shakes．To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens．One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the time．During small earthquakes，faults rupture(斷裂)at about kilometers per second．During bigger quakes，however，ruptures can happen at rates faster than kilometers per second．At such high speeds．massive amounts of pressure build up，generating underground waves that can cause more damage than the quake itself．Lucky for San Francisco，these pressure pulses(脈沖)travel away from the city during the 1906 event．As bad as the damage was，it could have been far worse．Looking ahead，scientists are trying to predict when the next major quake will occur．Records show that earthquakes were mon before 1906．Since then，the earthquake has been relatively quiet．Patterns in the data，however，suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent．New buildings in San Francisco are quite safe in case of future quakes．Still，more than 84 percent of the

nest．This behavior is interesting to scientists，who wonder how ants know for sure and so soon that another ant is dead．DongHwan Choe，a scientist at the University of California found that Argentine ants have a chemical on the outside of their bodies that signals to other ants．“I39。s telling other ants that it39。m dead．”the other set says，“I39。s because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new unique chemicals after death，”said Choe． When other ants detect the“dead”chemical without the“not dead yet”chemical，they haul away the body． This was choe39。m dead”chemical on their bodies．38．According to Choe39。s hyothesis?A．It shows that his hypothesis is wrong．B．It proves that his hypothesis is convincing．C．It
