times that of the lesser earthquake.
B. The earthquake of greater magnitude has a seismographic reading that is 
times that of the lesser earthquake.
C. The earthquake of greater magnitude has a seismographic reading that is 100 times that of the lesser earthquake.
D. The earthquake of greater magnitude has a seismographic reading that is 10 times that of the lesser earthquake.
