Question

i want to buy........ washing machine. i like......... one on tv yesterday​

Answer 1

Explanation:

I want to buy a washing machine. I like the one on TV yesterday

Answer 2

"a" and "the".

For the first example , we see the sentence mentioning a washing machine.

This mention of the word "washing machine" occurs for the first time in the sentence and as it is not part of a paragraph, this is the first mention we know.

Hence due to the first occurence of the word, we will use "a".

As the washing machine on the tv is mentioned and that washing machine has been mentioned specifically.

We will use the in the second blank as the washing machine that the person saw on the tv is specific and not "a".

Hence the answers.
