Answer 1

How can you drop a raw egg onto a concrete floor without cracking it?       

Answer 2

there are two ways to do so
1. take the egg in your hand and drop it from a very very small height like 2 or 3cm. the egg won't break
2. wrap the egg in a bubble rap. this way the egg won't break even if it is dropped on a concrete floor

then logically your answer is that a concrete floor cannot be cracked by dropping an egg onto it. egg shell is very easy to break but concrete is a very hard material
