Read the paragraph and answer the question.The cliffs above our beaches are rock; the sand upon our seashore is rock; the clay used in brick-making is rock; the limestone of the quarry is rock; the marble of which our mantel-pieces are made is rock. The soft sandstone of South Devon, and the hard granite of the north of Scotland, are alike rock. The pebbles in the road are rock; the very mould in our gardens is largely composed of crumbled rock. So the word [rock] in its geological sense is a word of wide meaning.-- Agnes Giberne (From The World's Foundations)What type of paragraph is this?a. descriptiveb. narrativec. exemplificationd. cause/effecte. comparison/contrast

As the name suggests, an exemplification paragraph develops the main idea presented in the topic sentence through examples. Those examples make the explanation or argument clearer and better supported. They also help make the paragraph itself and the text as a whole more interesting. In the case we are studying here, the author wishes to convey the idea that rock is everywhere, that everything is made of rock, and that "rock" is a broad term for that reason. She provides readers with as many examples as she can to show them her point is valid: "The cliffs above our beaches are rock; the sand upon our seashore is rock; the clay used in brick-making is rock; the limestone of the quarry is rock; the marble of which our mantel-pieces are made is rock. The soft sandstone of South Devon, and the hard granite of the north of Scotland, are alike rock. The pebbles in the road are rock; the very mould in our gardens is largely composed of crumbled rock." Those examples develop the main idea, showing that rock is indeed everywhere.
