Jim chose bill and terry fir his team; sandra chose gina and mary; luke chose audrey

The sentence is grammatically correct.

There is one typo on the word "for."

Explanation:

Semicolons are used to connect independent clauses in a sentence, without giving more weight or importance to any of them.

Independent clauses are groups of words that contain both a subject and a predicate. They can function as complete sentences or combined to create a compound sentence.

In the example given, there are three independent clauses:

The clauses are linked with a semicolon in order to avoid the repetition of "for his/her team" and the use of a conjunction (and, but, so).

This is cheating no matter what your cause is.
