Can I re-state them, if you don't mind ?

u surely can.

Hey guys.. I found something will help you in the meaning issue.\
its from SC MGMT book.

Meaning: In the GMAT either the original sentence or its variations may muddy the waters......etc \

Sometimes the original sentence will have a clear, unambiguous meaning. In these cases, your goal is to preserve this original meaning as you correct other issues. Do not alter the author's intent when you make your choice.

At other times, the original sentence will be confusing, and you will need to discern the author's intent. Fortunately, this intent will not be too buried too deeply. After all, the correct sentence has to be one of the five choices. Thus, the GMAT tends to make use of small errors in meaning that can be easy to overlook.

Most instances of meaning errors fall into one of three major categories:
1- Choose your words.
2- Place your words.
3- match your words.

Thats enough.. if you want to go in details buy SC MGMAT book .

Thanks,
