Answer:
An animal
A banana
An accident
A teacher
A school
Explanation:
"A" and "An" are articles, which are a class of words that specify a noun within a sentence. Knowing when you will use "a" or "an" is very simple and you will only need to look at the first letter of the word that is written after these articles. If this word starts with a consonant, you must use the article "a," if the word starts with a vowel, you must use the article "an."
