Final answer:
Steering is when a broker automatically takes a Greek person to see homes in a Greek neighborhood without asking where they want to live. This practice can perpetuate segregation and limit housing choices.
Step-by-step explanation:
The action described in the question is known as steering. Steering occurs when a broker or realtor directs a prospective buyer towards homes in a particular neighborhood based on the buyer's ethnicity, without considering the buyer's preferences.
While steering can be seen as an attempt to help buyers find homes where they feel comfortable, it can also perpetuate ethnic segregation and limit housing choices.
It's worth noting that steering may not always be intentional or discriminatory, as some realtors may believe they are assisting buyers in finding a community where they will feel at home.
