I got 14 out of 15 right on the logic test too, but I disagree with the answer on the one I got wrong. This is the question:
--------
Question 15.
a) Water is a molecule composed of two hydrogen atoms and one oxygen atom.
b) Every observation or examination by microscope has confirmed this.
Conclusion
Therefore we can predict that every future examination of water will reveal the same chemical composition.
-----
I say that this conclusion is valid since by item (a), Water is composed of two hydrogen atoms and an oxygen atom. So therefore every time we examine it, this is what it will be. If it isn't, then either we weren't examining water, or item (a) is false. However, the site says the answer is invalid. Bleh.
