Final answer:
Shaun's social status is 'controversial', as he is mentioned in both positive and negative extremes by his classmates but is typically not mentioned by most.
Step-by-step explanation:
Based on the information given in the question, Shaun's social status would best be described as controversial. This designation is used when a person has peers who have strongly opposing views about them, which is indicated by Shaun being listed on both the 'favorite person' and 'most disliked' lists by different classmates. Most students do not feel strongly about Shaun as he usually does not appear in either category, which further suggests that the opinions that do exist are polarized, making 'controversial' the appropriate label for Shaun's social status.
