In Manhattan GMAT (SC), Chapter 4, page 55
- "Jose's room is so messy that HIS mother calls HIM a pig" is incorrect
- "Jose's room is so messy that his mother calls Jose a pig" is correct
Because subject and object pronouns may NOT refer back to possessive nouns. Therefore the object pronoun "him" is used incorrectly because it may not refer back to Jose's.
In Problem Set, page 69, sentence number 15
- "Obstinate and surly, the manager's attitude prevented his staff from befriending him" is incorrect
- "The manager's obstinate and surly attitude prevented his staff from befriending him" is correct
why did we keep "him" in the first case, althought it had been replaced by the subject "Jose" in the second case?
