Select the most appropriate option to substitute the underlined word in the given sentence.
Pollution levels have increased so largely that they are almost killing us.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. highly.
Error is related to / concept: Wrong degree/intensity adverb used.
What is wrong: “Largely” means 'mainly' or 'mostly', not 'to a great extent' or 'intensely'.
Grammatical concept: To describe intensity or degree, use “highly”, not “largely.”
Correct phrase: Pollution levels have increased so highly
Final sentence: Pollution levels have increased so highly that they are almost killing us.
Hence, the chosen option is correct.
