VERY EASY! My claim is this: Tablets should be used instead of textbooks because they have an unlimited amount of knowledge, allows personalized training,
I need one more reason on why tablets should be used that's it :)

is it rising action, falling action, climax, or resolution? need answer also

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.)
