Question

Why can’t you just use all of the details in your research report as details for your oral report?

Some of the details are more convincing in writing than in a speech.
It’s not fair to use information that you already researched for a different assignment.
You may not have time to include them all and go into enough detail about each one.

Answer 1

You may not have time to include them all and go into enough detail about each one.

Step-by-step explanation:

Before presenting an oral report, a research report which is an extensive inquiry into a subject matter is first made. A research requires consultations from different authorities on a subject to obtain their opinions. Sometimes, the research report in a text form might be voluminous because of all the resources gathered.

It might then not be possible to transmit all of the information orally because of time constraints. Therefore, only the main points should be conveyed during an oral report presentation.
