Despite the lingering popularity of alternative health treat

Pre - thinking : Author says " for such injuries, let go of alternative therapies and use traditional methods to cure " . This means the author believes that traditional
methods are better. Lets look at options and see if we have anything on these lines :

A. Other alternative therapies, such as aromatherapy, are not more effective than acupuncture or chiropractic medicine. Out of scope

B. Traditional methods of treatment have a higher success rate than that of alternative therapies. Sounds fine Hold it

C. The survey participants had no reservations about the therapy methods they chose prior to receiving treatment. Whether they had reservations or not, it does not fill the missing link. If at all we choose this, we are bringing our general knowledge to solve the question and that is an absolute no - no

D. No respondent had used any form of traditional treatment prior to the survey. sounds fine to me

E. A combination of traditional and alternative therapies is the most optimal way to treat musculoskeletal aliments. does not lead to the stated conclusion

Down to Option B & D :
B is clearly more aligned with our pre thinking than D.


Let me try to explain more on why D is wrong :

If we negate Option D , : "Respondents had used traditional treatment prior to the survey".

Now this doesn't indicate if the treatment was effective, if the treatment cured them.

The results can be both - the traditional treatment was not effective, therefore they turned to alternative therapy ;
the alternative therapy was not effective, therefore they turned to traditional treatment.

In all probability (sends me into tizzy, in quant ), the option D does not void the argument when negated.

Hope it helps.
