Reasonable conclusion expected:
A. Cameras with fixed length lenses are too bulky for anyone but the professional photographer
"anyone but professional photographer"...too harshB. Serious photographers are concerned primarily with superior image quality.
"primarily with superior image quality" again, too harsh. passage says "interested", not "primarily concerned". something else could be the primary concern for serious photographers.C. Despite claims to the contrary, traditional film cameras are still the best choice for professionals
nowhere does the passage talks about traditional camerasD. Cameras with folded optics system generally do not produce image quality as those with interchangeable lenses.
this is the correct answer. the author talks about how 2 different kinds of people should go about choosing their camera with regards to the importance they might place on "picture quality". the ones who do not care for great picture quality and do not want to tote heavy equipment around should go for folded optic system ----reasonable inference -->> the interchangeable lens adds weight. E. Price should not be a primary factor in determining whether to buy a particular camera.
price is out of scope
