Final answer:
The idea that human behavior is motivated by a drive to physically survive is flawed because survival instincts are overridden by cultural influences and the concept of physical survival is irrelevant to human behavior. Humans are driven by the need for social acceptance.
Step-by-step explanation:
The reason that the idea that human behavior is motivated by a drive to physically survive is flawed is because the text argues that survival instincts are overridden by cultural influences. The text suggests that the concept of physical survival is irrelevant to human behavior. The text claims that humans are inherently driven by the need for social acceptance. Therefore, option 1 is the correct answer.
