what makes the passage believable?
a. it uses formal and scientific - sounding language.
b. it has a lengthy title that sounds very official.
c. it includes short sentences that are easy to understand.
d. it contains information people would like to hear.

Explanation:

The passage employs terms like "amino acid thalythin," "oxygenate the blood," and references "proven" effects, which mimic scientific discourse. This formal, science-like language can create an illusion of credibility, making the passage seem believable despite flawed content (e.g., misclassifying cabbage/broccoli as junk food). Other options are incorrect: the title is short ("4.2.2 Quiz: Understand Assumptions of Truth"), sentences are not uniformly short, and desirability of information (D) does not directly make it believable.

Answer:

A. It uses formal and scientific-sounding language.
