Step-by-step explanation:
The point of an argument is the main idea or thesis that the argument seeks to convey, whereas the support refers to the evidence and reasoning used to back up the point. In this case, the statement "Autos were seen as giving young people too much freedom and privacy, serving as ‘portable bedrooms’ that couples could take anywhere" is likely the point of the argument. This statement presents a clear, definite viewpoint about the social implications of automobile use. It is then supported by statements like debates between parents and teenagers over who could drive the car, the perceived impact of automobile use on church attendance, and the initial alarm caused by the introduction of automobiles to communities, all of which serve as evidence demonstrating the point.
