Mongol rule in Russia and China differed in that
(A) in China, the Mongols maintained Chinese traditions of isolation from foreigners.
(B) Eurasian trade routes under Mongol protection connected Russia more than China to Western European trade routes.
(C) the Mongols became more involved in administration in China than in Russia.
(D) the Mongols were more interested in controlling trade in China than they were in Russia.
(E) Russia advanced culturally under Mongol rule while China became backward.
I would say (C) because the Mongols definitely made China less isolated, they were very interested in controlling trade in ALL of their territories, the Mongols were great cultural patrons in general, and (B) just seems ridiculous.
