<p>On the SAT chem test, for the TF part, can you ever a T F CE answer?
So in other words, if CE is true, then the two statements are both T T?</p>
<p>You can only fill in CE if both statements are true.</p>
<p>So the choices are:</p>
<p>A) F F
B) T F
C) F T
D) T T
E) T T CE</p>
<p>Exactly.</p>
<p>To know if it's CE or not though, you need to know whether the two statements are true, and whether or not they have a cause-effect relationship (ie first statement explains the other). Which is why it's only possible to have a CE if both are true.</p>
