Which of the following is a benefit of literature reviews in research?

The correct choice highlights that literature reviews typically require less time to conduct than primary research. This is because literature reviews involve analyzing existing research and synthesizing findings rather than going through the primary research process, which can be time-consuming. Conducting primary research often involves designing studies, gathering data, and analyzing results, all of which take significant time and effort. In contrast, a literature review allows researchers to build on existing knowledge more efficiently, pulling together insights from multiple studies, and can be completed relatively quickly.

As for the other options, literature reviews do not eliminate the need for additional research; they may highlight gaps that still require investigation. While they can provide access to modern studies, it isn't guaranteed that all literature reviews focus on the latest research. Furthermore, literature reviews do not always yield high-level quantitative data, as they can comprise qualitative studies or varied methodologies.
