Most murky sentences are murky for one reason: the main character is not in the subject slot and the main action is not in the verb. Work each sentence the way an editor does — click the word that hides the real actor, then the word that hides the real action — and the rebuilt sentence appears. Wrong clicks are worth making: every chip explains what it actually is.

The diagnosis, in two questions. Who or what is the main character here? What is that character doing? If the answers are not in the first eight words, you have found the problem — and noticing is most of the work.
Step 1 — find the character
Click the chip that names the person or group who actually does something.

Pick a case, then start clicking. Each chip tells you what job it is doing in the sentence, so a wrong guess still teaches you the anatomy.
