Entomologists have recently discovered what appears to be a global mega-colony of ants, a massive complex that consists of over 22 million interconnected anthill networks constructed by over 200 billion Argentinean ants some 100 years ago and
sprawling across the Americas, Europe, Australia, and Asia.
(A) sprawling
(B) sprawls
(C) sprawled
(D) it sprawled
(E) is sprawling
(A) sprawling
The question is of parallelism. And both the side of the conjunction
"and" should be parallel. The common element(or multiplier) is
"a massive complex that". Since there is verb on left side of the "and" there should also be a verb on the right side for the parallelism to hold. Any verb-ing only acts as a verb when it has a form of "be" before it. In this option
sprawling acts as a noun. Thus it can be eliminated.
(B) sprawls.
This option
helps in maintaining parallelism. It also
conveys the intended meaning of the sentence correctly. By using the present tense "sprawls", the fact the massive complex sprawls across 4 continents. Looks promising. Lets keep it.
(C) sprawled
It does help in maintaining the parallelism but
distorts the meaning by suggesting that the complex no longer sprawls across various continents. Thus we can eliminate it.
(D) it sprawled
The
use of "it" is not correct and the meaning of the sentence is distorted by suggesting that the complex no longer sprawls across various continents. Thus we can eliminate it.
(E) is sprawling
It does help in maintaining the parallelism but distorts the meaning by suggesting that the complex at the
very present is sprawling.We only want to convey a fact. Which can be done by using a present tense "sprawls". Thus we can eliminate it.
Therefore the correct answer is option B
