Scientist: My research indicates that children who engage in impulsive behavior similar to adult thrill-seeking behavior are twice as likely as other children to have a gene variant that increases sensitivity to dopamine. From this, I conclude that there is a causal relationship between this gene variant and an inclination toward thrill-seeking behavior.

Which one of the following, if true, most calls into question the scientist's argument?

A) Many impulsive adults are not unusually sensitive to dopamine.

B) It is not possible to reliably distinguish impulsive behavior from other behavior.

C) Children are often described by adults as engaging in thrill-seeking behvaior simply because they act impulsively.

D) Many people exhibit behavioral tendencies as adults that they did not exhibit as children.

E) The gene variant studied by the scientist is correlated with other types of behavior in addition to thrill-seeking behavior.

IMO the ans is D. Am split for choice between D & A really. But the conclusion really is that presence of gene leads to inclination to thrill seeking. D says that the behavior in adult is different than in childhood. So the the correlation between behavior in childhood and adult is no longer valid. options A,B,C dont talk of thrill seeking behaviour but impulsive behavior, a slight twist really!

KUDOS
Answer should be B.

A) Many impulsive adults are not unusually sensitive to dopamine.(The argument has not concluded anything about Adults.)

B) It is not possible to reliably distinguish impulsive behavior from other behavior.(Correct). If it is not possible to distinguish between impulsive and other behavior,The scientist's whole argument will come to an end as the domain itself will not be available to do the experiment)

C) Children are often described by adults as engaging in thrill-seeking behvaior simply because they act impulsively.(Argument doesn't have to do anything with adults' description)

D) Many people exhibit behavioral tendencies as adults that they did not exhibit as children.( Nothing to do with argument)

E) The gene variant studied by the scientist is correlated with other types of behavior in addition to thrill-seeking behavior.(This also has no effect on the argument)
