解释：
老师你好，这道题目C选项是不是不正确，因为higher credit rate 不是意味着lower credit quality嚒，正是因为质量不好，我才要求高回报率，这个理解对吗，谢谢解答
没明白C的含义？这两个半句分别什么意思？
If the mestic saving base of a country is stronger, the ability to issue bon in loccurrenis weaker. The higher cret rating typically means higer cret quality anlower cret risk cret rating agencies. C is correct. The cret rating agencies assign ratings to bon anthe highest rating means highest cret anlowest cret risk. Cret rating agencies make a stinction between bon issuein sovereign's loccurrenanbon issuein foreign currency. Thus the loccurrenaffects the cret rating of the sovereign bon. The nationgovernment of a country will issue the loccurrenbon easier if the mestic saving base is stronger.这道题的意思能下吗？考点是什么？
A为什么不对呢，就是有little不同啊。。。
