Her boss had ordered _____ to think up a new slogan for a very important client.

• A. Him
• B. Her
• C. They
• D. Us

Answer: (B)

This tests choosing the right object pronoun after verbs like order. After “ordered” we need an object pronoun for the person who is being told to do something. Since the sentence starts with “Her boss,” the person performing the action is the woman who has a boss. The appropriate object pronoun for a female singular referent is “her.” So, “Her boss had ordered her to think up a new slogan for a very important client.” Using “him” would imply a male, “they” is not the correct object form here (and would require “them” if plural), and “us” would imply the speaker is included.
