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. which of the following is a correct decision and justification mario should make regarding the use of this source? mario should use the source. the author is unimportant. mario should use the source. the peer review is unimportant. mario should not use the source. the author is known. mario should not use the source. it has not been peer reviewed.

The correct answer is D. Mario should not use the source. It has not been peer-reviewed.

Explanation:

Before including any source in a research paper of any topic it is necessary to evaluate whether the source is reliable and credible, this depends on whether the author is known and an expert in the field; whether the information is updated and whether the information has been peer-reviewed, which means it has been checked and approved by other experts.

In the case of Mario, the source he found has a known author and seems to be updated as it was written recently; however, this has not been peer-reviewed and this implies the information has not been approved by other experts. This makes the source less reliable and credible and thus Mario should not use the source because it has not been peer-reviewed.

the correct answer is a.a peer
