Despite the lingering popularity of alternative health treat

Despite the lingering popularity of alternative health treatments for musculoskeletal injuries, such as acupuncture and chiropractic manipulation, it is quiet clear that the curative prowess of such so called remedies is questionable. In a recent survey of people who had tried at least one respondents reported that the thrapiest had little, if any, curative impact. People, with such injuries are, thus, well advised to forego alternative therapies in favor of traditional, interventive methods of treatment.

The above argument assumes that:

A. Other alternative therapies, such as aromatherapy, are not more effective than acupuncture or chiropractic medicine.
B. Traditional methods of treatment have a higher success rate than that of alternative therapies.
C. The survey participants had no reservations about the therapy methods they chose prior to receiving treatment.
D. No respondent had used any form of traditional treatment prior to the survey.
E. A combination of traditinoal and alternative therapies is the most optimal way to treat musculoskeletal aliments.
