The choir gives(its,their) concert on third sunday in may.

Choir is singular. A singular pronoun must be used to refer to it.

In this sentence, the word "choir" is the subject, and it refers to a group of people working together. The question being asked is whether the correct pronoun to use with "choir" is "its" or "their."

To determine the correct pronoun, we need to consider whether the choir is being treated as a collective unit or as individuals.

If the choir is being treated as a collective unit, as in a single entity, then the pronoun "its" should be used. This suggests that the choir is seen as a singular entity with a singular possessive form.

If the choir is being treated as individuals, with each member being considered separately, then the pronoun "their" should be used. This suggests that the choir consists of multiple members who collectively perform.

Therefore, the correct pronoun in this sentence would be "its," indicating that the choir is being treated as a single group. The sentence would read: "The choir gives its concert on the third Sunday in May."
