Question: Given the background: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. and the situation: Two sister villages, both situated near volcanoes, experience daily earthquakes. Green village started recording an increased size and number of earthquakes one day. Blue village didn't experience a change in the number of earthquakes. Answer the following question: Which village started experiencing less ground shaking?
Answer: Blue

[Q]: Given the background: When wind waves approach to coast area from deep water, the waves change their heights and lengths. The wave height becomes higher and the wavelength becomes shorter as the wave velocity is slowed when ocean waves approach to the shore. If the water depth is sufficiently shallow, the wave crest become steeper and the trough gets broader and shallower; finally, the ocean waves break at the shore. The motions of wave breaking are different with along to the steepness of shores and waves, and can be categorized by below three types.[11][12] and the situation: The tourist village had two beaches: Coral beach with nice sand and deeper water was preferred by families, and Surfer beach which had shallow water was a surfer's heaven.
