Freda is speaking to a group of college students about investing. “it is the time to get an ira when you reach an aae of $30,000.” this is ineffective because college students do not like acronyms. this is effective because she will appear knowledgeable. this is effective because these are terms used in that field. this is ineffective because of the principle of appropriateness to audience.

1) 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. which statement about this paragraph is accurate?
