I. On the global stage, India has a vital role in curbing climate change and catalysing action by other countries.
II. A year from now, citizens of the US will vote in what perhaps will be one of the most importance polls in America’s history.
III. The pattern of growth matters of reduction of poverty.

Q: Answer-&lt;p&gt;I. On the global stage, India has a vital role in curbing climate change and catalysing act...

Sentence II is incorrect as the sentence needs a noun instead of an adjective, hence, lsquoone of the important pollsrsquo is correct usage. Sentence III is incorrect as the correct preposition that should be used in the passage is ldquo for reductionrdquo instead of ldquo of reductionrsquo because lsquoforrsquo indicates lsquobecause ofrsquo.
