In what way were ming china and tokugawa japan similar? (i have one shot at this so be ) a. they were both ruled by the mongols. b. they were both isolationist and limited contact with outsiders. c. they were both ruled by shoguns and emperors had little power. d. they were both contolled by powerful diamyos that converted people to sunni islam.

The correct answer is B. They were both isolationist and limited contact with outsiders.
Japan is known for its isolationist nature which lasted for a very long time, but Ming China also employed that technique - both countries wanted nothing to do with the outside world for a very long time. A is incorrect because Japan was victorious in their war against the Mongols; C is incorrect because shoguns were Japanese rulers and had nothing to do with China; daimyos ruled only in Japan and had nothing to do with Sunni Islam - Japan is predominantly a Buddhist/Shinto country.
