Monika powerful tail does not mean a heavy tail and also birds need to have a powerful tail so that they can change the direction of their flight

Ans 11:

Hemanth from The Camford International School , Coimbatore
Class : Class 5
The correct option is D and I have proof:-Streamlined body of birds help them to move easily through the air while flying. It reduces the air resistance during flying.There are only a few muscles in the trunk and the tail, but they are very strong and are essential for the bird.Powerful = Strong

In the solution, they show that a strong tail is gonna hinder flight. Seriously, guys? It's a no brainer, and if it hasn't been taught in school, logical reasoning can be applied. Of course a strong tail would be heavier. Why not? If a person is strong, he is heavy. It's simple- more mass= more weight. Come on. Everyone knows this. It's just logic science!
