Miguel is the head chef at a restaurant, Sofia is a line cook, and Eduardo is the sous-chef. Sofia reports directly to Eduardo, and Eduardo assists Miguel in managing the kitchen. Who is responsible for training Sofia, and can Eduardo make menu decisions without consulting Miguel? Respond very briefly.
Eduardo, as the sous-chef, is typically responsible for training and supervising the line cooks, which includes Sofia. In a kitchen hierarchy, the sous-chef serves as the second-in-command and is directly responsible for the kitchen's day-to-day operations under the head chef. Therefore, Eduardo would be entrusted with training Sofia.

Regarding menu decisions, while a sous-chef like Eduardo may contribute to menu development and suggest ideas, the ultimate responsibility and authority for menu decisions lie with Miguel, the head chef. The head chef sets the vision and creates the menu for the restaurant, while the sous-chef supports and executes that vision. So, Eduardo cannot make final menu decisions without the approval or consultation of Miguel, as the head chef is the decision-maker for such critical aspects of the restaurant's offerings.
