ESSAYBID ANSWER

ANS: A
The advantage of performing a complex search is that the results of the search are limited to sources that only include all of the topics needed, thus limiting the number of irrelevant references.
Although hundreds of sources may be found, this is not necessarily an advantage unless they are needed, and if the search is limited appropriately, then the number of sources may be much smaller.
Each database has its own rules for searching.
Although irrelevant sources are more limited, the researcher still must cull out those that are not appropriate.
