Question

Astronomers frequently observe mergers between distant galaxies, but it’s ________[I]_______ to reconstruct the interactions that defined the ________[II]_______ Milky Way in part because we lack an outside perspective of our own galaxy.

| [I]       | [II]         |
|-----------|--------------|
| (A) Trickier | (D) Influence |
| (B) Assiduity | (E) Modern |
| (C) Reprobate | (F) Devious |

Accepted Answer

**Solution:**

1. The word **Trickier** means something that is more difficult or complicated to handle, requiring careful skill or attention. This fits well in the first blank as reconstructing galaxy interactions is a complex task.

2. **Modern** means relating to the present or recent times, which suits the second blank describing the Milky Way in its current state.

3. Other options do not fit contextually:
   - **Assiduity** means constant attention, which doesn't fit the sentence structure.
   - **Reprobate** refers to a morally unprincipled person, irrelevant here.
   - **Devious** means using underhand tactics, which is unrelated to the context.
   - **Influence** could fit the second blank but does not pair well with the first blank choices.

Hence, the correct pair is (A) Trickier and (E) Modern, making option (c) the right answer.

**Answer:** (c) A-E
