Answer:
a debatable generalization about the similarities and differences between literature from two different cultures.
Step-by-step explanation:
A claim can be defined as a statement that is used by a writer to prove, substantiate or support an argument. Thus, a claim is an assertive statement expressed by a writer to prove that an argument is true or real.
This ultimately implies that, when writers engage in an argument or write an argumentative essay, they make use of a claim to state or express their opinions about the subject matter or topic.
A comparative literature claim involves the use of available informations to illustrate the differences and similarities i.e comparing and contrasting two different things, so as to reach a logical conclusion.
Hence, the statement which provides the best definition of a comparative literature claim is a debatable generalization about the similarities and differences between literature from two different cultures.
