(C) With accounts of various ancient writers used for a basis
(D) By the accounts of various ancient writers they used
(E) Using accounts of various ancient writers
Answer for the 1st one: E
A has a dangling modifier. Only the sketchy picture is based on the accounts and not the scholars. B, C, D constructions are roundabout and not right.
Am sorry for reviving a very old question, but I didnt understand this solution. how is "Based on" a dangling modifier, while "using" isnt?
-Vikram.

Answer pls!
The answer is B
ponram SaysThe answer is B
no...the answer is A
ajayreddy Saysno...the answer is A
I found 'B' as the answer in Powerprep. Besides, in choice A, the pronoun 'they' does not point to anything. If you have a diff explanation then plz describe.

Hi,
IMHO, the answer should be B , because in A, the "having gone..." should be modifying the "dangerous chemicals.." not "...the modern methods.." . Since the release of chemicals into the atmosphere should have been regulated/controlled, not the industrial methods that released them. Also, modern methods were not developed, chemicals were.
Also, as per Kaplan 800, if an action is ongoing, like in this case, "industrialization etc. have improved the living standards" , it is nowhere indicated that they have stopped improving the living standards, rather it is implied that they continue to do so, the present continuous tense is always better ....hence "introducing"..
a similar example for this Kaplan reasoning was Q1. in

I think the answer should be D since it maintains parallelism of the sentence.
What's the correct answer?

I think its B, but all of which creates conditions isn't this wrong?
OA pls

A. enabling trees to grow.
B. for the trees to grow.
C. for growing trees.
D. that enable the trees to grow.
E. that the trees can grow.
The correct ans is D. It's written that In choices B and C the preposition for is used unidiomatically. I am not sure why is that so. I had picked B.

for the paintbrush,
I think its A for the first one.. on the whole, THEIR seems ambiguous... not really sure if the choices are correct!
For the Forest Service,
think its C, HAD is required here!
OA pls?
and cud u pls let us know the source of these questions?
hi-
not sure for the first one ,
second one shud go with choice 'C'
vav83 SaysWhat's the difference between no one & none?
Here's my understanding of the difference between no one and none - Correct me if I am wrong!.
1. "None" can be treated both as a plural and as a singluar noun, however, no one is always treated as a singular noun.
Eg: No one knows the contents of the box.
Eg: None know the contents fo the box.
2. Also, no one is used to refer to people while none can be used both for people and for objects.
Eg: None of the universities are good.
Eg: No one of the universities are good. (Incorrect statement).
Further, the answer to the question
People can debate the aesthetic merits of these overwrought, disquieting, sometimes gruesome works of art, but no one can dispute their creators' mastery of the paintbrush as a blunt instrument.
A. but no one can dispute their creators' mastery of the paintbrush as a blunt instrument.
B. but none can dispute their creators' mastery of the paintbrush as a blunt instrument.
C. but not a one can dispute their creators' mastery of the paintbrush as a blunt instrument.
D. but no person can dispute their creators' mastery of the paintbrush as a blunt instrument.
E. but none can dispute to their creators' mastery of the paintbrush as a blunt instrument
would be B because B is more consise and because "none" is the plural form. If you had chosen "no one", then u are limiting the discussion to a "singular" person rather than to generalize the discussion to a plurality.
In general, on the GMAT, prefer none to no one.
PS and Disclaimer: These are my interpretations of the same and can and most probably will be wrong! :)

For the Forest Service,

No. "HAD" is not required here.. "HAD" needs to be used only when the action referred to happens before some other action. The action referred to here happens after the previous action and hence a simple past tense would suffice. Further, C uses "quicker" which is less grammatically correct than "more quickly" (In my opinion, quicker is more a slang, and hence on the GMAT, "more quickly" should be preferred). Hence the correct answer would be D.
