Question

what evidence shows that the uprisings at treblinka and sobibor were not a complete failure?
○ both camps were closed after the uprising.
○ prisoners attacked and killed ss men and guards.
○ thousands of prisoners escaped and were never captured.
○ all gas chambers in camps were shut down.

Explanation:

The uprisings at Treblinka and Sobibor had tangible outcomes that demonstrated they were not total failures. While the number of long-term escaped prisoners was smaller than "thousands", and gas chambers were not universally shut down, the fact that both extermination camps were closed shortly after the uprisings marked a major disruption of the Nazi genocide operation at those sites, making this the strongest evidence of the uprisings' partial success.

Answer:

Both camps were closed after the uprising.
