can someone explain in more simple terms the difference between E and D?

@ajwarren20015

How do I ensure I have correctly selected the conclusion rather than the sub conclusion/major premise? I thought this question was a trap because it had the conclusion in the last sentence and in turn thought the sentence saying there is a crucial distinction was the conclusion

i am confused because answer E says some and wouldn't it be all of those of those countries are not in the southern hemisphere?
