In which case mucose membrane via the facial mucosa like the olfactory nerves and mucosa, or the sublingual or oral mucose. The olfactory route is usually the fastest as some substances can travel the short distance via the nerve or the through the vasculature or the membrane. Cocaine is the biggest example.

Answer:

I would say that the best answer to the question: What is the dependent variable of this research, would be: A) Information alone is not sufficient if people are not motivated to use it.

Explanation:

A dependent variable is the one in research whose result will entirely depend on the outcomes of the independent variables. In this case researchers decided to use different means of information on smoking to achieve the reduction of their smoking. While to a group they showed them a video and gave them a pamphelt with instructional information on how to quit, to the other group they subdivided it and gave one portion just the video, and the other just the pamphlet. In the end, the result was that during follow-up, researchers found that the group with the least reduction in smoking was the one to whom only the pamphlet had been given. This result showed that the pamphlet, which was the information only, was not enough to encourage smokers to leave the habit. It became evident that a factor of fear was necessary to achieve that final goal.
