Verb Forms + Meaning + Modifiers Understanding the intended meaning is key to solving this question; the intended meaning of this sentence is that electroconvulsive therapy is a longstanding method for treating a variety of psychiatric disorders by passing 800 milliamperes of electricity through the brain and is now administered sparingly because it engenders considerable controversy.
• Information that is permanent in nature is best conveyed through the simple present tense.
• “who/whose/whom/which/where”, when preceded by a comma, refer to the noun just before the comma.
A. Trap. This answer choice incorrectly modifies “psychiatric disorders” with “involving the passing of 800 milliamperes…”, illogically implying that electroconvulsive therapy is a longstanding method to treat those psychiatric disorders that involve the passing of 800 milliamperes of electricity through the brain; the intended meaning is that electroconvulsive therapy is a longstanding method to treat psychiatric disorders through the passing of 800 milliamperes of electricity
through the brain.
B. Correct. This answer choice correctly modifies “Electroconvulsive therapy” with “involves the passing of 800 milliamperes … and is now administered sparingly”, conveying the intended meaning of the sentence- that electroconvulsive therapy is a longstanding method for treating a variety of psychiatric disorders by passing 800 milliamperes of electricity through the brain and is now administered sparingly because it engenders considerable controversy. Further, Option B correctly uses the simple present tense verb “engenders” to convey information that is permanent in nature.
C. This answer choice incorrectly modifies “psychiatric disorders” with “involving the passing of 800 milliamperes…”, incorrectly implying that electroconvulsive therapy is a longstanding method to treat those psychiatric disorders that involve the passing of 800 milliamperes of electricity through the brain; the intended meaning is that electroconvulsive therapy is a longstanding method to treat psychiatric disorders
through the passing of 800 milliamperes of electricity through the brain. Further, Option C incorrectly uses the present participle (“verb+ing” – “endangering” in this sentence) construction “because of engendering” to convey information that is permanent in nature; please remember, information that is permanent in nature is best conveyed through the simple present tense.
D. This answer choice incorrectly modifies “psychiatric disorders” with “that involves the passing of 800 milliamperes…”, illogically implying that electroconvulsive therapy is a longstanding method to treat those psychiatric disorders that involve the passing of 800 milliamperes of electricity through the brain; the intended meaning is that electroconvulsive therapy is a longstanding method to treat psychiatric disorders
through the passing of 800 milliamperes of electricity through the brain.
