This is a book chapter, from a book titled Racial Healing: Confronting the Fear Between Blacks and Whites. What do you see as Dalton's purpose in the whole book? What might he
be trying to accomplish?

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.)

if the italicized words are he ran switfly, we can rewrite the sentence using a verbal phrase as follows:

running swiftly he was able to overtake the child.
