Final answer:
The phrase 'MAKE LOVE NOT WAR' was not written on Arnold Friend's car in the story.
Step-by-step explanation:
In the short story "Where Are You Going, Where Have You Been?" by Joyce Carol Oates, the phrase 'MAKE LOVE NOT WAR' was not written on Arnold Friend's car.
The story describes Arnold Friend's car as having the words 'ARNOLD FRIEND' and the numbers '33, 19, 17' written on it. These details are significant in revealing Arnold Friend's true identity and intentions.
The phrase 'MAKE LOVE NOT WAR' is a popular slogan from the 1960s counterculture movement, but it does not appear in the story or on Arnold Friend's car.
