Traveling medicine shows were a major form of entertainment in nineteenth-century, small-town America. To hard-working people who saw too little of the broader world, the shows’ comedy and musical skits provided a welcome diversion from daily routines. Once a crowd had assembled, a distinguished-looking gentleman who invariably bore the title of “doctor” began his sales pitch for some concoction or another made from “nature’s elixirs” that promised to cure everything from warts to the common cold. Despite the obvious exaggeration of such claims, business was often good. Though traveling medicine shows are now a thing of the past, medical trickery is not. Like their nineteenth-century counterparts, modern-day quacks seek to take advantage of common fears of pain and death through the promotion of a “miracle treatment.” It is, therefore, essential that consumers be able to assess reports about various drugs and medical procedures. ____________________________________ ________________________ Common sense also helps. Remember: if a report sounds too good to be true, it is usually just that.   Which of the following is the best meaning of the word quacks as it is used in the second paragraph of the passage?     

My family traveled everywhere in that battered 1959 Volkswagen van, ballasted by several gray boulders of unknown origin. That rocks would be used to steady the vehicle did not seem strange, since my father was a geologist. What was surprising was that his geologic zeal did not land us in the hospital. Whenever my father spotted an interesting rock formation, he forgot about everything else. The van would hesitate, as if caught in a stiff crosswind, then slowly drift toward the shoulder. “Early Devonian shale sediments,” he might mutter, as the van slowly wandered from the road to the shoulder and back to the road again. Turning to the four of us—the van now headed for the center lane—he would wave his hands for emphasis. We learned early not to ask for explanations.   Which of the following statements best expresses the main idea of the passage?
