Which of the following answers is a proposal attachment?

The correct answer is the documentation to support the proposal narrative because it provides substantiating evidence that underpins the claims and objectives outlined in the proposal. This type of attachment is crucial for demonstrating the feasibility, credibility, and potential impact of the project. It can include data, letters of support, or any relevant research, which helps reviewers to better assess the project's validity and alignment with their funding goals.

Attachments like a cover letter, a summary of project goals, or an introduction to team members may support the proposal but do not serve the central purpose of bolstering the narrative with concrete evidence. While these elements can enhance the overall presentation of a proposal, the core expectation is to provide clear and detailed documentation that directly supports the proposal’s main arguments and methods. Such supporting documents can significantly strengthen a proposal by reinforcing its claims with measurable evidence, making it more compelling to the review committee.
