Which excerpt from "Finding Unity in the Alabama Coal Mines” best supports the theme "When people work together through difficult times, they can impact future generations”?

Although racial separation was embraced by many, there were some individuals and organizations that worked toward unity of the races.
When the miners still continued to strike, Alabama Governor Braxton Bragg Comer sent in state militia members to break up the tent city, resulting in the end of the work stoppage.
Members of the UMWA, however, resisted the tradition of racial separation, believing that such divisions defeated their common goals.
Although the strike was defeated, the unity of the UMWA workers laid the groundwork for successful interracial organizing in the decades to come.

The passage that best supports this theme is the one that shows that although the strike was defeated, the UMWA workers' unit laid the foundations for a successful interracial organization in the following decades, as shown in option four.

We can come up with this answer because:

The text shows how workers came together to claim rights that were being denied.
These workers were very different from each other, even racially, but they put aside their differences to ensure that their rights were met.

The strike that the workers established did not have the results they had hoped for, but it showed that interpersonal organizations were powerful and could be very beneficial, especially in the future.
