The problem really lies in the stress that many of us experience. Stress robs you of the rest that you need by putting you in a state of pressure and worry. There are, of course, some methods that can help you relax, but only a few of them give you a good night's sleep. One of them is soothing music for sleep. Sleep music is not just for encouraging relaxation, it also can be used for various situations. Want to have a relaxing evening by yourself? Practice yoga in a comfortable environment? Think over something important? Then put on your favorite sleep music. Sleep music is not only fit for adults, but has also been known to be good for children. Soothing music helps your children go to sleep more easily. Massage therapists can also benefit from using soothing music for sleep in their clinics . This allows clients to benefit more from the session. For example, massage therapists can provide the relaxation of the body through their techniques, and the music helps clients relax their minds, helping them to relax deeper and feel more refreshed after the session. You'll never run out as there are some artists and companies that make sleep music. Choosing the right music is important as well. Like most music that you can find and buy in stores, sleep music has different styles, sounds, and subjects. There are those that are specifically for relaxation, while some are intended to help you go to sleep. The great thing about sleep music is that it will be something you'll be using for months, even years to come.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Robots have proved to be valuable tools for soldiers,surgeons and homeowners hoping to keep the carpet clean. But in each case,they are designed and built specifically for the job. Now there is a movement under way to build multipurpose machines-robots that can move about in changing environments such as offices or living rooms and work with their hands. All-purpose robots are not,of course,a new idea."It's been five or 10 years from happening for about 50 years,"says Eric Berger,co-director of the Personal Robotics Program at Willow Garage,a Silicon Valley organization. The delay is in part because even simple tasks require a huge set of capabilities. For a robot to fetch a mug,for example,it needs to make sense of data gathered by a variety of sensors-laser scanners identifying potential blocking objects,cameras searching for the target,force feedback in the fingers that grasp the mug,and more. Yet Berger and other experts are confident that real progress could be made in the next decade. The problem,according to Willow Garage,is the lack of a common platform for all that computational effort. Instead of enlarging the capabilities of a single machine,everyone is designing robots and the software to control them,from the ground up. To help change this,Willow Garage is currently producing 25 copies of its model PR2 (for"Personal Robot 2"),a two-armed,wheeled machine that can switch off the electricity,open doors and move through a room. Ten of the robots will stay in-house,but 10 more will go t o outside research groups,and everyone will share their advances. This way,Berger says,if you want to build the robotic equivalent of a Twitter ,you won't start by constructing a computer."You build the thing that's new." Options: A everyone is designing robots and the software to control them B they can produce 25 copies of its model PR2 C people can enlarge the capabilities of a single machine D people can start by constructing a computer Answer: A everyone is designing robots and the software to control them Question:
