Question

scientists often begin their research by reading articles published by others on the same or a similar topic. this is because the articles

○ provide information that we can use in our own project.

○ give us a research project to retry.

○ show us what has been done and what to avoid researching.

○ tell us the proven facts about our subject.

Explanation:

• Option 1: While articles can have usable info, the main reason for reading prior research is to know the research landscape, not just for using info in one's project.
• Option 2: Articles don't typically give a project to retry; they present existing work.
• Option 3: Reading prior articles helps identify the research that has already been conducted (so we don't duplicate) and what pitfalls or unproductive areas to avoid, which is a key reason for literature review in research.
• Option 4: Articles may present theories, findings (not all proven facts), and ongoing research, so this is not the main reason for reading them at the start of research.

Answer:

C. show us what has been done and what to avoid researching.
