Tektites, which may have been propelled to Earth from lunar volcanoes, are much like the volcanic glass obsidian, but their chemical composition is different than any terrestrial lava; they contain far less water than obsidian does and none of its characteristic microcrystals.

(A) is different than any terrestrial lava; they contain
(B) is different than any terrestrial lava's, containing
(C) is different from that of any terrestrial lava; they contain
(D) differs from any terrestrial lava in containing
(E) differs from that of any terrestrial lava's, containing

SCIENTIFIC AMERICAN
August 1978
Volume 239, Issue 2

In widely scattered locations around the world small glassy pebbles of curious surface configuration and distinctive composition are found, often in vast "strewn fields" that stretch across land masses and, on the evidence of cores drilled from the deep-sea floor. across intervening seas and oceans. These tektites. as they are called from the Greek word tektos, meaning molten, are much like the volcanic glass obsidian, but their chemical composition is different from that of any terrestrial lava and they contain far less water and none of obsidian's characteristic microcrystals. And, as the Austrian mineralogist Josef Mayer pointed out in 1787, no one has ever found the Mutterstein. or mother lode, of a field of tektites. They cannot, therefore. be the product of terrestrial volcanism.

C)...the right idiom is "different from". A) and B) are out. D) is out because it compares chemical composition to the lava. E) is out because it is not clear if "containing" refers to "lava" or to "composition".

(A) is different than any terrestrial lava; they contain
(B) is different than any terrestrial lava’s, containing

I think C is flawed too ..."They" looks suspicious....I would go with D

It is (C) for Parallelism.

(D): "in containing far less water than obsidian does .." : wrong : "does" does not have any verb to refer.

OA is "C"


A, B eliminated because of "different from".....

D bad comparison.

Both C and E seen right.

I chose C. But i aint sure what is wrong with E.

IC = Tektites, which may have been propelled to Earth from lunar volcanoes, are much like the volcanic glass obsidian, but their chemical composition differs from that of any terrestrial lava’s

Phrase [Participle modifying Subject Teckites] = containing far less water than obsidian does and none of its characteristic microcrystals.

IC, Phrase

Any explain what is wrong with E???

E says as if the chemical composition contains far less water-------

but it is tektites, which contains far less water-----.

thats why E is wrong and C correct.

To me here is what E says:

Tektites, which may have been propelled to Earth from lunar volcanoes, are much like the volcanic glass obsidian, but their chemical composition differs from that of any terrestrial lava’s, containing far less water than obsidian does and none of its characteristic microcrystals.

the phrase in green is an absolute phrase modifying the subject Tektities. Absolute phrases dont have to modify the noun right next to it. It could modify a) a subject of the previous clause b) object of a previous clause or c) the entire clause.

Any solid explanations why?

gmataquaguy,

"their chemical composition differs from that of any terrestrial lava’s, containing far less water than obsidian does and none of its characteristic microcrystals". --- this is a independent clause joined to another independent clause with the help of a coordinating conjunction "but".

the other I.clause is " Tektites, which may have been propelled to Earth from lunar volcanoes, are much like the volcanic glass obsidian"

again the possesive form (lava's) is wrong.

E compares "chemical composition of tektitis" with "chemical composition of lava's containing far less water----" isn't it wrong.

I dont agree with your comparison. Here is why:

Here is what the IC after but says in E.

their [Tekkites] chemical composition differs from that of any terrestrial lava’s.
Step1:
The possessive form of lava is correct because enables comparison between Teckites's chemical composition and lava's.

This statement is analogous to

My car is faster than Jane's ----> Here Jane's = Jane's care [implicit].

Step2:

IC, containing far less water than obsidian does and none of its characteristic microcrystals.

I'm saying that "containing....." isnt a participle phrase. Its an absolute phrase that modifies the subject teckites.

Please read absolute phrases from [http://webster.commnet.edu/grammar/phrases.htm#participial] and http://www.gmatclub.com/phpbb/viewtopic.php?t=1540

and you will see why i'm asking these questions.

either you have the "possesive form" or you use the construction "that of", but not both.

taking your example-

My car is faster than Jane's ----> - CORRECT

My car is faster than that of Jane ----> - CORRECT

My car is faster than that of Jane's ----> INCORRECT

Yes, that's exactly the reason I would choose C over E.
