Answer:
3. "We know what it's like to be told there's not a screen for you to be featured on, a stage for you to be featured on."
4. It's mind-boggling what Boseman was able to accomplish, facing down an industry's historical prejudice while suffering through cancer treatments
Step-by-step explanation:
The two statements above reveal that Chadwick Boseman really put in a lot of effort to sell his craft despite the challenges he encountered.
3. "We know what it's like to be told there's not a screen for you to be featured on, a stage for you to be featured on.": This statement is an example of a specific challenge Boseman experienced. He was racially prejudiced, and as such was denied a chance to display his art on stage. The stage would have provided the medium to let black voices be heard.
4. "It's mind-boggling what Boseman was able to accomplish, facing down an industry's historical prejudice while suffering through cancer treatments": This statement shows that he had to put in extra efforts to elevate black voices even though he was undergoing cancer treatments.
