想請教大家 這篇的換句話說題

【The key factor in the success of these countries (along with high literacy,
which contributed to it) was their ability to adapt to the international
division of labor determined by the early industrializers and to stake out
areas of specialization in international markets for which they were
especially well suited】.

選項B:
Aided by their high literacy rates these countries were able to claim key
areas of specialization within established international markets.

選項C:
High literacy rates enabled these counteis to take over international markets
and adapt the international division of labor to suit their strengths.

我用刪去法刪掉剩兩個, 但後來還是猜錯了(正解是B)..

想請教大家為什麼呢? 是我誤解了原題的意思嗎?

感謝幫忙...
