TOEFL - Section 2 - Giúp sửa lỗi.

Thanks Thuyenxaxu,
Now I misquoted myself didn''t I. Still don''t know how the word "tooth" got squeezed in there.
?oDrinking water containing excessive amount of fluorides causes the enamel of teeth to become brittle and to chip off, leaving a stained or mottled effect".

No problemo ... Everyone, including me, creates typos from time to time, bro !

Thank a million both two of you.
I just duplicated that question from the Toefl test material( got somewhere in the internet). I also thought that question have some problems. But I didn''t know exactly what they were, so I asked you, friends.
Now, everything is clear.
Again, thank for your help
