We actually had a pretty good discussion on why this was incorrect.
1. The causal relationship: This is an "if then" statement. The thing we are trying to prove true (the conclusion) should be in the "then" part of the "if/then"
We want to prove the THEORY correct because it is validated by the computer models.
So we should look for: "If the models behave like the theory suggests, THEN the theory is correct." Again, we want to prove that the theory is correct, not that the models are correct.
A. The correct answer does this.
B. Tempting, but this reverses the relationship, and uses the truth of the theory to prove the computer models are correct. Eliminate.
C. Models discovering something in the future??? Scope --> Elim.
D. Again, scope! is this even discussed? Elim.
E. We dont know what happens when errors are found because we arent told. Elim.
If you were stuck between A and B but didnt see the causal relationship, you could have also picked up on the subtle word changes.
The passage says: Scientists concluded there is "GOOD EVIDENCE" that the theory is correct.
(A) says "...then that theory is 'PROBABLY' correct.
(B) says "...'IS' correct"...
