Answer: d. identify relevant sources of information.
The first thing to do before you start looking at resources would be to identify which sources of information are the most relevant ones. There are several factors to take into account. The sources have to be reliable, and the studies they describe need to have been conducted in a scientific, systematic way. The sources also need to discuss the issues that you want to address. Finally, the sources should be available to you, whether this is through school, through a library or on the internet.
