Answer 1

You are prone to illness.

Explanation:

• Prepositions and post positions, combined known as ad-positions, are a group of words used to depict spatial or temporal relations or mark different semantic roles.

• Prepositions show relationships between other words in a statement.

• Many prepositions have many definitions, so the meaning alters quite a bit in various contexts.

• Finishing a statement with a preposition is not taken as a grammatical error.
