The reader can make of it what they want. This may seem like a perfectly reasonable sentence in English to most people, but it has a serious problem. If the word “readers” is plural the problem goes away, but it’s singular for a reason. The subject is the reader, who is referred to later as “they”. In this case, “they” is not a plural pronoun, but a singular one meaning “he or she”. It’s a common usage, but it’s wrong. So what is the problem?
