Official Solution:
A controversial study suggests that the violent behavior displayed by some teenagers who play several hours of video games a day is because of developmental damage that is caused to the frontal lobe region of the brain rather than the absorption of any specifically violent content.
A. because of developmental damage that is caused to the frontal lobe region of the brain rather than
B. caused due to damage in development of the frontal lobe region of the brain instead of
C. because the frontal lobe region of the brain is damaged during development rather than
D. because of damage caused during development of the brain’s frontal lobe region instead of
E. due to developmental damage to the frontal lobe region of the brain rather than
The distinction between “because of” and “due to” is tested. Although both are used to depict an effect, “due to” is used when the effect is a noun, whereas “because of” is used when the effect is a verb.
The game was delayed
because of the rain. (verb + because of)
The delay was
due to the rain (noun + due to)
In the question the effect is a noun (“behavior”). Therefore “due to'' must be used.
A. “Because of” is wrong - “due to” must be used when the effect is a noun.
The part “damage that is caused to the frontal lobe region” is unnecessarily wordy - “damage to the frontal lobe” is more concise and hence better.
B. “Caused” and “due to” are redundant. Moreover, grammatically the construction changes the effect to a verb (“caused”), and hence “due to” cannot be used. “Damage in development” distorts the meaning. The damage is in the frontal lobe region, not in the development.
C. Wrong parallelism in “X rather than Y”: X = “the frontal lobe region of the brain is damaged during development”, a clause, but Y = “the absorption of any specifically violent content”, a noun phrase.
D. “Because of” is wrong - “due to” must be used when the effect is a noun.
Meaning is distorted - it is not clear that the damage is caused to the frontal lobe region.
E. CORRECT. “Due to” is correctly used. In the idiom “X rather Y”, X = “damage”, a noun and Y = “absorption”, also a noun - hence parallelism is maintained. The part “developmental damage to the frontal lobe region” is concise.
