Official Solution: The real estate baron Donald Trump presented a comprehensive introduction to advanced negotiations designed for graduate students in a two-year course. A. The real estate baron Donald Trump presented a comprehensive introduction to advanced negotiations designed for graduate students in a two-year course.
B. For graduate students, the real estate baron Donald Trump presented a two-year course, being a comprehensive introduction to advanced negotiations.
C. A comprehensive introduction was in a two-year course by the real estate baron Donald Trump presenting to graduate students an introduction to advanced negotiations
D. In a two-year course designed for graduate students, the real estate baron Donald Trump presented a comprehensive introduction to advanced negotiations.
E. Presenting a comprehensive introduction, the real estate baron Donald Trump introduced advanced negotiations in a two-year course designed for graduate students.
A. The original sentence suggests that Trump’s introduction covered
"negotiations designed for graduate students." This is nonsensical; rather the course is designed for graduate students and covers the general topic of negotiations.
B.. Beginning the sentence with
“for graduate students” is awkward and unclear. The verb phrase
“being a comprehensive introduction…” following the comma seems illogically to modify
“the real estate baron Donald Trump.” With the use of the unnecessary “being,” this creates the awkward suggestion that
“the real estate baron” was “a comprehensive introduction.” C. This choice makes the meaning unclear in its use of many prepositional phrases with no punctuation:
“In a two-year course” followed by
“by the real estate baron Donald Trump” and later,
“to graduate students” and “to advanced negotiations. Also, the subject of this passive sentence is
“a comprehensive introduction.” It would make more sense for Dona Trump to be the subject, since he was actively doing something: “presenting.” Finally, the use of "presenting" with the passive construction introduces a verb tense error; Trump is not currently "presenting" the course, rather, the course was presented by Trump.
D. CORRECT. The placement of the prepositional phrase
“in a two-year course designed for graduate students” at the beginning of the sentence clarifies the meaning: a negotiations course was designed for the students. The construction of the rest of the sentence is clear and concise.
E. The use of both “introduction” and “introduced” is redundant: it suggests that Trump
“introduced a comprehensive introduction.”Answer: D
