问题            Are responses to odors acquired as a function of the emotional context in
       which they are initially perceived? Researchers recently conducted a study in
       which a novel odor was paired with either a positive or negative emotional
Line    experience. Ratings associated with the test odor varied in accordance with the
(5)     paired emotion, such that the odor was perceived as either congenial or
       noisome, depending upon the quality of paired experience the participant had.
           Olfactory sensory attributes may produce an unlearned impact when odors
       are irritating; in these cases discomfort is experienced simultaneously to odor
       sensation, an event occurring when stimulation of the trigeminal nerve occurs
(10)    coterminous with olfactory sensation. Many odors elicit trigeminal stimulation
       to varying degrees, so that the subjective distinction between pure odor and
       trigeminal irritation is not possible to make, though scientists have precipitously
       ventured to suggest methods. While these cases may help explain why one may
       be immediately repelled by a certain scent, they unfortunately do not allow most
(15)    scientists to establish which smells trigger innate reactions.
According to the passage, which of the following can be inferred about the role of the trigeminal nerve in the experience of odors?
选项 A、The trigeminal nerve plays a much more significant role in the experience of an irritating odor than does actual olfactory sensation itself.
B、The trigeminal nerve produces a negative experience of an irritating odor independently of the emotional context in which the odor was initially perceived.
C、The trigeminal nerve tends to cause an experience of discomfort in the cases of odors that are initially paired with negative emotional experiences.
D、The functioning of the trigeminal nerve tends to be largely conditioned according to the pairing process simulated in the experiment.
E、The trigeminal nerve generally does not play a role in the experiencing of odors that create innate reactions.
答案B
解析
