I am a high school student studying English in Korea. I am asking this question because school changed the original text on the English test. So, I have some question and want to get your explanations. please check it up and answer. Have a happy day. thx
[Question] When reading another scientist’s findings, think critically about the experiment. Ask yourself: Were observations recorded during or after the experiment? Do the conclusions make sense? Can the results be repeated? Are the sources of information reliable? You should also ask if the scientist or group conducting the experiment was unbiased. Being unbiased means that you have no special interest in the outcome of the experiment. For example, if a drug company pays for an experiment to test how well one of its new products works, there is a special interest involved: The drug company profits from the experiment it shows that its product is effective. Therefore, the experimenters aren’t objective. They might ensure the conclusion is positive and benefits the drug company. When assessing results, think about any biases that may be present!
[Original text] : The drug company profits if the experiment shows that its product is effective.
