

From above statistics, we can infer that
brothers & sisters of classical sufferers have 4x chances whereas
brothers & sisters of common sufferers have 2x chances
Because brothers & sisters (siblings) are related by blood, we can
say that hereditary factor play a major role in acquiring classical migraine
than in common migraine.
This is the position of option A.

On the other hand, spouses of common migraine have 2x chances whereas
spouses of classical migraine have x chance
From the statistics, Spouses of common migraine are more prone than are
those of classical migraine.
However, this is not discussed in any of the options.


Do I make any sense or am I over stating what is meant in the stem?

Quite straightforward. It's A. My reasons for choosing this is as follows:

(A) Susceptibility to classical migraines is more dependent on hereditary factors than is susceptibility to common migraines. [Correctly identifies support to the premise and the major part of the passage states the instances for this]
(B) Unmarried adults are more likely to suffer from classical migraines than they are to suffer from common migraines. [There is nothing in the passage that suggests how vulnerable unmarried adults will be]
(C) People who do not experience migraine headaches are unlikely to have spouses who are migraine headache sufferers.[Again, out of scope]
(D) Children of people who suffer from common migraines are more likely than the general population to experience a common migraine.[Out of scope, also]
(E) Between one-quarter and one-half of the general population suffer from either common or classical migraine headaches.[Out of scope]

Common migraine in SIBLINGS and SPOUSES get = 2 x Common migraine in GENERAL POPULATION

Classical migraine in SIBLINGS = 4x classical migraine in GENERAL POPULATION = 4 4x classical migraine in SPOUSES

A is exactly correct, stating the premise in the argument.

A)Susceptibility to classical migraines is more dependent on hereditary factors than is susceptibility to common migraines.

From the premises given, A must be true. Others may be real-world-true or may be true according to the premises. But they may not necessarily be true.
