Answer to Question 1

ANS: C
Blinding refers to a procedure where the researcher or evaluator does not know which partici-pants are in the experimental or control group. The other factors do not relate to the importance of blinding.

Answer to Question 2

ANS: A
Because it is difficult to find or perform randomized controlled trials in the community, other types of evidence have been highlighted as the best evidence in public health literature upon which to base EBPH practice; scientific literature found in systematic reviews is one type that is recommended. Although randomized controlled trials are the highest level of evidence with qua-si-experimental studies and expert opinion both being lower on the list of evidence. It would not be possible to implement randomized control trials or quasi-experimental studies when studying smoking cessation. Expert opinion would not be as helpful when looking at methods that have literature that support their use.
