Answer:
B He ended the section with the words, "But then--"
Step-by-step explanation:
The writer of "The crossover" builds suspense by heightening tension about not knowing what next would happen by ending the section with an incomplete sentence "But then--".
Kwame Alexander keeps the readers hooked when he ends the section of Josh playing with his father by not completing a sentence, therefore making the readers not know what next to expect.
