問4.5が分かりません。出来るだけ早めに解説と答えお願いします🙏🙏

SCientists must accept their experimental findings even when they would like them to be different. (4) They must strive to distinguish between the results they see and those 15 they wish to see. This is not easy. Scientists. like most people, are capable of fooling themselves. People have always tended to adopt general rules, beliefs, creeds, ideas, and hypotheses without thoroughly questioning their validity. And sometimes we retain 20 these ideas long after they have been shown to be meaningless, false, or at least questionable. The most widespread assumptions are often (g the least questioned. Too often, when an idea is adopted, great attention is given to the instances that support it. Contrary evidence is often distorted, belittled* or ignored. T1
