Option A: There seems to be a broad range of international policy issues on which the views of France’s Socialist president
are more compatible with President Reagan’s than
were those of his predecessor. Correct.
In option A, the views of France's Socialist president on international policy issues are more compatible with President Reagan's (i.e. the views of President Reagan) than those of his predecessor were [compatible with the views of President Reagan]. It can be seen that two comparisons are made and there is no ambiguity about what the comparisons are about, and what two elements are being compared. On one hand, is a comparison between the views of the current French Socialist president and the views of President Reagan on international policies. On the other hand, is a comparison between the views that the predecessor of the current French president had on international policies and the views of president Reagan on international policy. The meaning is clear and unambiguous. Keep A.
Option B: There seems to be a broad range of international policy issues on which the views of France’s Socialist president
are more compatible with those of President Reagan’s than
were those of his
predecessor’s. Option B has a double possessive error. Except for the double possessive error, option B is identical to option A. Eliminate B, keep A.
Option C: There seems to be a broad range of international policy issues on which the views of France’s Socialist president seem more compatible with those of President Reagan than [
were] his predecessor’s. Without
were, there is ambiguity in the comparison. The first part of the comparison is okay. The views of the current French president on international policies are compared with the views of President Reagan. In the second part of the comparison, it is not clear whether the views of current French president are compared with the views of his predecessor or that the views of the predecessor are compared with the views of President Reagan. Eliminate option C.
Option D: There seems to be a broad range of international policy issues on which France’s Socialist president’s views are more compatible with President Reagan’s than [
were] his predecessor’s. The same ambiguity in option C exists in option D because of the omission of
were in the sentence. Eliminate option D.
Option E: There seems to be a broad range of international policy issues on which France’s Socialist president’s views seem more compatible with President Reagan’s than [
were] those of his predecessor. The same ambiguity issue with the second part of the comparison in options C and D exists in option E as well. The sentence would have been clearer if
were is inserted.
The right answer is therefore option A.
