题目信息

Antoine: The alarming fact is that among children aged 19 years and younger, the number taking antipsychotic medicines soared 73 percent in the last four years. That is greater than the increase in the number of adults taking antipsychotic medicines during the same period.


Lucy: But the use of antipsychotic drugs by adults is considered normal at the current rate of 11 adults per 1,000 taking the drugs. In contrast, the number of children on antipsychotic medication last year was 6.6 per 1,000 children.


Lucy's argument is structured to lead to which of the following as a conclusion?

A:The current level of antipsychotic drug use in children is abnormally high.
B:The fact that the number of children taking antipsychotic medicines increased 73 percent over the last four years is not an indication that the current level of use is abnormally high.
C:If only 6.6 out of every 1,000 children are taking an antipsychotic medication, the increase in the use of such medicines cannot be the percentage Antoine cites.
D:It is unlikely that the increase in the use of antipsychotic medicines by children will continue at the same rate.
E:If the number of children taking antipsychotic drugs is given as a certain number, the actual rate of such drug use is even higher.

正确答案: B:The fact that the number of children taking antipsychotic medicines increased 73 percent over the last four years is not an indication that the current level of use is abnormally high.

Antoine --> AP drug consumption by children below 19 years increased by 73% in last 4 years.


Lucy --> Normal consumption is 110/10000. Last year consumption = 66/10000 .


Question: Lucy’s argument is structured to lead to which of the following as a conclusion?


A.The current level of antipsychotic drug use in children is abnormally high. - Incorrect. Opposite.


B.The fact that the number of children taking antipsychotic medicines increased 73 percent over the last four years is not an indication that the current level of use is abnormally high. - Correct. Even if the consumption rate increased by 100%, it's still closer to the normal consumption rate and not abnormally high. So 73% increase over 66/10000 is closer to 110/10000.


C.If only 6.6 out of every 1,000 children are taking an antipsychotic medication, the increase in the use of such medicines cannot be the percentage Antoine cites. - Incorrect. Opposes the stated facts.


D. It is unlikely that the increase in the use of antipsychotic medicines by children will continue at the same rate. - Incorrect. Out of scope.


E. If the number of children taking antipsychotic drugs is given as a certain number, the actual rate of such drug use is even higher. - Incorrect. Out of scope. Cannot be inferred.
