What is the purpose of a monologue?
a. to confuse the audience
b. to explain the ending of a movie or drama
c. to show a character's thoughts and motivations
d. to make the script longer

Hint: A monologue is an individual character’s speech where they express their point of view and their perspective aloud. It is often done while directly addressing the audience or sometimes while addressing the other character.

Complete answer:
From the hint given to us, we know that a monologue is an individual character’s speech where they express their point of view and their perspective aloud. It is often done while directly addressing the audience or sometimes while addressing the other character. Thus, we can infer that a monologue helps us understand the character’s thoughts and motivations, with respect to the plot. We observe that option C, to show character’s thoughts and motivations, is similar to our inference from the description of a monologue. Hence, option C is the correct answer.
Let us understand why the other options are incorrect:

a. Monologue does not confuse the audience, it offers clarity instead. Hence, option A is not the correct answer.
b. Monologue’s purpose is not to explain the ending of a drama or a movie, but to explain the depth of a character. Hence, option B is not the correct answer.
c. As already discussed, option C is the correct answer.
d. Monologue’s purpose is not to make the script longer as we have already inferred. Hence, option d is not the correct answer.

Note: A monologue can also be used outside a drama or a movie, as a reaction to a particular issue.
