| Blank |
|---|
| (A) sophistication |
| (B) retrenchment |
| (C) burgeoning |
| (D) resurgence |
| (E) curtailment |
| (F) expansion |
官方解說：
The words that fill the blank must convey that the field of ophthalmology experienced growth during the indicated period. The only choices that explicitly refer to growth are "burgeoning" and "expansion." While a "resurgence" would also be characterized by growth, there is no other answer choice that would produce a sentence with the same meaning.
Thus the correct answer is burgeoning and expansion.
