31. contemporary buildings display the new trends in earthquake engineering. using designs and materials that are more flexible allows buildings to absorb some seismic activity without collapsing. earthquakes frequently vibrate buildings off their foundations, so todays buildings are separated from their foundations, sitting instead on steel beams that rest on padded bases in the ground. the foundation absorbs the majority of the shock without transferring it to the building. the impact of the shock is \na prolonged b restricted \nc justified d intensified

Answer

Brief Explanations:

The text describes how modern buildings are designed to separate from foundations and have foundations absorb shock. This implies that the impact of the shock on the building is limited. "Restricted" means limited or kept within certain bounds, which fits the context. "Prolonged" means extended in time, "justified" means having a good reason, and "intensified" means made more intense, none of which match the idea of shock - absorption reducing the shock impact on the building.

Answer:

B. restricted
