Final answer:
Add the transition 'as a result' to the beginning of the final sentence to sum up the argument in the paragraph and underscore the link between volunteering and its positive impact on resumes.
Step-by-step explanation:
The best way to revise the final sentence of the paragraph discussing the benefits of volunteering would be to add a transition that sums up the argument, indicating the conclusion of thoughts and providing a strong recommendation for action. In this case, the most appropriate transition would be "as a result." By starting the final sentence with this phrase, it highlights the causative effect of the information presented earlier in the paragraph on the action being recommended. Thus, the revised sentence could read: "As a result, students looking to improve their resumes should consider volunteering." This underscores the link between volunteering and its positive impact on employability and professional development, as discussed in the study mentioned earlier in the paragraph
