There ARE four flowers in the vase

There ARE four flowers in the vase.
There IS not one cloud in the sky.
There IS a puddle on the floor.
There ARE cookies in the jar.
There IS a lamp in my bedroom.
There ARE kids playing in the playground.
There IS a tree in our garden.

There are two chairs in the first picture.
There is one chair in the second picture.

How many ……… are there?
