Passage Summary: Modern car washes use cloth strips called mitters instead of brushes because they are less likely to damage a car's paint. This is a big deal for newer cars, which have a clear-coat finish that is more delicate than the paint used on older cars.

Reasoning: Mitters are gentler on car finishes than brushes, which is particularly relevant for modern clear-coat finishes that scratch more easily than older ones.

Analysis: Since this is a 'Most Strongly Supported' question, we aren't looking for a flaw; we are looking for a logical extension of the facts. We know two things: mitters are safer than brushes, and clear-coat finishes are more vulnerable than old finishes. It follows that if you have a car with a clear-coat finish, using mitters is a significantly better choice for avoiding scratches than the old brush method. Look for an answer choice that connects the vulnerability of clear-coats to the protective benefit of mitters.
