In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. Earthquakes are the shaking and moving of the ground when energy is released in waves.   P. These waves are similar to ocean waves, which move through water. Q. These waves are called seismic waves.  R. Seismic waves, however, move through the ground. S. Earthquakes can also be caused by other natural events, such as landslides and volcanoes.  6. Manmade earthquakes happen because of nuclear testing and mining explosions.
