Ablation Rates for Three Elements in<br/><br/>Cosmic Dust, by Dust Source<br/><br/>**Element** **SPEC** **AST** **HTC** **OCC**<br/><br/>**iron** **20%** **28%** **90%** **98%**<br/><br/>**potassium** **44%** **74%** **97%** **100%**<br/><br/>**sodium** **45%** **75%** **99%** **100%**<br/><br/>Earth's atmosphere is bombarded by cosmic dust originating from several sources: short-period comets (SPCs), particles from the asteroid belt (ASTs), Halley-type comets (HTCs), and Oort cloud comets (OCCs). Some of the dust's material vaporizes in the atmosphere in a process called ablation, and the faster the particles move, the higher the rate of ablation. Astrophysicist Juan Diego Carrillo-Sanchez led a team that calculated average ablation rates for elements in the dust (such as iron and potassium) and showed that material in slower-moving SPC or AST dust has a lower rate than the same material in faster-moving HTC or OCC dust. For example, whereas the average ablation rate for iron from AST dust is 28%, the average rate for<br/><br/>Which choice most effectively uses data from the table to complete the example?
