Which of the following most contributed to the cultural and scientific achievements of the song dynasty? a. the increased role of peasants in the bureaucratic system b. the weakening of the caste system c. the growth of traditional confucian ideas related to women's place in society d. the increase in food production that allowed more people to pursue education hurry! i need !

I would say the correct answer is D. The increase in food production that allowed more people to pursue education.
I don't think A is correct because peasants and the bureaucracy don't really have much to do with science or culture; B is also incorrect because the Song dynasty didn't have a caste system; C is incorrect because women at the time didn't really affect culture or science. This is why I believe D is the correct answer.

The answer is option a. boundary line drawn by pope alexander iv in 1493.
