Answer 2

Is there any milk left in the fridge?

• 'A', 'An', 'The' are defined as articles.
• 'The' is generally used to refer specific or particular things.
• It is also used to indicate particular one thing only.
• 'The' is also used to define superlatives.

Here, in this sentence, article 'the' is used to indicate a particular thing. The fridge is particular here. So, the article which will be used here is 'the'.

On the other hand, article 'a' or 'an' is generally used for non specific objects. They can also be used to indicate the number one.
