In Task-Based Language Learning (TBLL), 'a task' is best defined as:

What does the following task involve? 'Learners are given a hotel menu and they have to order food for four people for an amount of Rs. 1800. One is a vegetarian, and another is allergic to mushrooms. They have to keep Rs. 70 for an auto-rickshaw to go back to the hostel. Learners speak about what they will order, their preferences, and saving the money to get back.'
