Explanation:

A bridge is simply put one or two sentences used to connect the hook and the thesis statement, so that the whole essay runs smoothly.
You would use a bridge sentence to create a smooth transition in your introduction, so that no sentence is out of place. A bridge sentence needs to refer to both the hook and the thesis statement, so that it connects them in a nice manner.
