Dear Mehran I just want to make sure the following about this question: LP ====> IPS & SO LP ====> ICV Therefore, ICV <==== LP =====>IPS & SO ICV <=== LP <==Some==>IPS &SO ICV <===Some===>IPS & SO I understand this logical flow. But, I am not pretty sure that "Some A and Some B are C" could be interpreted as "Some A are C" and Some B are C" separately, which lead to the answer A. I have thought that if " A and B are C," those A and B should not be separately connect to C. Therefore, "A are C and B are C" is logically wrong. Am I misunderstood? Many thanks,

    Is "A<====some=====>B & C " logically means " Some B are A & Some C are A" so, we can conclude separately "Some B are A" or "some c are A"? Plz, help me out with your explanations...

    Remember, "and" is a conjunction. Therefore, Some A and Some B are C can be split into Some A are C and Some B are C. So we'd write it out: PLP-some-GI GI-some-PLP PLP-some-SO SO-some-PLP PLP ==> ICV not ICV ==> not PLP We can arrange like so: GI-some-PLP ==> ICV and SO-some-PLP ==> ICV Therefore, we can infer: GI-some-ICV ICV-some-GI and SO-some-ICV ICV-some-SO (A) is our correct answer because it is the second option. By arranging like so: SO-some-PLP==>ICV we can conclude SO-some-ICV. Hope this helps! Please let us know if you have any other questions.

    I dont get where the word "some" comes from in the passage

    Okay, so we are told that "those who participate in local politics include people who are genuinely interested in public service and people who are selfish opportunists." So, what does that mean? It means that a specific group is made up of two kinds of people. We don't know how many of each, or whether they overlap. So, we can only infer that some people who participate in local parties are genuinely interested in public service, and some of them are people who are selfish opportunists. That's where the "some" comes in. Hope that clears things up! Please let us know if you have any other questions.
