The essential questions answered in the introduction of a recommendation report are similar to those answered in the introduction to what other kind of document?

A) a proposal
B) an incident report
C) meeting minutes
D) a job-application letter

The introduction of a recommendation report typically includes the background and purpose of the report, as well as an overview of the problem or issue being addressed. This is also typical of a proposal, which introduces the problem or need for a solution and includes a proposed solution or course of action. While meeting minutes and incident reports may also have introductions, they are typically more focused on summarizing what occurred rather than introducing a problem and proposed solution. A job-application letter is not typically used to introduce a problem or propose a solution.
