问题 Nowadays, scientists still have not made huge progress on the research of earthquake because they have not fully understood what cause earthquakes.
If the pressure on the fault is higher than the force of friction between different blocks or rock, the blocks of rock will ______.

选项

答案suddenly snap forward

解析 由题干中的force of friction定位到第三个小标题下末段末句If the pressure increases to a high enough level,...the force of the friction,and the blocks will suddenly snap forward.此处需填入谓语。题干问当断层上的压力高于摩擦力时将要发生的情况,题干中pressure...is higher than the force of friction与文中pressure...will overcome the force of friction属同义转述。故可知答案。
