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?

The current level of antipsychotic drug use in children is abnormally high.

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.

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.

It is unlikely that the increase in the use of antipsychotic medicines by children will continue at the same rate.

If the number of children taking antipsychotic drugs is given as a certain number, the actual rate of such drug use is even higher.

Antonie - Nos of Children taking medicine increased more than that of adults. He means that 'it is alarming'
Lucy - Though nos of adults taking has not increased, current rate is normal. In contrast (note that contrast word), children taking medicine is 6.6....meaning its high

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. (opposite of what is mentioned by using contast word)

IMO A

I think answer has to be B...
The argument does use the word in contrast... adult consumption rate is normal. In contrast, the same rate for children in fact is low, which is clear in the given statistics (6.6 vs 11) That is why the in contrast is used.
I think the most important word in this argument is BUT at the start of L's argument.
That is where you come to know that the contrast is about to be presented....
If you select option A, then L would argue with what A is saying... N that is surely not the case as indicated by the contrast word BY.

(A) Lucy's states that the rate of adults taking antipsychotic drugs is normal, and the rate of children taking such drugs is even lower. hence we can not conclude that the current level of antipsychotic drug use in children is abnormally high.

(B) CORRECT. the conclusion to which Lucy's argument is leading.

The answer cannot be A... Lucy is trying to refute Antoine's conclusion. A leans towards supporting Antoine's conclusion. C is not correct, because it is definitely possible to have a 73% increase to 6.6 per 1000. D isn't stated anywhere in the prompt. E isn't either.

The answer thus has to be B.

Have you wondered how you could have found such a treasure? -T
