In Sherman Alexie's “Sacred Heart", he talks about his mother's illness and the family's concerns about how to best care for her. Is this any different from the concerns adult children
from other ethnic groups face as their parents age and require different types of care? If so,
how does it differ?

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.)
