Hi Ron
I am really confused about the so-called intended meaning of the original sentence (Choice A). I've got dividing opinions from different sources.
Some teachers said that if the meaning of Choice A is reasonable, then any variation in meaning in other choices is wrong. This method, if true, will accelerate the speed for sure. But I tend to believe that there is nothing special about Choice A, but I am not quite sure about this. May I seek your confirmation?
Thank you!
