Question
In the question below, a sentence is given with four
words highlighted in bold, followed by options that provide a replacement for each word. From the options, choose the word that must be replaced with its appropriate replacement. If all the highlighted words are correct and none need to be replaced, or if the incorrect word is not provided with an appropriate replacement, choose option (e), i.e. ‘None of the above’. The biggest asteroid impacts would have swathed our globe in recalcitrant rock vapour, boiling the oceans dry and fumigating the surface worldwide.Solution
The sentence tells us how the biggest asteroid impacts would have swathed (enveloped) our earth in rock vapour, boiling the oceans dry and fumigating (sterilizing) the surface worldwide (globally). RECALCITRANT means uncooperative and will not bear relevance here as the sentence uses it to describe rock vapour. It can be replaced with the given word INCANDESCENT which means emitting heat. Therefore, (b) is the right answer.
