原题？？？全文太长了吧。。。。题干的话是下面的。。。 Studies of the Allende meteorite provided information about the composition of chondritic meteorites and their possible origin.

Answer Choices
O       When Allende entered Earth's atmosphere, it broke into thousands of pieces called chondrites because they look like glassy, black seeds.
O       The mineral content of chondrules suggests that they were probably formed in isolated regions of the nebula that remained much hotter than the rest.
O       Chondrules are tiny, millimeter-sized drops of silicate materials that probably formed when lumps of nebular dust were fused at extremely high temperatures and then quickly cooled.
O       Irregularly shaped inclusions in Allende are composed of minerals that are resistant to melting and are believed to be the earlest minerals to have condensed out of the nebula.
O       The matrix that holds the chondrules and inclusions together in Allende consists mainly of grains of nebular dust that were trapped inside the meteor before they could be melted.
O       Except for being depleted in volatile elements, chondritic meteorites are probably very similar in composition to the matter from which planets were assembled.

这道题我看了。我的看法是第二种正确

The mineral content 这句isolated region原文没有提到过，而且他仅仅指出了 mineral content形成处更热，而这只是原文第三段后半部分的一个细节推论。

The matrix 这句更是与原文相悖，并不是未能融化的dust，而是经压缩与融化形成的
