How do we use "In case" in a complex sentence

Shall I keep some chicken salad for your brother in case he's hungry when he gets here?

Explanation:

In case means because something might happen/occur. It is often used before before a pronoun (In case you feel cold, take my coat) or at the end of a sentence (We don't want to be late so let's wake up early just in case).

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.)

the simple predicate of the sentence is camped.
