Most people are dependent on sights and sounds to accomplish virtually every daily activity. Emma, Zoe, and Sophie are deaf and blind, so they have come to rely on their to compensate for what they cannot see or hear.

Since Emma, Zoe and Sophie are deaf and blind; they can rely on their other senses to compensate for what they can't see or hear.

Explanation:

The Mighty God has developed human beings with five senses which help them to live and co-operate with their environment. These five senses are Eyes, Nose, Ears, Tongue and Skin.

One can see this beautiful world through his/her eyes, smell the fragrance or odour with nose, listen to the sound by ears, taste food or edible things by tongue and of course feel the environment and other beings by touching them and have sensations through the skin.

When any of these senses doesn't work properly, the other senses take charge more strongly and allow one to compensate with the environment.

So people who are blind and deaf like Emma, Zoe and Sophie may not see things or listen the sound but they can use their other senses like skin and nose to judge things and other beings, and compensate for what they can't see or hear.
