问题     Arctic sea ice comes in two varieties. Seasonal ice forms in winter and then melts in summer, while perennial ice persists year-round. To the untrained eye, all sea ice looks similar, but by licking it, one can estimate how long a particular piece has been floating round. When ice begins to form in seawater, it forces out salt, which has no place in the crystal structure. As the ice gets thicker, the rejected salt collects in tiny pockets of brine too highly concentrated to freeze. A piece of first-year ice will taste salty. Eventually, if the ice survives, these pockets of brine drain out through fine, veinlike channels, and the ice becomes fresher; multiyear ice can even be melted and drunk.
In the context in which it appears, “fine” most nearly means
选项 A、acceptable
B、elegant
C、precise
D、pure
E、small
答案E
解析 根据文章第七句，fine与veinlike并列。veinlike意为“像血管一样的”，即“细小的”，因此fine与之同义，选项E正确。
