Answer

Brief Explanations:

Adding a salad - bar may cause more students to take time to select items, leading to longer lines for food. Lunch time is usually fixed and not directly shortened by adding a salad - bar. Costs may not necessarily increase if managed well, and adding a salad - bar doesn't inherently mean lower food quality.

Answer:

longer lines for food.
