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 suferers are no more likely than the general population to experience such headaches.

Type - Inference
Boil it down - Common migraine - Siblings and spouses have 2x probability of suffering
Classical migraine -Siblings have 4x probability of suffering
Pre-Thinking - the hereditary link is an important factor in classical migraine

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. Correct answer
(B) Unmarried adults are more likely to suffer from classical migraines than they are to suffer from common migraines. May or may not be true
(C) People who do not experience migraine headaches are unlikely to have spouses who are migraine headache sufferers. Out of scope
(D) Children of people who suffer from common migraines are more likely than the general population to experience a common migraine. May or may not be true as children have not been talked in the argument
(E) Between one-quarter and one-half of the general population suffer from either common or classical migraine headaches. Out of scope
