Final answer:
Ian can work the Coat Check and fill snack bowls, but likely cannot take alcoholic drink orders or open bottles of wine due to age restrictions on serving alcohol. Therefore, the correct option is a, b.
Step-by-step explanation:
The question asks which jobs a 16-year-old named Ian can perform at his aunt's restaurant. At the age of 16, Ian is legally allowed to work non-hazardous jobs. He can certainly work the Coat Check and be responsible for filling snack bowls as these tasks do not typically require handling alcohol or being exposed to potentially dangerous equipment or environments. However, taking alcoholic drink orders and opening bottles of wine may not be permissible under local laws, as most jurisdictions have age restrictions on serving alcohol, often requiring an individual to be at least 18 or 21 years old. Thus, while Ian can participate in many activities at the restaurant, tasks associated with serving alcohol are likely not among them.
