Answer 2

Answer:

The answer is "a".

I told him a thousand times not to repeat the mistake.

                Here we use the article "a" because thousand is a countable word and we use a before countable noun. "an" is also used before countable nouns but here the word thousand starts with the alphabet "t" which is a consonant. If the countable noun starts with a vowel we use "an".
