GATE 2022 IN GA Q.1: solution and answer

Official answer: CSource: Official answer key, GATE 2022 IN (IIT Kharagpur)

1. First blank: a noun. It follows the adjective burning ("a burning ______"), so it names the thing on fire: the rubber ring fitted around a wheel. In Indian and British English, which the paper follows, that noun is spelt tyre. American English spells the same noun tire, so the first blank alone does not settle the answer. The second blank does.

2. Second blank: a verb. It follows the modal could, and a modal takes the base form of a verb ("could ______ you"). So the blank needs a verb that can take the object you and make sense.

3. Test each candidate for the verb slot. tire (verb) means to make someone weary or exhausted, so "could tire you quickly" makes sense. tier is a noun meaning a row or level, as in "a three-tier cake". Its rare use as a verb means to arrange things in tiers, which cannot apply to you. tyre is a noun for the wheel's rubber ring, and no sense of it gives "could tyre you quickly" any meaning.

4. Eliminate options. (A) and (D) put tier in the verb slot, and (B) puts tyre there, so none of the three makes sense. Only (C) puts the verb tire in the second blank.

5. Check the whole sentence. "Inhaling the smoke from a burning tyre could tire you quickly." The noun and the verb are both used correctly, so the answer is (C).
