What type of information establishes a fact or raises belief in something?

The correct choice is evidence because it refers to information or data that is presented to support or establish the veracity of a claim or belief. In professional communications, evidence can take many forms, including statistics, research findings, case studies, or firsthand accounts that substantiate an argument. By providing reliable evidence, a communicator enhances the credibility of their message and helps the audience form a reasonable belief based on the information presented.

Testimonial focuses more on personal accounts or endorsements, which can be persuasive but do not necessarily constitute objective proof of a fact. Justification refers to the reasoning or rationale behind an argument, which may involve evidence but is not in itself the actual supporting information. Assertion is simply a statement claiming something to be true, but without evidence, it lacks the foundation needed to convincingly establish a fact or belief. Therefore, evidence is critical in effectively substantiating claims in professional communication.
