Among people who have a history of chronic trouble falling asleep, some rely only on sleeping pills to help them fall asleep, and others practice behavior modification techniques and do not take sleeping pills.

Evidence

Among people who have a history of chronic trouble falling asleep, some rely only on sleeping pills to help them fall asleep, and others practice behavior modification techniques and do not take sleeping pills.

Those who rely only on behavior modification fall asleep more quickly than do those who rely only on sleeping pills.

Conclusion

So behavior modification is more effective than are sleeping pills in helping people to fall asleep.

Evaluate

First, there could be different degrees to which people have a difficult time falling asleep and those who have milder forms of difficulty may not seek pills to help them fall asleep; they may be comfortable with less aggressive measures. Second, there could be other factors influencing how difficult it is to fall asleep and perhaps those other factors do not permit the effectiveness of pills and behavior modification techniques to be compared.

    Why this is right

    This undermines the argument by suggesting those who tried modifying their behavior generally had less difficulty falling asleep. This makes it possible for sleeping pills to be more effective at helping people fall asleep, but that the people who take such pills already begin with a much more difficult time falling asleep.
