　　At one time it was thought that these matrix grains might be pristine nebular dust, the sort of stuff from which chondrules and inclusions were made. However, detailed studies of the chondrite matrix suggest that much of it, too, has been formed by condensation or melting in the nebula, although minute amounts of surviving interstellar dust are mixed with the processed materials.

关于对matrix成因的解释，没有说明consists mainly of grains of nebular dust that were trapped inside the meteor before they could be melted.

而且选项的说法好像是和chondrites的形成混了

最好把文章和问题都贴过来，这样比较好看~
