Directions: In the given sentence identify the segment which contains the grammatical error. When I met Akbar Padamsee, one of a pioneers of Indian art, he was 87 but still alert and active.

Explanation

The correct answer is "one of a pioneers of Indian art". Key Points In the given sentence, the use of the article ' a' before the specific noun 'pioneers' is incorrect . ' A' is an indefinite article , which means that it refers to, or introduce, an unspecified noun. In other words, we use an indefinite article in front of a noun when we're not referring to a particular person, place, thing or idea, but we want to convey that we're talking about any person, place, thing or idea. We use ' a' before a consonant sound (here surprising). In the given sentence, the noun ' pioneers ' is specific or particular . The definite article ' the ' is used before singular and plural nouns when the noun is specific or particular. Hence, the correct answer is option 4. Correct Sentence : When I met Akbar Padamsee, one of the pioneers of Indian art , he was 87 but still alert and active. Additional Information There are three articles: a, an, and the . Articles are used before nouns or noun equivalents and are a type of adjective.
