Before taking her calculus final, Heather reads a story about how men and women have equal abilities in math. As a result, Heather is likely to do well on her exam because of .
a. more; positive roles models.
b. more; reduce serotype threat.
c. less; positive role models.
d. less; reduce serotype threat.

b. more; reduced stereotype threat

Explanation:

Stereotype is defined as the false belief or idea of a thing by a person or group of people based on misguided information or "on the surface" judgement. From the above Heather defeats the stereotype that men have better abilities in maths than women by equipping herself with that knowledge before her exam, and us therefore likely to perform well in her exam with no stereotype threats.
