The most effective way for Olivia to make the sentence more readable is: b. Change the first "and" to "or."
To enhance readability, Olivia can opt for option b, changing the first "and" to "or." This modification provides better flow by avoiding repetitive use of "and" and introduces a logical contrast in the sentence.

This not only improves the sentence structure but also maintains clarity, allowing for a smoother and more engaging presentation of the events during the Cuban Missile Crisis. Hence, option B is correct.
