<em>The correct options are</em>
<em> B) If the sources used are peer reviewed</em>
<em>D) If the writing is based on sound evidence</em>
Explanation:
To check whether a scientific report is valid or not, one must determine whether the results deduced from its experiments were accurate and true or not. If the writing provides sound evidence for its experiments to be true and not biased, then the editor will most likely publish it. A report that is supported by peer reviews will be the best to publish as the data in it will be considered to be more authentic and accurate. Hence, option B and D will be true.
