Task: Question Answering
Input (English): Passage: When you work in a restaurant , after the customers have paid the bill and left , you have to clean up the table and prepare it for the next customer . Sometimes it can be very easy if it was only one person , but if it was a large family it could be very messy . All the left over plates , cups and utensils need to be cleared away to the kitchen to be washed . The table top will also need to be wiped down of any food or spills , so it is fresh and clean for the next diners . My favorite placemats are the ones you can color in , especially when they leave crayons on the table for you to use . Once the new place mats are down , a whole new table setting can be done . Often restaurants and cafes will have a special way they like their tables to be set up and its up to the wait staff to make sure that its done that way for every table . Some times it involves a whole new setting of plates , utensils and glasses and other times the table is bare except for the salt and pepper shakers . But regardless of what the restaurants table set up may look like , the table has to be ready so new customers can come in and enjoy their meal . Question: When do the placemats need to be replaced? Option1: After every diner. Option2: When customers arrive
Output (English): After every diner.
