Is it true, that in the GMAT concept, the word "some" means "at least one to ALL" ?
Also, the same question but for "most". Does most, which obviously mean more than 50%, also mean more than 50% to ALL?
I am taking a course with some company, and they consider "some" as to any number between at least 1 to ALL.
It sounds weird that "some" can refer to all.

Thank you!

Some : 1 to 99
None: 0
All: 100
not all: 0 to 99
most: >50%
less<50%

in negate of none: you can assume Some
in negate of some: you can assume none
In negate of all: you can assume not all
in negate of most: less than half
in negate of less: more than 50%( 51% to 100%)

I am afraid I didn't understand what you meant.

Could you just simply answer my question, please?

Thanks!!

Yes, "some" does mean "at least one" in logic. Though we use it in spoken English to mean "a few", in logic it does translate to "at least one". It could very well be "all". We just don't know.

When I say:
"Some of my friends will come."
It means that at least 1 will definitely come and more could come and even, all could come - I just don't know. I do know about at least 1 that he is coming.

Thank you ma'am!

I have sent you a PM but I guess posting here will be better since it can help other students as well.

So,

regarding those indicators,

For example, the phrase "either...or", while in real life means x or y, is considered "at least 1, possibly both" in the GMAT world.
Also, the word "most" means "more than 50% to ALL".

It appears that all of these indicators are used differently on the GMAT than how they are used in the real world.

How am I supposed to know what words are used differently on the GMAT, and what are those words?

I am a bit confused.

Thank you!

Yes DanielEMZ,

Posting here is the best since it could help others too and also, I keep an eye on this thread and my PS thread.

As for the difference between 'GMAT world' and 'real world' - there isn't a whole lot. The terms you mentioned are used this way in the study of logic. Logic says that each term means exactly what it means and there is no other implication it has. The rest is a case of unknowns. GMAT is a test of logic and hence you need to know how these terms are used.

So out of 100 people, I survey 60 and find that they all like vanilla ice cream more than chocolate ice cream. I can say that out of these 100 people like vanilla more. Perhaps if I survey the other 40, I may find that they like vanilla more too. That doesn't make my previous statement false. Hence, most means more than 50% and COULD be all too.

Hmmm.. I see. We are basically manipulating or, more accurately, aren't taking responsibility for what may be true and we don't know if it is indeed.
Kind of CYA.

What about "either ... or" ? Could you provide an example that shows the meaning of this phrase (in the context of "at least 1, possibly both"), please?

You are very helpful.

Kudos!

Either ... or... means at least one will be true but both can be true too (when both can co-exist)

I am either exhausted or sick.
- Means I am at least one of the two since I am not feeling well. It is possible that I am both exhausted and sick.

What colour ink does the pen have? Either blue or black.
You know that it will have only one type of ink and it will be one of the two - blue or black. Nothing wrong here.

Hi Ma'am,
I have a doubt similar in nature. I have read that "little" means zero E.g. he offered me little help....meaning he did not offer me any help. Similarly "a little" means some value. Does the same concept apply to GMAT as well?

Yes, "little" means "almost none". It could be "none" too.
'He offered me little help' is just a polite way of saying 'he offered me no help' or 'almost no help'.
'a little' means 'some'.

Similarly, few means 'almost none' and 'a few' means 'some'.

C : In some cases, we find that because X and Y may not have same relevant conditions so we can not determine the same outcome. ( as in above question) - not relevant as both subjects could have differences.


However in some case, it is mentioned that even X and Y may not have same relevant conditions but it gives a reasoning to think that it may happen. ( as in below question)- a general consideration


C : this is an example where the generalized conclusion is countered.

As in questions it is always asked MOST weaken or MOST strengthen , Is there any way that we can differentiate when to consider that X and Y may bring the same output and in what cases it should not be considered as general consideration.

Thank you so much for the clarification. It Helped a lot !

Hey itsSKR,
I have replied on the original post of the question (on which you tagged me). I have been running behind and it takes me a few days to get to all mentions but I will try to get to all.

Thanks a lot ma'm for the kind consideration.

Manufacturing plants in Arundia have recently been acquired in substantial numbers by investors from abroad. Arundian politicians are proposing legislative action to stop such investment, justifying the proposal by arguing that foreign investors, opportunistically exploiting a recent fall in the value of the Arundian currency, were able to buy Arundian assets at less than their true value.

Which of the following, if true, casts the most serious doubt on the adequacy of the Arundian politicians' justification for the proposed legislation?


Why A is not answer. I still don't understand why in E i should worry about how investors can earn profit. Please check my explanation below.

(A) The Arundian government originally welcomed the fall in the value of the Arundian currency because the fall made Arundian exports more competitive on international markets
So investors could buy in Arundian because price was competitive else investors wouldn’t have bought these plants at first place. So true value doesn’t matter but what matters is international market price if foreigners want to invest in some country.

(E) The true value of an investment is determined by the value of the profits from it, and the low value of the Arundian currency has depressed the value of any profits earned by foreign investors from Arundian assets.
>>We focus on investment and how much money Arundian could get . How investors earn profit is thereafter is none of our business. The current value of profits could be depressed but it doesn’t mean the company couldn’t change policies , align with investors vision , expand business in local market or start new business streams for high ROI.

VeritasKarishma ; please help me to understand this. i am kind of lost based on my above explanations. Whats wrong ?

Could you please show the differences between inference and assumption, giving sentence examples?

Thanks in advance!
