Hi All,
In CR answer choices, i came across choices that start with the words "Some" & "Not all...."
1) "Some..." (ex: Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft. )
2) "Not all.." (ex: Not all tourists who come to Tenare Island enjoy swimming or surfing).
Could you please give me clarity on how to interpret words like "Some" & "Not all...."
What is the logical way to quantitative that? (does it mean >1% (or) 50% or 90%...)
Please advise.
thank you,
Naps
Hello,
Naps. Unfortunately, there is no way to quantify either
some or
not all, except to say that in the former case,
some refers to more than one, while in the latter,
not all could mean everything or everyone except for a single outlier. You would need more information to tack a number onto the expression. Looking at the two sentences you provided above, we can glean the following:
1)
Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft.
Meaning: More than fullerene has been found on the remains...
2)
Not all tourists who come to Tenare Island enjoy swimming or surfing.
Meaning: At least one tourist who visits Tenare Island does
not enjoy either swimming or surfing. This might be
some tourists, but it could be just one. Note the difference.
I hope that helps a bit. I know such vague language can be vexing, but believe it or not, learning about it now may help you not only on the Verbal portion of the test, but also on certain Quant problems (where there may be more numerical information to lean on).
Good luck with your studies.
