Question

what is john lewiss most likely purpose when he talks about his experiences with the public library?

to turn the discussion to the subject of his writing

to show how much has changed in a few decades

to explain why passing the literacy test was difficult

to demonstrate that he was determined to create change

Explanation:

John Lewis's experiences with the public library (likely in a context related to civil rights, literacy, and his activism) would most likely aim to show his determination to create change. His work was centered around social change, and sharing such experiences would highlight his resolve. The other options: turning to writing subject is less likely, showing change over decades is not the core purpose here, and explaining literacy test difficulty is not the main intent of library experiences.

Answer:

To demonstrate that he was determined to create change
