Chorioretinitis is an inflammation of the eye that normally effects only small children, and it
usually can be treated with antibiotics.
A. effects only small children
B. effects small children ordinarily
C. affected small children
D. affects small children
E. affects only small children

OA E

I am confused with D and E

Can anyone explain me why not D is correct?

'only' is a boundary word. If u omit that, other age groups, although not equally likely, will have increased chances of getting affected by Chorioretinitis. Since, 'only' is explicitly given in the question sentence, you can't omit that.

Can you tell us the source of this question? Generally speaking, SC on the GMAT tests only grammar and meaning, and doesn't focus much on word choice. Unlike other tests, they almost certainly won't test you on accept/except, precede/proceed, etc. The only word choice issues tested are quantity words (FEWER v. LESS), and comparatives v. superlatives (LESS v. LEAST).

I have never seen a real GMAT question that tests the difference between AFFECT and EFFECT, so this is not a GMAT-like question.
