Final answer:
Sal thinks it is remarkable that Mrs. Partridge correctly guesses Phoebe's age B) because Phoebe looks older than her actual age.
Step-by-step explanation:
The correct option is B) Because Phoebe looks older than her actual age.
In the given quote, it is mentioned that Mrs. Partridge correctly guesses Phoebe's age, and Jane finds it embarrassing to meet the child's gaze. This suggests that Phoebe's age is not what one would expect based on her appearance.
When someone looks older than their actual age, it can be remarkable or surprising to others. In this case, it seems like Sal also finds it remarkable that Mrs. Partridge was able to accurately guess Phoebe's age because it goes against the assumption someone might make based on her appearance.
By choosing option B, we acknowledge that Phoebe's appearance is a factor in why Sal finds it remarkable that Mrs. Partridge was able to correctly guess her age.
