Answer:
The rhetorical feature that Lincoln uses in this excerpt is:
d. allusion
Step-by-step explanation:
Allusion is a figure of speech that can be used as a rhetorical feature to help the speaker make his point. It can be defined as a reference to something or someone that has a type of significance concerning the topic that is being addressed. When an author or a speaker alludes to a place, an event, or a person, he does not offer much explanation about them, since it is assumed that they are important or famous enough to be known by the audience. In the excerpt we are studying here, Lincoln is alluding to God and the Bible in a way that helps him present his beliefs and arguments to the audience.
