Question

which of these helps the reader determine the credibility of the selection? a the source discusses biology, something based in science. b the passage contains challenging and technical vocabulary. c neuroscience is one of the most challenging fields of study. d the author has studied the science being described in the text.

Explanation:

To determine the credibility of a selection, knowing the author has studied the science (option D) gives insight into their expertise, which supports credibility. Option A just states the topic, B is about vocabulary difficulty (not credibility), C is about the field’s challenge (not about the selection’s credibility).

Answer:

D. The author has studied the science being described in the text.
