In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. B: The sound source creates vibrations in the surrounding medium.  C: The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. D: Sound can propagate through a medium such as air, water, and solids as longitudinal waves and also as a transverse wave in solids.

The correct answer is option 1) i.e. DCBA.

  • D is the first sentence because it initiates the subject of propagation of sound, which is talked about further in the passage.
  • C mentions the source of the 'sound wave'. It is already mentioned in D that sound can propagate was a transverse wave. So, C would follow D.
  • B says that sound creates vibrations and A further explains how the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. So, A is the continuation of the point mentioned in B. So, A comes after B.
