Read the scenario carefully. After tapping "Done Reading", answer the deduction questions.
Emma is organizing a dinner party for her friends, inviting Alex, Ben, Charlie, David, and Emily. The event is set for Saturday at 7 PM. Alex follows a vegetarian diet, while Ben and Charlie enjoy meat. David has a shellfish allergy, and Emily adheres to a vegan lifestyle. To accommodate her guests, Emma plans to prepare two main courses: one featuring meat and another that is meat-free. Additionally, she will offer two side dishes: one that contains shellfish and another that does not. The shellfish-free side dish will also be vegan. Emma is aware that both Alex and Emily will avoid the shellfish dish. Through her discussions, she learns that Ben will consume the shellfish side dish, whereas Charlie will not opt for the vegan option. Consequently, Emma decides to serve a salad as the shellfish-free side dish, pairing it with the non-meat main course. The meat-based main course will be accompanied by the side dish that contains shellfish.
