Let me spell it out more explicitly then.

Given that the following natural language statement is true:

--------------------------------------
Earth is the third planet from the sun.
--------------------------------------

In the following natural language statement:

--------------------------------------
At least one of the following statements is true:
- Earth is the third planet from the sun.
- <X>
--------------------------------------

Where <X> is any natural language statement, does there exist a 
statement X such that the condition "At least one of the following 
statements is true" is false?
