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: In last 4 years use of X increased 73% among children. This increased no. is greate than increase in no. of adults using X in the same time period.
Lucy: Now, 11 adults per 1000 use X. Last year 6.6 children per 1000 used X.

A. Lucy does not say now usage level among children is high
C. Increase can be 73% in last 4 years. Lucy only says last year it was 6.6 Now 73% increase means, 7.3 increased per 1000. So, if 4 years back the rate was 2, now it can be 9.3. And also, 6.6 can very well stand in between 9.3 and 2.
D. No where this statement is mentioned.
E. Statement is not valid.

Now B says, This increase in 73% is not an indication that the usage is high.
Lucy said, 11 % is considered as normal. And if last year the rate was 6.6 among children, the rate cannot be more than 11% even with 73% increase. So, this rate is definitely normal.

This is what Antoine intends to say but not Lucy's conclusion.
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.
Lucy tries to say that the figure, based on which Antoine is arguing, that though the f% figure is higher among adults, it is indeed common. Thus, she concludes the consumption rate among teenagers are not so high as well.
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.
Here, Lucy precisely tries to contradict Antoines estimates which is not the case.It is unlikely that the increase in the use of antipsychotic medicines by children will continue at the same rate.
Out of context.If the number of children taking antipsychotic drugs is given as a certain number, the actual rate of such drug use is even higher.
This option tries to question the facts given by Antoine. Thus, not apprpriate.

Pranay
