Read the following paragraph carefully and select the option which would correctly fill the blanks in the given order.

Sound is produced by vibration and different musical instruments have specific vibrating parts. In a X the sound is produced by stretched strings, in a Y it is the stretched membrane that vibrates and in a Z the vibrating part that produces sound is the air column.

X, Y and Z can respectively be :

  • A.sitar, harmonium, dholak
  • B.dholak, ektara, mouth organ
  • C.guitar, tabla, shehnai
  • D.ektara, violin, piano

Answer: C

X, Y and Z are guitar, tabla, shehnai.

A guitar produces sound from vibrating stretched strings, a tabla from its stretched membrane (the drum skin), and a shehnai, a wind instrument, from its vibrating column of air.

The other sets break the order. In option A the harmonium is a reed and air instrument and the dholak a membrane, both in the wrong places. Option B starts with the dholak, a membrane, where strings are needed. In option D the violin and piano are both string instruments, so neither can fill the membrane or air-column blank.
