Hi,
The answer is A) but I don't understand why it says "be compared" instead of should be or are...... Can anyone explain?
Since chromosome damage may be caused by viral infections, medical x-rays, and exposure to sunlight, it is important that the chromosomes of a population to be tested for chemically induced damage be compared with those of a control population.
(A) to be tested for chemically induced damage be compared with
(B) being tested for damage induced chemically are compared with
(C) being tested for chemically induced damage should be compared to
(D) being tested for chemically induced damage are to be compared to
(E) that is to be tested for chemically induced damage are to be comparable with |

The subjunctive mood introduced by "that the chromosomes..." needs
a verb form "be compared". Also, we have to use "compared with"
here since the objects being compared are similar.
B, C, D and E use incorrect "are compared", "to be compared" etc. |
