Provide a perspective: the behavior of the old lady is rooted in ignorance, and this ignorance is not a case, but a common phenomenon among the elderly. Contact those elderly people who have been cheated by telecommunications, preferring to believe the liar rather than the police. Because of material reasons and the social environment at that time, these old people often have no good education, no news and little contact with new things outside. Moreover, elderly people will throw coins on the engine to pray for blessing, and they will be deceived by the liar's lies about eliminating disasters, because all they expect is a happy life and the safety of their children. It would be a negative intention to criticize the old lady's ignorance. We can discuss how to protect the minds of elders from "ignorance" and who should be responsible for ignorance.

PS: I hate argumentative essays in high school.
