Taken from the Barron's SAT prep book:
- "Ron liked to play word games, of which he found crossword puzzles particularly satisfying."
According to the answers this is an unidiomatic phrase that is too wordy and they fix it by adding a semi-colon and making the second clause into an independent one:
- "Ron liked to play word games; he found crossword puzzles particularly satisfying."
My question: how is and which part of the first sentence unidiomatic, and how is it better than the second one?
In the first sentence the "of which" conveys the idea that the second clause is a part of the first, as opposed to the second sentence in which the semi-colon only expresses a connection between the two clauses.
Here's the exact copy of the question for those who are interested:
