Article: A trip across the Pacific will guarantee you a different experience with a tipping culture you've never come across in China. In the US, giving a little extra money to service workers on top of your bill is a common practice. Though US national law requires that businesses pay workers at least $7.25 (45 yuan) per hour, employees receiving tips--often waiters and waitresses--are the exceptions. They usually only receive at least $2.13 an hour, and tips make up the difference. As theWall Street Journalput it, "The American system of tipping holds the promise of great rewards for waiting staff." So how should you tip if you are in the US. Normally you pay tips as a percentage of the bill. Offering an extra 15 percent of the bill to the waiter or waitress in a restaurant and to the delivery man or woman is customary and expected. You can offer more for great service and less for poor service. Yet there is an exception. For take-out food, you don't have to provide tips, though some people say that filling an order still requires work and time that deserve a little extra--but maybe a little less. Tips are not expected at fast food restaurants, cafes or ice cream shops either, though a tip jar might be right by the cash register . Don't feel _ to throw some money in, but also remember that it doesn't hurt. Those workers do not rely on tips. Other service workers also receive tips. For taxi drivers, 15 percent is the norm , more if they help with your bags. Hairdressers often receive about 15 percent of the bill. The same goes for spa therapists and tour guides. Today, you can even pay tips on a credit card. When receiving a copy of the bill to sign, you are free to fill in how much you'd like to tip. Though thinking about when to tip and how much you should tip causes a big headache for many Chinese people, it's important to bear in mind that as long as you show respect and use your reasoning, things will be just fine.

input with options: Read the following article and answer the question. Article: Play allows children to use their creativity while developing their imagination and physical, cognitive , and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts. Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem. Children's development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children's vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children's world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children. Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional... Question: Compared with undirected play, play which is controlled by adults _ . Answer:
