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
Can anyone tell why C is rt ? IMO : D should be correct looking at options available
Hey
awichalObserve the below part from the prompt -
but their chemical composition is different than any terrestrial lavaIn this part we know their refers to Tektites and the meaning of this part becomes -
Chemical composition of Tektites is different than chemical composition of any terrestrial lava.
Now to convey this idea grammatically, we require the noun [chemical composition] itself or we can use the pronoun [that] as the next best option.
While going through the options, we observe that only C and E have this structure that keeps the meaning as intended.
E can be rejected because of the possessive form of
terrestrial lava's.
This can be re-written as [that of any terrestrial lava's] ------> [chemical composition of any terrestrial lava chemical composition]
and this does not make any sense.
Hence Option C is our correct answer.
Hoping this to be helpful !!!
