逻辑归纳题一个疑难

8. Large national budget deficits do not cause large trade deficits. If they did, countries with the largest budget deficits would also have the largest trade deficits. In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation. If the statements above are all true, which of the following can properly be inferred on the basis of them?

B) reliable comparisions of the deficit figures of one country with those of another are impossible.

自由的疑问:为什么B不对呢?

另外there is no such correlation指什么联系呢?感谢大家的帮助

我想问题就处在了reliable comparisions 上面吧
因为只有when deficit figures are adjusted 之后,这种赤字的数据才是有可比性的
而调整本身就是不一定可靠的啊,而且这种结果还取决于双方,如果你调了,而我不调,结果又不一样了

correlation是指有最大的预算赤字就会有最大的贸易逆差
