Question

The sound of a bird is more__________ than that of a lion.

Answer 1

1. The pitch or shrillness means the thickness and thinness of sound.
2. Higher the pitch thin will be the sound and the smaller will be the pitch thicker will be the sound.
3. The sound produced by birds has a higher pitch so they produce a thin sound whereas the sound produced by a lion is of low pitch, therefore lion produces a thick sound.

Hence, the sound of a bird is more shrill than that of a lion.
