Earth's crust is made up of relatively rigid plates that ride atop earth's hot, semiliquid mantle. (2) the plates are called tectonic because they're in constant motion. (3) they can move because earth's mantle is a very hot and semiliquid fluid called magma. (4) volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) therefore, we often find volcanoes and earthquakes along plate boundaries. (7) plates may also collide. (8) when that happens, mountain ranges are formed. (9) for example, the collision of the plate carrying the indian subcontinent created the himalayan mountains when it collided with the asian plate. 8. which sentence in this passage introduces a new topic that might begin a new paragraph?

Read the excerpts from “take the tortillas out of your poetry” and “speaking arabic.” my friend had concluded that if he took his language and culture out of his poetry, he stood a better chance of receiving a fellowship. he took out his native language, the poetic patois of our reality, the rich mixture of spanish, english, pachuco and street talk which we know so well. in other words, he took the tortillas out of his poetry, which is to say he took the soul out of his poetry. at a neighborhood fair in texas, somewhere between the german oom-pah sausage stand and the mexican gorditas booth, i overheard a young man say to his friend, “i wish i had a heritage. sometimes i feel—so lonely for one.” and the tall american trees were dangling their thick branches right down over his head. which best states how the structures of both excerpts support ideas about cultural diversity? each incorporates non-english words. each incorporates academic words. each incorporates offensive words. each incorporates nonsense words.
