No small countries and no countries in the southern hemisphere have permanent seats on the United Nations Security Co...

@jebharter,

Great question. I recommend figuring out as much as you can before
looking at the answer choices. Since this is a must be true question,
there are deductions you can make from the stimulus.

In this stimulus, we have a series of conditional statements

SC - >/PS

SH - >/PS

PS - >I and G

(/I or /G - >/PS)

I - some - A

We can combine all of these together

PS - >I - some - A
PS - >/SC
PS - >/SH
PS - >G

This diagram shows us what we can deduce from the conditional
statements in the stimulus and will allow us to parse through the
answer choices quickly.

(E) says, "Some countries that are in favor of a greater role for the
United Nations in moderating regional disputes are not located in the
southern hemisphere."

We can conclude (E) by combining the two "all" statements

PS - >G
PS - /HS

G - some - /HS

Thus, (E) is the correct answer choice.

I recommend figuring out as much as possible before looking at the
answers so that the wrong answer choices are easily identifiable as
incorrect and the correct answer choice jumps out to you. Also, you'll
find that there will be questions in which there is only one major
inference to figure out, and that inference ends up being the correct
answer. Doing this work up front will help you save time on these
types of questions.

Does this make sense? Let us know if you have any other questions!

Hi @Ravi,
I'm wondering how we can combine
PS --> I and
I --some-- A
into
PS --> I --some-- A

I thought the arrow had to point away from the quantifier.

If we had PS --> I, we could only convert it into either
not I --> not PS
or
I --some-- PS
which isn't combinable with
I --some A

Thanks.
