It's straight E. We don't know the change in gross domestic product from 1985 to 1994.

Answer: E.

This is a 2-by-2 question that frequently appears in the GMAT Math.
There are 4 variables (a, b, c and d) in the original condition and the question. In order match the number of variables to the number of equations, we need 4 equations. Since the condition 1) and the condition 2) each has 1 equation, there is high chance that E is the correct answer. In fact, using both the condition 1) and the condition 2), the correct answer is E.
