Which sentence uses consistent verb tense?
1. the police officer rounded the corner and pumps his arms harder.
2. the animals scrambled to get into the barn as the lightning struck.
3. alexander finished his math test and walks to mr. smith's desk.
4. sampson and raina watch the fireworks and will comment on how beautiful they are.

The answer is 2. I answered before and I was correct but the admins keep deleting it. So, if you guys could stop deleting this so I don't have to keep rewriting it that would be nice.  .-.

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.)
