After a team of scientists completes an investigation, they submit an article about the investigation to a scientific journal. Before the journal publishes the article, they send it to other scientists for an anonymous, independent review. What is the purpose of this review?

To make sure that the information in the article is true, and correct.

2. Data is supported by other background research,

3. Cited the research articles,

4. Experiment can be replicated by any other scientist to prove the hypothesis.
