We know that the situation involves making choices with five sentences. We use the fundamental counting principle to find the number of ways to form different five-sentence paragraphs. Multiply the number of choices for each of the five sentences. That is, $1\times 3\times 2\times 1\times 1=6$ Hence, there are 6 different ways to form different five-sentence paragraphs.
