Question

Mario was conducting research regarding the treatment of AIDS victims using stem cells. He found a source that was written recently and the author was known. Unfortunately, he could not determine if it had been peer reviewed.

Answer 1

Mario should not use the source. It has not been peer reviewed.

Step-by-step explanation:

For Mario to have found the source and it shows that it was written recently, this should provide Mario with an idea that the source has not been peer-reviewed. The process of peer-review takes a lot of time usually between 17 weeks and 25 weeks. This is like 4 to 6 months. Hence it is not advisable for Mario to use the source, since it has not been peer reviewed.
