Civil Service Exam Reviewer · Ordering of Sentences · hard

Arrange the following sentences to form a coherent paragraph, then choose the correct order: (1) This movement displaces a huge volume of water above it. (2) The displaced water then spreads outward as a series of long waves. (3) Not every earthquake produces a tsunami. (4) An earthquake typically causes one only when the sea floor itself is suddenly lifted or dropped. (5) That is why coastal residents are told to move to high ground after a strong quake, even if the sea looks calm. (6) In deep water these waves may be barely noticeable, but they grow taller as they approach shallow coasts.

4-3-1-2-6-5
3-1-4-2-6-5
3-4-1-2-6-5
3-4-1-2-5-6

Answer

C. 3-4-1-2-6-5

Solution

The correct order is 3-4-1-2-6-5. Each sentence picks up an idea from the one before it: Not every earthquake produces a tsunami. An earthquake typically causes one only when the sea floor itself is suddenly lifted or dropped. This movement displaces a huge volume of water above it. The displaced water then spreads outward as a series of long waves. In deep water these waves may be barely noticeable, but they grow taller as they approach shallow coasts. That is why coastal residents are told to move to high ground after a strong quake, even if the sea looks calm. Each wrong choice swaps just one pair of neighboring sentences, which breaks one of these links.
