Summary of the foolish donkey

C). Obama uses logical evidence, since it is reasonable to state that refugees want homes of their own.

E). Obama uses anecdotal evidence, since he shares a personal experience he has had with a refugee.

Explanation:

Evidence plays a vital role in establishing the credibility of a claim and convince the readers to believe and accept the claim.

As per the question, the 'use of logical and anecdotal' evidence would help president Obama to establish the validity of his claims and persuade the readers to accept them. The logical evidence would convince them logically to believe that 'refugees need and want to possess their own homes' while 'anecdotal evidence' would help in validating the claim and persuade the audience ethically(as the speaker is the president himself who shares his personal observation). Therefore, options C and E are the correct answers.
