I have some questions about the Problem Set of Chapter#4 of Sentence Correct Strategy Guide : MGMAT.
1. Other than what is given in the solution for these problems are these variations also correct:
Q3. Ravaged by civil war....Portugal, Angola, which is now ....stories, has an economy that grew by 21% last year, and its parliamentary elections ....week.
Q9. James was unaccustomed to the rigors of college life, so his grades dropped?
2.In solution of question 5, why relative pronoun "where" is not used after all Bordeaux is a place, wouldn't that be more appropriate than using "whose".
So is my variation correct? Well informed people know that Bordeaux is a French region, where most famous export is the wine that bears its name?
