Answer to Question 1

ANS: B
Literature reviews provide a picture or describe what is known and not known, or also stated as gaps in the knowledge of the subject or phenomenon under study.
Studies considered classic in a field are often included, even if they are more than 5 years old.
Literature reviews present only relevant studies from credible sources.
The research question drives the researcher in developing the study, including determining the type of analysis that will be used.

Answer to Question 2

ANS: C
A rigorously conducted quantitative study has precise measuring tools, a representative sample, and a tightly controlled study design.
Creating a tightly controlled design will help show causality between dependent and independent variables.
If it is a researcher-developed instrument, the validity and reliability are in question.
It does not say how the sample was selected, so it is not known if it is representative.
