Answer:
b. exhibited a critical attitude toward his sources but Herodotus did not
Explanation:
Herodotus based his explanations of human events on the will of the gods, besides having poor analytical rigor. His successor, Thucydides, excludes all religious aspects and seeks a purely rational explanation, with a rigorous examination of the sources. He had strict procedures for gathering evidence and its analysis in terms of cause and effect without reference to the intervention of gods.
