Okay, Gerald Ford served 1 term from 1974 to 1977. John F. Kennedy served a partial term (because of his assassination) from 1961 to 1963. Richard Nixon served 1 full term as well as a partial second (because he resigned from office) from 1969 to 1974. Lyndon B Johnson served a partial term (because he was sworn in after Kennedy's assassination) and then a full term after that from 1963 to 1969.
So, you answer would be John F. Kennedy, Lyndon B. Johnson, Richard Nixon, then Gerald Ford.
Hope this helps!
Hi. You did not enter the text to which this question refers, which makes it impossible for your question to be answered. However, I will try to help you as best I can.
A textual evidence is a justification that the author uses to prove an argument presented in the text. This evidence seeks to present elements that prove that the author's argument about something must be considered correct and true. In this case, to answer your question, you should read the entire text and identify the sentences the author uses to prove that the late nineteenth and early twentieth centuries were crucial decades in the development of Western thought. In this case, the author can present the scientific discoveries made during this period that were essential to explain and solve several problems that humanity did not know how to solve.
I believe that it is B however, I'm not positive.
