Answer:
A.) A series of traps
C.) Sociological Imagination
C.) Both society affects individuals' lives and individuals in turn make an impact on society.
A.) Public Issues
Step-by-step explanation:
For the first question, Millis states (in the very first paragraph) that many young men feel that their private lives are a series of traps. They can sense that in their day-to-day world they can't overcome their troubles. I.E. unable to change anything about their lives due to a lack of choices and power.
For the second question, "What concept does Mills say is a way of seeing the intersection of history and biography?" Millis coins the term "Sociological Imagination" as a way to explain how you can use logical reasoning in a larger context of both history and culture to explain many social events and personal experiences (whether they be problematic or not) in the context of society as a whole.
For the third question, "Which of the following best represents Mills' view?" is in reference to his overall view of society and how he thinks it impacts people living in it. He says that while the individual may be affected by society (as to be presumed) they can impact the greater society through greater means even if unintentional. Both influence each other in many ways.
Finally, "According to Mills, using a sociological imagination allows us to view people's private troubles as:", can be answered with "Public Issues" as sociological imagination is the term we use to explain using logic and reasoning to explain many phenomena in the terms of how they are impacted (and impact) the greater society we live in.
(Additionally, "issues" and "troubles" doesn't have to mean something negative, it's just an event that impacts each individual)
