Question

That man carried an umbrella with him yesterday.
a. True
b. False

Answer 1

Hint: We use indefinite articles when the identity of an object is unknown (or general & not specific). There are two kinds of indefinite article one used before a word starting with the vowel sound (we use - an) and the other with the remaining alphabets (we use - a).

Complete answer:
First let us understand what are articles - they are modifiers for nouns and have two types - Definite and indefinite, ‘the’ is the definite article and is used to refer to specific or particular nouns; whereas, ‘a/an’ are the indefinite articles used to modify non-specific or non-particular nouns.
Now, you must understand the usage of the indefinite article. So –
As discussed earlier Indefinite articles refer to non-specific nouns. Such as – I need a pen or I want an ice-cream. In both the examples as you can see we are not referring to a specific pen or ice-cream, the indefinite articles are communicating the fact that you'd accept any pen or ice-cream.
They are of two types – a & an. Now let us understand the usage of a & an, ‘an’ is used before a word that starts with a vowel sound and ‘a’ is used before words starting with other alphabetical sounds.
So, in the sentence above we can see the words – an umbrella. Since, an umbrella starts with a vowel sound the indefinite article ‘an’ is used before it.
Therefore, the correct option I – ‘a’ – true, i.e. in the given sentence an indefinite article is given.

Note: You must keep your concept clear between the two types of articles and not mix up definite articles with indefinite articles.
