Fill in the blanks:
The witness’s statement added ___ to the investigation and ultimately helped to ___ the mystery surrounding the case.

Correct option is B

The correct option to fill in the blank is (b) clarity, solve.
Explanation:
· Clarity (noun): the quality of being clear and easy to understand (स्पष्टता)। The witness’s statement made the situation clearer.
· Solve (verb): to find an answer to a problem (समाधान करना)। The witness’s input helped in finding the truth.
Why this fits: A witness providing clear information helps in solving a mystery. The pair of words forms a natural and logical sequence in investigative contexts.
Grammatical Rule (English): Maintain logical subject–verb–object alignment. Use nouns like "clarity" with "add," and "solve" with "help" for action outcome.
Grammatical Rule (Hindi): “Clarity” एक संज्ञा है जिसका अर्थ है स्पष्टता और “solve” एक क्रिया है जो किसी समस्या का समाधान बताता है।
Meanings of the other options:
· (a) Confusion – a state of disorder or uncertainty (उलझन), deepen – to make worse (बढ़ाना).
· (c) Ambiguity – unclear meaning (अस्पष्टता), escalate – to intensify (बढ़ जाना).
· (d) Evidence – proof (सबूत), delay – to postpone (देरी करना) – delays solving, not logical here.
