Which character was described as stuck-up and having a smug grin?

• A. Mattie
• B. Rooster Cogburn
• C. Columbus Potter
• D. LaBoeuf

Answer: (D)

The trait being tested is recognizing how a character’s demeanor is conveyed through their actions and expressions. LaBoeuf is the one described as stuck-up with a smug grin because he presents himself with polish, confidence, and a tendency to boast about his education and abilities. He carries himself with a refined, self-satisfied air and often wears a knowing, self-assured smile, signaling that he believes he’s superior or cleverer than others. This contrasts with Mattie Ross’s practical determination and Rooster Cogburn’s rough, unpolished grit, making LaBoeuf the character who fits the description of being stuck-up and having a smug grin. Columbus Potter doesn’t typically exhibit that same combination of refinement and smugness, so the fit isn’t as strong.
