Answer 2

Articles are used before a noun. There are three articles 'a', 'an', and 'the'. When the noun begins with a vowel, 'an' is used otherwise 'a' and 'the' are used.

1. It was the proudest moment of my life. (proud - abstract noun)
2. Where did you put the keys? (keys - common noun)
3. Have you seen an elephant? (elephant - noun contains vowel 'e' as the first letter)
