In the sentence pattern for asking questions, the subject is placed immediately after the operator (Operator [did, does, was] + Subject) while in the sentence pattern for making statements, the subject is placed before the verb phrase (Subject + VP). However, some statements may be in question form (You've already eaten?) and some questions (such as rhetorical ones) may be in statement form (Haven't you peed already?).
I took a test on this and my answer was correct to show emphasis the helping verb would be DO SO (A) is the correct answer
Answer: I can’t think of a more important point in listening than to be quiet so you can hear what someone is saying. To question, in your own mind, “was that IS or IS NOT”? because of unnecessary interruptions by someone else talking or making too much noise can cause you to lose even more! While you are wondering, you cannot concentrate as well on what you hear if you are thinking about what you may already have missed! These things put you even further behind.
This may sound like a small point, but even someone smacking gum or some other unnecessary noises can interrupt the flow of the speaker, what they say, (or what you thought they said), and can cause you to not hear clearly, and miss an important point. It is far more effective for the listener, and the speaker, if quiet and absolute, focused attention is maintained. It is also simply good manners to not interrupt the others. If you do not want to learn, quietly leave.
