Final answer:
The correct choice is B) shows, which maintains consistent present tense in sentence 13, reflecting the ongoing action of Lee honoring and valuing his cultural tradition.
Step-by-step explanation:
The best version of the underlined word in sentence 13 is B) shows. To maintain consistent verb tense throughout the sentence, the present tense verb 'shows' should be used. The sentence refers to Lee's ongoing action of honoring his family's homeland and the value placed on the tradition, which is a continuing state. The sentence reads: 'By writing this poem, Lee honors his family's homeland and shows the value he places upon the tradition of expressing memories through song.'
