Question

why is
oman aqueducts\ a credible source of information?
a the author is an historian and architect himself.
b the passage includes a discussion of american history.
c the information comes from an authoritative source.
d the author quote senaca, a famous roman author.

Explanation:

A credible source relies on authoritative, relevant information. Option A is incorrect as there's no indication the author is a historian/architect. Option B is wrong because American history is unrelated to Roman aqueducts. Option D is incorrect as quoting Senaca alone doesn't make the whole source credible without confirming the passage's core source. Option C is correct because information from an authoritative source directly supports credibility for a topic on Roman aqueducts.

Answer:

C. The information comes from an authoritative source.
