Solution (By Examveda Team)
In the given sentence "No zoologist is able to keep a gorilla under close observation in the dark jungles in which he had been living," the most appropriate words to fill in the blanks are "is" and "had been living.""No zoologist is able to keep a gorilla under close observation" - The verb "is" is in the present tense, and it indicates a general truth or fact about the current situation.
"in the dark jungles in which he had been living" - The phrase "had been living" is in the past perfect continuous tense and indicates a past action that was ongoing before another past action. In this context, it refers to the gorilla living in the dark jungles before the observation took place.
The other options do not use the correct verb forms for the given sentence. Option A, "was/lived," uses the simple past tense for both verbs, which does not convey the correct sequence of events. Option B, "will/will live," uses the future tense for both verbs, which is not suitable for describing past events. Option C, "had been/has lived," uses the past perfect continuous tense and the present perfect tense, but they do not match the context of the sentence. Option E, "has been/lives," uses the present perfect continuous tense and the simple present tense, which also do not fit the context.
Therefore, the correct answer is "D. is/had been living.

To determine the most appropriate words to fill in the blanks in the sentence "No zoologist . . . . . . . . able to keep a gorilla under close observation in the dark jungles in which he . . . . . . . ..," let's analyze each option:
1. **A. was/lived**
- "No zoologist was able to keep a gorilla under close observation in the dark jungles in which he lived."
- This combination is correct and makes sense because it uses the past tense for both verbs, indicating that both actions happened in the past.
2. **B. will/will live**
- "No zoologist will be able to keep a gorilla under close observation in the dark jungles in which he will live."
- This combination uses the future tense, which is less appropriate for the given context, as it implies a situation entirely in the future, which seems unlikely for a historical statement.
3. **C. had been/has lived**
- "No zoologist had been able to keep a gorilla under close observation in the dark jungles in which he has lived."
- This combination mixes past perfect with present perfect, which is awkward and incorrect for the given context.
4. **D. is/had been living**
- "No zoologist is able to keep a gorilla under close observation in the dark jungles in which he had been living."
- This combination uses present and past perfect continuous, which is grammatically awkward and confusing.
5. **E. has been/lives**
- "No zoologist has been able to keep a gorilla under close observation in the dark jungles in which he lives."
- This combination uses present perfect and present simple, which could make sense if we are talking about an ongoing situation. However, it slightly changes the meaning to indicate that up to the present, no zoologist has managed to do this.
The best choice for conveying a clear, past situation is:
**A. was/lived**
So, the completed sentence is: "No zoologist was able to keep a gorilla under close observation in the dark jungles in which he lived."
