This is a test of commonsense with single/multi-choices. Complete the next sentence:

How to get away with smoking inside
Wait until night.
Why? If you act as if you are going to bed, there is a less chance of your parents bothering you, and they won't be in your room for the rest of the night.
Get a blanket.

Pick from:
*Put it in the spacing between the bottom of the door and the floor. This will make it so that smoke won't escape from your room into the rest of the house.
*Get one that has an hood and covers so it will look as dark as the room to your parents, who will be going to sleep and will not bother you quietly. This way, they will not see that you are smoking inside.
*If your parents would prefer to smoke outside, it's always best to get a blanket. You can also have them bring you something fancy.
*If it is cold in your house, get one that is big enough to cover all your stuff. Say the name of the person you are smoking cigarettes with silently, so that they have no reason to call.
The answer is:
Put it in the spacing between the bottom of the door and the floor. This will make it so that smoke won't escape from your room into the rest of the house.
