What is the function of complement shown in parentheses this sentenceTina sings choir and performs solos?

The word "and" in the sentence "Tina sings in choir and performs solos" is a coordinating conjunction. It connects two grammatically equal parts of the sentence, in this case, two verbs: "sings" and "performs".

Here's how it works:

* "Tina sings in choir" is a complete thought (an independent clause).

* "performs solos" is also a complete thought (another independent clause).

* The conjunction "and" joins these two independent clauses to form a single, longer sentence.

The "and" in this sentence serves to show that Tina does both activities: sings in choir *and* performs solos.
