At one point, she believed GMAT wasn’t for her. After scoring 595, self-doubt crept in and she questioned her potential. But instead of quitting, she made the right strategic changes. The result? A remarkable comeback to 695. Check out how Saakshi did it.

Recent investigations of earthquakes have turned up a previously unknown type of seismic shock, known as a displacement pulse, which is believed to be present in all earthquakes. Alarmingly, high-rise buildings are especially vulnerable to displacement pulses, according to computer models. Yet examination of high-rises within cities damaged by recent powerful earthquakes indicates little significant damage to these structures.
Which one of the following, if true, contributes to a resolution of the apparent paradox?
(A) Displacement pulses travel longer distances than other types of seismic shock.
(B) Scientific predictions based on computer models often fail when tested in the field.
(C) While displacement pulses have only recently been discovered, they have accompanied all earthquakes that have ever occurred.
(D) The displacement pulses made by low- and medium-intensity earthquakes are much less powerful than those made by the strongest
earthquakes.
(E) Computer models have been very successful in predicting the effects of other types of seismic shock.

I feel it should be C over B as that option explains that since these shocks were already a part of earlier earthquakes, the buildings were made taking these shocks into consideration. Also, this choice further states why there is little damage to the these buildings.
Pls help!

This is a paradox question. The paradox is that even though the computer models predict the displacement pulse to cause significant damage to the high-rise buildings, in actuality the powerful earthquakes caused little significant damage to these buildings. So we need an option that justifies why we would see significant damage in the computer models but not in the actual scenarios.
A. Incorrect. This does not help resolve the paradox as whether or not the pulse travels long distance doesn't tell why the damage is not present in the actual scenario.
B. Correct. This tells us a difference between computer models and real-life scenario. Note how this option does not negate any information in the passage. It helps justifies both sides of the paradox.
C. Incorrect. First of all, the information in this option is already present in the passage. Also, if this pulse is present in all earthquakes, it doesn't explain why the high-rise buildings aren't as vulnerable to these. Even if the buildings were made taking this pulse into consideration, it still doesn't explain why the models are predicting damage. This would make B an even stronger contender.
D. Incorrect. We're only concerned about the powerful earthquakes and those would still have stronger pulses. This doesn't help resolve the paradox.
E. Incorrect. We're not concerned about other types of seismic shocks. This is irrelevant.
Hope this helps!
