Answer:
The best description for your sharing with Nathan is: hearsay.
Explanation:
A primary source can be defined as any record, document or object containing first-hand information. In other words, a primary source is produced by someone who participated in the event the source is related to.
A secondary source is a record, document or object produced by someone who did not participate in the event. It is often produced some time afterwards, and it relies on primary sources to be created.
Plagiarism means using someone else's words, ideas, research etc. as if they were your own, without mention the original author.
Finally, hearsay or hearsay testimony is a repeated account. That is, you hear someone say something and then repeat to someone else. You, the one who is repeating it, did not participate in the event. That is precisely the case described. You are not the one who did the test. It was Hiram. All you did was repeat his account to Nathan. This characterizes hearsay.
