2) D

A -Wrong

This statement makes a correlation between long term use of antidepressant drugs and worse outcome for patients. However, this correlation is false as the text does not suggest that the patient’s condition becomes worse.

B -Wrong

Although this may be a correct statement, we cannot infer from the text that doctors are being advised to do so.

C -Wrong

There can be other reasons for the increase in th e number of patitents (e.g. increase in population). So we cannot conclude that antidepressant drugs are not effective in the long term.

Also the word ‘clearly’ is too strong.

D -Correct

This statement uses the appropriate words and summarises the text completely. ‘Provides no evidence’ suggests that the statement neither concludes that long term term health is improving nor does it say that long term health is not improving.
