I got the chance to distinguish by inventing something (mercy) to catch the snakes.    No products can help me catch snakes, so I set out (research) the habits of snakes to trap them. I decided on three approaches: firstly, removing their habitat; secondly, (attract) them into  trap, and thirdly cooling them. I used the (freeze) bowl to make the snakes less active,  then collected them.
