OG有没有错?

OG SC
133全划线 答案 Holland spends a larger percentage of its gross national product on defending its coasts from rising seas than the United States does on military defense.
怎么会spend sth on doing sth ?难道不是spend sth (in)doing sth或spend sth on 名词?

139答案A The extraordinary diary of William Lyon Mackenzie King , prime ministerof Canada for over twenty years, reveald (that this most bland and circumspect of men was mystic guided in both public and )private life by omens,messages received at seances, and signs from heaven.
其中this most bland and circumspect of men我很不理解,adj+of men???

还有一个写作的细节问题,请问正式文体在逗号和句号后面是否需要空一格?我在word中打的时候不空会出红线.

谢谢

能帮我解释一下139题的意思吗?
打印时候当然没有红线,自动纠错有红线,所以我不知道考试时要不要逗号和句号后面空格
谢谢你

真是信息不对称,我是想问this most bland and circumspect of men was a mystic guided in ....这一段的中文意思是什么?而且还用了men这个复数名词,能麻烦帮我解释一下吗?太不好意思了,谢谢
