The rise in the Irrawaddy dolphin (1) in Chilika can be attributed to the eviction of (2) fish enclosures. After thousands of hectares of Chilika lake were made (3) free, Irrawaddy dolphins found unobstructed area for movement. (4), due to the COVID-19 lockdown last year, there were comparatively fewer tourist boats on Chilika lake, which made it (5) for dolphins to move from one part of the lake to another.

Show answer & explanation
Correct answer: D
Concept: Sentence connectors either continue the same line of thought (addition — moreover, furthermore, in addition) or reverse it (contrast — however, nevertheless, whereas, but, yet). Picking the right connector means judging first whether the next clause supports the previous idea or opposes it.
Application: The sentence just before blank 4 says removing the fish enclosures gave the dolphins an unobstructed area to move in. The blank-4 sentence adds a second, independent reason for easier movement — fewer tourist boats on the lake because of the COVID-19 lockdown. Both statements point in the same direction — more favourable conditions for dolphin movement — so the missing connector must signal addition, not contrast.
Cross-check:
Nevertheless and However both flag a concession or contradiction; they would fit only if the fewer-boats detail worked against the earlier statement, which it does not.
Whereas requires a paired contrast construction inside one sentence — "Whereas A, B" — with a clear opposing clause following it; that paired structure is not what this blank supplies.
The connector needed here signals a further point in the same supporting direction as the sentence before it — addition, not contrast.
Result: Moreover is the connector that correctly signals this addition.
