Messr. Stolyar:
Methinks you are being a little harsh here. For one thing, while I am a newbie to this particular forum, I have been a teacher and tutor for many years, and, having participated on many other similar forums, I believe there are no "stupid" questions.
You are obviously one of the more intelligent people on this forum -- please do not succumb to the temptation to become a "snob" -- holding the opinion that only questions that are challenging to YOU are worthy of posting to this board.
There are many foreign speaking participants for which the nuances for the English language are quite daunting (in fact this is true for many native-born Americans as well) and the intent or explanation of the sometimes "technical" language of ETS is often hard to understand at times, even to me.
Just my opinion....
