B ??

Don't listen to Dave. Damon was right, the answer is D. I just took the test. I got this answer wrong thanks to Dave, but Damon is right. The answer is D, the intensity of the earthquake.

Its a I just did a test and i did A. And i remember learning about it in school.

OMG!!! WHAT IS DA ANSWER!!!!! POTATOESSSSSSSSSSSSs

the answer is D trust me it proven!!

Omg this had become more and more confusing! sacgshdavsauhsd I don't know lol Who here goes to connexus ?

Since it might be different for everyone the answer is:

The intensity of the Earthquake

I know nothing about this science but do not understand why intensity would impact my triangulation to find the location.

You are right it is B.

P.S. I got the question right.

What is the answer?
