Archaeologists in Ireland believe that a recently discovered chalice, which dates from the eighth century, was probably buried to keep from being stolen by invaders.
to keep from
to keep it from
to avoid
in order that it would avoid
in order to keep from
but also 没搭配的not only ---排除DE
主语应该是scientists an historians,不是an attempt---排除CE
AB的区别
A:scientists an historians,插入语in their attempt,are hoping
谓语是hope---主要动作 状语---在他们的尝试里 不合逻辑;且attempt,明显做动词,而不是这里的名词
B:scientists an historians are attempting to do, hoping
谓语:尝试 伴随状语:希望 符合逻辑
