Answer:
Sarah needs to gather people of different races.
Step-by-step explanation:
A Coalition is an alliance between individuals that aims to achieve a common end. On the other hand, the word "multiracial" refers to people who are not descendants of a single origin.
On the basis of this reasoning, we can conclude that for Sarah to be able to build a multiracial coalition, she will need to bring together people from different backgrounds who want the police to stop judging people based on their skin color.
