Marco, a real estate agent, receives a dozen emails in his inbox. Six of the emails are inquiries to a new condo listing he has in the North End. He confirms appointments with three of the prospective buyers, one of them decides that the condo won't work after receiving information on the layout of the property and the other email Marco ignores because the email address has a last name in it that appears to be Irish. Has Marco risked his real estate license

Yes because Marco discriminated by ignoring the email due to its appearance of being linked to someone of a different national origin

Explanation:

Real estate agents are not allowed to discriminate against buyers of property. Of they do they can lose their Liscence.

Discrimination is the act of behaving differently

and withholding benefits from people based on their race, colour, religion, sex, or gender.

In this scenario Marco ignores communicating with one of his clients because the email address has a last name in it that appears to be Irish.

He did not consider the application at all resulting in the client losing the opportunity to obtain the new condo.

As a result of this discriminatory action Marco stands the risk of losing his liscence
