This large collection of meteorites allows a better understanding of the abundance of meteorite types in the solar system and how meteorites relate to asteroids and comets. New types of meteorites and rare meteorites have been found. Among these are pieces blasted off the Moon, and probably Mars, by impacts. These specimens, particularly ALH84001 discovered by ANSMET, are at the center of the controversy about possible evidence of microbial life on Mars. Because meteorites in space absorb and record cosmic radiation, the time elapsed since the meteorite hit the Earth can be determined from laboratory studies. The elapsed time since fall, or terrestrial residence age, of a meteorite represents more information that might be useful in environmental studies of Antarctic ice sheets.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How do the meteorites found in Antarctica add to knowledge about the solar system?
Ah, so.. better understanding

During the Three Kingdoms period of ancient China, there was constant warfare occurring in the Central Plain of China. Northerners began to enter into Fujian region, causing the region to incorporate parts of northern Chinese dialects. However, the massive migration of northern Han Chinese into Fujian region mainly occurred after the Disaster of Yongjia. The Jin court fled from the north to the south, causing large numbers of northern Han Chinese to move into Fujian region. They brought the old Chinese spoken in Central Plain of China from prehistoric era to 3rd century into Fujian. This then gradually evolved into the Quanzhou dialect.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What disaster caused a massive migration in the Fujiian region?
Ah, so.. the Disaster of Yongjia

The urban AC stations resemble soft AC rather than hot AC; they play predominantly R&B and soul music with little hip-hop. This is reflected in many of the urban AC radio stations' taglines, such as "Today's R&B and classic soul", "The best variety of R&B hits and oldies" and "(City/Region)'s R&B leader". Urban AC's core artists include Luther Vandross, Trey Songz, Patti LaBelle, Toni Braxton, Whitney Houston, Aretha Franklin, Frank Ocean, Craig David and Mariah Carey.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What other adult contemporary radio format is urban AC similar to?
Ah, so..
soft AC
