Final answer:
Option B is the correct way to integrate a direct quotation, providing both accurate citation and the context necessary for understanding the quote's relevance. Therefore, the correct option is B.
Step-by-step explanation:
The student is asking which example correctly integrates a direct quotation from a passage discussing the importance of increasing vacation time for Americans to promote advocacy for national parks and wildlands. Considering proper citation practices, the correct integration of a direct quotation from the passage is option B which reads: John de Graaf explains, "The median American vacation of about a week - and even the average of two weeks - does not provide enough time for serious immersion in natural rhythms" (44). This quotation correctly includes the passage text inside quotation marks, provides appropriate attribution to the author, and supplies the page number where the quote can be found.
