Question

form a compound sentence.
my teammate stumbled
the race.
over the hurdle, but our team still won
over the hurdle but still finished
over the last hurdle, the highest in

Explanation:

To form a compound sentence, we need two independent clauses joined by a conjunction. The first option "over the hurdle, but our team still won" has two independent clauses ("My teammate stumbled over the hurdle" and "our team still won") connected by "but", making a valid compound sentence. The second option lacks a complete second clause, and the third is a fragment.

Answer:

A. over the hurdle, but our team still won
