Answer 1

Answer:

*a*hint to solve the problem

Answer 2

Answer:

The teacher gave them a hint to solve the problem.

Explanation:

'A' is used before words that start with consonant sounds (“a sample” or “a model”), even if the consonant sound is made by a vowel (“a unit”). Conversely, 'an' is used before words that start with vowel sounds (“an equation” or “an element”), even if the word starts with a silent consonant (“an hour”).
