Meteorites from Antarctica are an important area of study of material formed early in the solar system; most are thought to come from asteroids, but some may have originated on larger planets. The first meteorite was found in 1912, and named the Adelie Land meteorite. In 1969, a Japanese expedition discovered nine meteorites. Most of these meteorites have fallen onto the ice sheet in the last million years. Motion of the ice sheet tends to concentrate the meteorites at blocking locations such as mountain ranges, with wind erosion bringing them to the surface after centuries beneath accumulated snowfall. Compared with meteorites collected in more temperate regions on Earth, the Antarctic meteorites are well-preserved.
What is the supposed source of most Antarctica meteorites?
asteroids

It also used to be commonplace to have a team play an exhibition against Minor League affiliates during the regular season, but worries of injuries to players, along with travel issues, have made this very rare. Exhibitions between inter-city teams in different leagues, like Chicago's Crosstown Classic and New York's Subway Series which used to be played solely as exhibitions for bragging rights are now blended into interleague play. The annual MLB All-Star Game, played in July between players from AL teams and players from NL teams, was long considered an exhibition match, but as of 2003 this status was questioned because the league whose team wins the All-Star game has been awarded home field advantage for the upcoming World Series.
What concerns have reduced Minor League exhibition games?
worries of injuries to players, along with travel issues

Rothko also began using the new synthetic pigments, but not always with happy results. In 1962 he donated to Harvard University a series of large murals of the Passion of Christ whose predominant colors were dark pink and deep crimson. He mixed mostly traditional colors to make the pink and crimson; synthetic ultramarine, cerulean blue, and titanium white, but he also used two new organic reds, Naphtol and Lithol. The Naphtol did well, but the Lithol slowly changed color when exposed to light. Within five years the deep pinks and reds had begun to turn light blue, and by 1979 the paintings were ruined and had to be taken down.
What was the result of the change in color in the Rothko Passion of the Christ murals?
ruined and had to be taken down
