Answer :

Parallel structure is referred to as a situation in English grammar where a grammatical form or structure is repeated within a sentence. Each grammatical form, being similar in structure, thus creates a parallel structure. Parallel structure helps in establishing balance and flow in a sentence. The correct answer with parallel structure is :

The concert begins at nine; it ends at midnight.

a. "to practice" is the best phrase to complete the sentence.

explanation:

during the summer, she likes to practice her soccer skills so that she is ready to play in the fall.

(note that : all the other options "the practicing of", "practice for" and "to do a practice on" are inappropriate as they make the sentence grammatically incorrect.)
