Acid rain is the phenomenon
responsible for the deterioration of many marble monuments and causes primarily by the reaction of emissions containing carbon and sulfur with water molecules.
A) responsible for the deterioration of many marble monuments and
causes B) that is responsible for the deterioration of many marble monuments and that
causes C)
that is responsible for the deterioration of many marble monuments, which is caused
D) responsible for the deterioration of many marble monuments and is caused
E) that is responsible for the deterioration of many marble monuments, and which
causes Meaning: Acid rain:(1)
is the cause
of deterioration of marble monuments and
(2) is
caused mainly
by a reaction between polluted air and water molecules.
Split #1: Verb error - CAUSES BY is incorrectWhether the subject of the second verb (cause) is acid rain or deterioration,
"causes by" in both constructions is incorrect.
WRONG: acid rain
causes by the reaction of X and Y or
WRONG: deterioration
causes by the reaction of X and Y
The reaction between emissions and water is the cause; acid rain or deterioration of marble monuments is the result.
Either way, the construction should be X (acid rain or deterioration) is caused by Y (a reaction between polluted and and water)
Eliminate Options A, B, and E
Split #2: meaning and an unnecessary "that is"Option C means: Acid rain is the X that is primarily responsible for deterioration, which [deterioration] is caused by a bad reaction between Y and Z.
Option D means: Acid rain is primarily responsible for deterioration and is caused by a bad reaction between Y and Z.
Although the question may purport to test parallelism,
unless we assume from the outset that "that is" is unnecessary,
parallelism is not all that obvious.
In this case, option D is simply better than C.
1) D does not contain "that is," and does contain a parallel structure.
Acid rain IS primarily responsible for deterioration of marble and IS caused by a reaction between air pollution and water particles.This sentence correctly punctuates a single subject with a compound predicate (two verbs).
The correction punctuation is AND (no comma)
2) C includes "that is," which is probably not necessary.
Further, although it is logically possible that deterioration is caused by the reaction
between emission particulates and water molecules, that causal chain is not direct.
Deterioration is caused by acid rain.
rain (acid rain) comes from water molecules.
Deterioration does not "come from" water molecules.
Option D makes more sense. Eliminate C
Answer D
