Answer: The correct answers are B
Step-by-step explanation:
The principle of justice means here a moral obligation to share gained knowledge for the benefit of others.
Eduardo should explain the results of his study in as many places as possible to make people aware of the benefits of eating broccoli to improve short-term memory. There is no point in keeping the results to himself, neither should he advertise the results in psychology circles as the study is not about psychology. If he is a student, he should start talking about his experience at schools where he might find people interested in his findings. If he works, his work colleagues should be his target. He could also consider writing about the results of this study in a local newspaper or even talk about it on a local radio station. Eduardo's goal should be to spread his knowledge to as many many people as possible so that they could benefit from his findings.
The best people to target would be people affected by memory loss themselves and looking for memory improvement tools, as they would really appreciate his findings. Eduardo could find a support group online and present his study there, he could also conduct some local research to see if any of his friends know somebody with this problem. Once he finds such people, he should get in contact with them and demonstrate to them the results of his study. This way, he contributes to spreading awareness about this issue and helps people affected by it directly.
