Confused about OG-72

Large national budget deficits do not cause large trade deficts. If they did, countries with the largest budget deficits would also have the largest trade deficits. in fact, when defict 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?

A Countries with large national budget deficts tend to restrict foreign trade.

B Reliable comaprisons of the deficts figures of one country with those of another are impossbile.

C Redusing a  country's national budget deficit will not necessarily result in a lowering of any

trade deficit that country may have

D When countries are ordered from largest to smallest in terms of population, the smallest countries generally have the smallest budget and trade deficit

E Countries with the largest trade deficits never have similarly large national budget deficits

Dear XDJM, could you explain the meaning of the text above? What does "If they did" mean?

I can hardly figure out the meaning of 题干。

谢谢先！

大虾，我觉得应该是“当这些赤字被调整到不同的国家有可比性时，便不存在这种关系“这种关系是指第一句话所说的大的国家预选赤字没有引起大的国家贸易赤字。 而非您说的--- 预算赤字导致贸易赤字。

您觉得呢？

lawyer_1,

我不太明白文章最后一句：In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation.

这里，deficit figures是指budget deficits and trade deficits还是指trade deficits? 此句和文章结论的推理关系？

thx！

谢谢lawyer,

如果只把握结论就好了，你又是如何理解OG里E的解释;

Finally, it is consistent with the passage that countries with the largest trade deficits sometimes have similarly large budget deficits (choice E).
