Fill in the blank with the appropriate word.

Ancient cloud studies were not made in __________, but were observed in combination with other weather elements.

Correct option is B

Correct answer: B

Why

• The sentence contrasts studying clouds alone versus studying them with other weather elements.
• The phrase “not made in ________, but were observed in combination with…” clearly needs a word that means “separately/alone.”
• The standard and correct collocation is “in isolation,” which fits both grammar and meaning.

Correct answer word – isolation
Hindi meaning: अलगाव
Example: The experiment was not conducted in isolation; it was compared with earlier results.

Meanings of other options

• Accompanied – Went along with (साथ होना)
• Group – समूह (but “made in group” is not a correct collocation; it would need “in a group” and still wouldn’t match the contrast as precisely as “in isolation”)
• Wholesome – Healthy; good (स्वस्थ/अच्छा)
