What kind of essay is it?
This sentence has unequal ideas joined by a subordination conjunction.
Since the ideas in the sentence imply causation (the broken pulleys caused the inability to raise the flag) it means that the ideas are unequal. It is also necessary to join them with a subordinating conjunction, which show the causality within the sentence. In this case that subordination conjunction is "because".
How about:
*Civil Rights Movement Kickoff
*Freedom Movement Kickoff
*Resistance to Racial Segregation Rise
*Rise of Resistance to Racial Segregation
*Root of Racial Segregation Resistance
Hope this helps! :)
