Is the number of sellers in the market the only thing that is different in each of the four market types economists study?

What will be an ideal response?

No, the number of sellers is not the only factor that differs; the degree of similarity of each firm's product also plays a role. For instance, in a perfectly competitive market, each firm sells an identical product whereas in a monopolistically competitive market, each firm sells a slightly different product.
