What does a job candidate’s reference do? (health science)
a-writes a formal letter about how he or she knows the candidate so the candidate will be able to take the letter to a job interview
b-responds to a call or an email from an employer seeking information about a possible job candidate
c-investigates a company for a job applicant
d-identifies job applicants for an employer and collects their résumés

it should be B, responds to a call or an email.

Explanation:

When i submit job applications, i put my references and to jobs references are people you use to work with, friends, or your boss. The company calls those people and asks about your working ethics, and your customer service. I hope this helps.

it's false.

"every person has their limitations which prevent us from accomplishing something. some are better than mathematics for example and some are worse. those people who are worse might never be able to become mathematicians, but that does not mean that they would not be great at doing something else."
