Obviously the following statement is 'False':
"This sentence contains Seven words".
So we correct the sentence by changing it to:
This sentence does not contain Seven words".
We know that the First statement is False and so now can we conclude that the Second statement is True ?

re(4): Suggestions by Jayaram S)
Yes Jayaram, "This" in the second statement refers to the second statement only and not to the first statement. In fact, the word "This" in each of the statements refers to that particular statement only and not to the previous or the next statement.
