hey,
i too felt that C should be the answer. i know that 'for guididng' sound a bit wrong, but in A it says 'herself an escaped slave'. That souns a bit incorrect.
mukul....u there buddy???? 
Please solve this!
Before the Civil War, Harriet Tubman, herself an escaped slave, returned again and again to Maryland to guide other slaves along the Underground Railroad to freedom.
(A) herself an escaped slave, returned again and again to Maryland to guide
(B) being an escaped slave herself, returned again and again to Maryland so as to guide
(C) an escaped slave herself, returned again and again to Maryland for guiding
(D) herself as an escaped slave, returned again and again to Maryland so as to be the guide of
(E) who had been herself as an escaped slave, returned again and again to Maryland for the guiding of
Guyz...put the pieces together and you get the answer...
so as to is WRONG!! atleast on GMAT
rest all are verbose...and awkward...
most of the times we ignore A and look for other options...
u see one thing here...a vertical scan will show u that A is the most concise....instantly it shud flash!! that hey A can be the answer...
after so as to...nothin is left to see...simply A
i got like 5 answerws A on my actual GMAT...jus imagine my worries!!

Thanks Mukul, for the analysis. :)
Mukul, by any chance do you have (or maintained) a list containing GMAT usages, like here 'so as to' is wrong GMAT usage, do you have any list? Or if not, could you post some of the usages, which can be wrong w.r.t. GMAT?
Thanks
While posting dubious problems...
(not exactly dubious but the problems that more than two persons got wrong answer)
please provide the reference source also.. (like 1000 SC #155)
sorry i initially made a promise that i d try post on this thread.. but guess i wouldnt :(
keep it up Praveen good work there.
Thanks aims :)
But it will be really good, if you could post questions which you found difficult. And yes next time i will post the source. 😃
Analysis for this one guys!! Mukul ??

You influence somebody or are influenced by somebody.
Gus please help me soleve his:
2 sub-commitees of 3 member each are to be formed from a 6 member commitee comprising of A, B and 4 others.
What is the chance that B gets staffed only on those commitees in which A is present.
My asnwer is 20%, correct answer 40%...........
Wording of the question may be slighly different from what I have written,
Thanks
What is the chance that B gets staffed only on those commitees in which A is present.
=>Baye's Theorem( occurence of 1 event given the occurence of another)
A is present on 5C2 committes = 10
A and B are present on 4C1 committees = 4
Hence 40%

Ok, I think this can be tricky...
I think where you might have gone wrong is that you considered the probability that A&B; will be in 1 same commitee.
The probabilty doubles because not including A&B; in commitee 1, automatically includes them both in commitee 2.
here is what I would do for such problems:
Probablity of A and B both being on the same commitee
= Probability of A&B; being in commitee 1 + Probability of A&B; being on commitee 2.
= (1x1x4)/6C3 + (1x1x4)/6C3
= 1/5 + 1/5 = 2/5 = 40%
Hope this makes sense :)

And this one also:
193) Byron possessed powers of observation that would have made him a great anthropologist and that makes his letters as a group the rival of the best novels of the time.
(A) makes his letters as a group the rival of
(B) makes his letters as a group one to rival
(C) makes his letters a group rivaling
(D) make his letters as a group the rival of
(E) make his letters a group which is the rival of
I think answer must be D.
powers of observation make someone somthing... Hence, choices A,B and C are wrong (they use makes). Out of D and E, E is wrong because there is no comma before "which"...also it kind of changes the meaning of the sentence...
Therefore D is correct.
Cheers!
Satish
Thanks guys,
but 
I had solved the problem, but i was absent mindedly adding up wrongly. here is my approach, very similar to Satish's (please point out if my approach is faulty, as that spells greater trouble)
Case-1:
A is on com 1 and B is with him: 4/5.4 (Why because if A's selected then the other two places can be filled in 5.4 ways, simlarly with A and B fixed, the third place can be filled in 4 ways)
Case2:
A is on com 2 and B is with him,: same as case-1 4/5.4
there fore total probability = 4/20 +4/20 = 8/20 =40%
I can't believe that I added 4/20 + 4/20 as 8/40 (I seriously deserve to give myself a break:wow: 
)
thanks......
TanBhai, it's E)None of these. Please follow mailsatk's post above:

hmm... actually the answer is 3 .....
heres the procedure let ( 9^1+9^2+.......+9^9)=a
so we have a/6 = a/( 2*3)
a=3x + 0, a= 2y +1 are the 2 eqn that u get
now using the chinese remainder theorem
2*a=6*x-----------1
3*a=6*y+3--------2
subtract 2 from 1 and u get a=6*(y-x)+3.... thus the answer is 3
For the first Q answer is B
You influence somebody or are influenced by somebody.
Affirmative!!

When arranging people in a group, using Permutations is a very bad idea
Consider A,B,C,D,E and F
A,B,C is the same as A,C,B . The order doesn't matter only the people in the group does. Therefore Combinations!!
For the second S.C answer A??
I make/You make/ We make
He makes
I'll make you do it/We'll make you do it/He makes me do it/ He makes them do it
His powers of observation make him a formidable opponent
Their powers of observation makes the group a formidable....
makes his letters

OMG!!!
I have done one of the worst mistakes and have realized it so late... :(
You are right, gabriel and all other who mentioned 3 as the answer. Where I went wrong with my analysis is that I considered that the remainder will remain unchanged even if I divide the numerator and denominator by a number...(I had divided by 3).
Infact that is not true. The remainder will change, although the final value of the fraction does not change. For e.g.
Consider 17/3. Remainder = 2.
(17x2)/(3x2) = 34/6. Remainder = 4.
See how the remainder doubled? It doubled because I multiplied 2.
Had I multiplied 3, the remainder would have been 2 times 3 = 6. You can try that.
I my previous analysis, I cancelled 3 from numerator and denominator... i.e., I divided both numerator and denominator by 3. In the end, I got the answer as 1. I should have now multipled 3 to this answer (because I previously divided). i.e., 1x3 = 3....which I did not do.
Sorry Puys for the silly mistake!! damn!! I just hate when this happens!!
But, anyways, I figured it out...so
Cheers!
Satish
OMG!!!
oye balle balle , i also got that right
SC's will now take them head on.......
Keep posting and ATB,
What is the reminder when 9^1 + 9^2 + 9^3 + ...... + 9^9 is divided by 6?
(1) 0
(2) 3
(3) 4
(4) 2
(5) None of these
I arrived at the answer rather differently
9^1 +9^2 = 9+81 = 90 which divided by 6 = 0
9^3 = 729 which divided by 6 leaves a remainder 3
So, for the first 3 numbers the remainder is 3 and there are 3 sets(9^1 + 9^2 + 9^3, 9^4 + 9^5 + 9^6, 9^7 + 9^8 + 9^9)
So I should get 3+3+3 = 9 which divided by 6 wld give me remainder 3
Then, I also realised another approach after the first step itself.
Since powers of 9 always end in 1 or 9, the sum of two consecutive powers will end in 0 and be a multiple of 6
So whatever was the remainder for the next power, would be the remainder for any n(where n is odd)
yeah...gud approach there...shorter and simpler.
Cheers!

i think the answers of the foll SC's are:
1)180) Bluegrass musician Bill Monroe, whose repertory, views on musical collaboration, and vocal style were influential on generations of bluegrass artists, was also an inspiration to many musicians, that included Elvis Presley and Jerry Garcia, whose music differed significantly from his own.
(A) were influential on generations of bluegrass artists, was also an inspiration to many musicians, that included Elvis Presley and Jerry Garcia, whose music differed significantly from
(B) influenced generations of bluegrass artists, also inspired many musicians, including Elvis Presley and Jerry Garcia, whose music differed significantly from
(C) was influential to generations of bluegrass artists, was also inspirational to many musicians, that included Elvis Presley and Jerry Garcia, whose music was different significantly in comparison to
(D) was influential to generations of bluegrass artists, also inspired many musicians, who included Elvis Presley and Jerry Garcia, the music of whom differed significantly when compared to
(E) were an influence on generations of bluegrass artists, was also an inspiration to many musicians, including Elvis Presley and Jerry Garcia, whose music was significantly different from that of
Ans: B
Expln: just 'influenced' goes better than 'was influenced' and 'were influenced'
2) 193) Byron possessed powers of observation that would have made him a great anthropologist and that makes his letters as a group the rival of the best novels of the time.
(A) makes his letters as a group the rival of
(B) makes his letters as a group one to rival
(C) makes his letters a group rivaling
(D) make his letters as a group the rival of
(E) make his letters a group which is the rival of
Ans: E
Expln: It chould be make. hence The ans lies b/w d and e. E Sounds better. (tough which becomes a bit verbose)
