Here are the points take them please

Ok Thank you so much. Have a wonderful Happy Halloween

Thank you so much. Hope next Halloween is better! Including all other holidays too, like Christmas!

Explanation:

It says in the text that millions or people had come from different parts of the country to go into Washington, D.C. to protest. So congregate means to gather around in a mass.

So the context clues would be “meet on the National Mall” “millions of people” “their voices heard”.

hope this helps
