A study of high blood pressure treatments found that certain meditation techniques and the most commonly prescribed drugs are equally effective if the selected treatment is followed as directed over the long term. Half the patients given drugs soon stop taking them regularly, whereas eighty percent of the study's participants who were taught meditation techniques were still regularly using them five years later. Therefore, the meditation treatment is the one likely to produce the best results.

Which of the following, if true, most seriously weakens the argument?

People who have high blood pressure are usually advised by their physicians to make changes in diet that have been found in many cases to reduce the severity of the condition.

The participants in the study were selected in part on the basis of their willingness to use meditation techniques.

Meditation techniques can reduce the blood pressure of people who do not suffer from high blood pressure.

Some of the participants in the study whose high blood pressure was controlled through meditation techniques were physicians.

Many people with dangerously high blood pressure are unaware of their condition.
