20. A disadvantage of using a sentence outline instead of a topic outline is that a sentence outline is often


A. rigid.
B. factually grounded.
C. underdeveloped.
[D. time-consuming.]

Yep!

The correct answer is D. time-consuming.

To determine the correct answer, we need to understand the difference between a sentence outline and a topic outline.

A topic outline typically consists of short phrases or words that represent the main points and subpoints of a text. It provides a general overview of the content without going into much detail. On the other hand, a sentence outline consists of complete sentences that provide more specific information about the main points and subpoints.

Now, let's analyze the given options:

A. Rigid: Both sentence and topic outlines can be structured in a rigid manner, so this is not a clear disadvantage specific to sentence outlines.

B. Factually grounded: Both sentence and topic outlines can be factually grounded, so this is not a clear disadvantage specific to sentence outlines.

C. Underdeveloped: Sentence outlines are usually more developed than topic outlines, as they contain complete sentences that provide more detailed information. Therefore, this is not a disadvantage of using a sentence outline.

D. Time-consuming: The correct answer is D. Compared to a topic outline, a sentence outline requires more time and effort to create. Writing complete sentences for each point can be more time-consuming, especially when dealing with lengthy texts.

In summary, the disadvantage of using a sentence outline instead of a topic outline is that it can be time-consuming.
