1) indications should be followed immediately by "of sunspot cycles" rather than "on earth"

what is X,Y here? X is "Among the surest indications on Earth of sunspot cycles" and Y is "the rate at which trees grow" doesnt make sense,should be other way around

do you think that "as seen in the rings visible in the cross sections of their trunks" correctly modifies sunspot cycles?

If it did then the pronoun their would refer to sunspot cycles. As far as I know sunspot cycles don't have trunks ...

Could you elaborate please

Rate - is and not are (try inverting the sentence)

D - Run on sentence

So E it is

WHAT IS BEING TESTED HERE: SUBJECT VERB AGREEMENT + PRONOUN + STRUCTURE + SPECIAL ATTENTION NEEDS TO BE GIVEN TO ANY PRONOUN BEFORE OR AFTER THE UNDERLINED SENTENCE..."THEIR" IN THE LATER PART OF THE SENTENCE..WITHOUT AMBIGUITY "THEIR" SOULD REFER TO TREES.LETS LOOK AT THE OPTIONS ONE BY ONE

A. On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow
"RATE" SUGGESTS THAT WE NEED A SINGULAR VERB "IS"
"THEIR" CORRECTLY REFERS TO TREES
"RATE THAT" IS INCORRECT USAGE "RATE AT" IS CORRECT...OUT
B. On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth
"RATE" SUGGESTS THAT WE NEED A SINGULAR VERB "IS"..
"TREE GROWTH AS SEEN" IS INCORRECT FORM...OUT
C. On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles
THE FIRST PART OF THE SENTENCE IS PERFECTLY CORRECT BUT THE PLACEMENT OF
SUNSPOT CYCLES SEEMS TO MODIFY "THEIR" IN THE LAST HALF OF THE SENTENCE MAKING THIS SENTENCE A TRAP.....OUT
D. Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate
"IS" VERB NEEDED IN PLACE OF COMMA BETWEEN "CYCLES" AND "BELIEVED"
"INDICATIONS ON" IS SUSPECT.."INDICATIONS OF" IS FAR BATTER AND SAFER
"TREE GROWTH RATE" IS AN AMBIGUOUS PHRASE..
"AMONG THE X..."IS" Y" MAKES A COMPLETE SENSIBLE SENTENCE..THIS OPTION LACKS THE PRIMARY VERB "IS".TAKE A CLOSER LOOK....OUT
E. Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow
"INDICATIONS ON" IS SUSPECT BUT LETS LOOK AHEAD
"IS" IS CORRECT VERB "IS BELIEVED T BE" IS CORRECT USAGE
"RATE AT WHICH TREES GROW" IS ALSO CORRECT
"THER" MODIFIES TREES WHICH IS CORRECT
SO....E SOUNDS THE BEST OF THE LOT..
C HAS A MAJOR FLAW WITH THE PRONOUN REFERRANT OR ELSE C WOULD HAVE BEEN A BETTER CHOICE THAN E

So OA is C.

C. the rate at which trees grow is believed to be among the surest indications of sunspot cycles, as seen in the rings visible in the cross sections of their trunks.

But I agree with sasen. Sunspot cycles do not have trunks. "Their" incorrectly refers to sunspot cycles.

E is not flawless, as it is awkwardly constructed. But it still is the best answer.

Another poor question in the Brutal SC document. I would like to know its source. It was not taken from SC 1000.

"On Earth" in the begining of A,B,C possibly means that one some ther planet there cab be some other indications which is not the intent hence wrong.
D is also incorrect as "believed to" is referring to sunspot cycles.
E is correct answer.

I think we are assumig something which is not mentioned in the sentence...and IMO GMAT tests grammatical correctess..pls correct me if i m wrong..
If we only focus on grammitcal aspect of sentence then C is the appropriate option to select.

the ans has to be C.. we are wrongly introducing a false alarm of other planets..
as far as E is concerned, pl read the statement clearly it says 'among the surest.... is believed to be the rate at ....."............. this is not the correct way it should be ' the rate at .... is believed to be among the .....' the two sentences mean different

For the reasons mentioned by Manhattan's staff I picked E.
Sure, it is an inverted construction. But the meaning indicates that only the signs on earth are part of investigation. C excludes "earth" completely. That's why E is a better choice.

Guys, besides answering this question, could you also comment on what is "as seen in the rings visible in the cross sections of their trunks" referring to? seen what?


IMO C --- short, active and concise .... confusion over
