Jesting with them and turning their hunger for food into homesickness
Answer: Option one
Explanation: Most logical answer.
The first answer is correct (A).
A strong research requires, first and foremost, a questioning, a question that seeks an answer. The act of searching is driven by the search for answers. Necessarily, the scientific methodology suggests that the researcher has a hypothesis for that question.
This hypothesis is the guiding principle of the research, and is based on evidence and the researcher's experience and knowledge. However, finding the search answer may or may not confirm the hypothesis.
I would say that for example an unethical tactic would be to promote the expanded use of hydrocarbons by expanding pipelines and tanker traffic which can result in oil spills on land and also in the precious oceans. Another unethical thing from the past was to promote the smoking of cigarettes by making it look 'cool' thus ignoring the potential damage to one's health from lung cancer.
