I'm taking a test and have to guess the right answer to the question after the article. Article: Global Positioning Systems   are now a part of everyday driving in many countries.These satellitebased systems provide turnbyturn directions to help people get to where they want to go.However,they can also cause a lot of problems,send you to the wrong place or leave you completely lost.Many times,the driver is to blame.Sometimes a GPS error is responsible.Most often,says Barry Brown,it is a combination of the two. Barry Brown is with the Mobile Life Centre in Stockholm,Sweden.He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPSequipped car to use during his stay.Mr Brown says,"They just plugged in an address and then set off to their destination.And,then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address in.So again,the GPS is kind of 'garbage in garbage out'." Mr Brown says this is a common human error,but what makes the problem worse has to do with some of the shortcomings,or failures,of GPS equipment.He says,"One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn,sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." Mr Brown says,"One of the things that struck us,perhaps the most important thing was that you have to know what you're doing when you use a GPS.There are these new skills that people have developed.There are these new competencies   that you need to have to be able to use a GPS because they sometimes go wrong.This goes against a common belief that GPS systems are for passive drivers who lack navigational skills." Barry Brown says to make GPS systems better we need a better understanding of how drivers,passengers and GPS systems work together. Question: What's the main idea of the text? Options: A: GPS systems are helpful for drivers. B: Driving with GPS can be difficult to navigate  . C: Drivers should understand how GPS systems work. D: Drivers should learn to use GPS systems correctly.

I'm taking a test and have to guess the right answer to the question after the article. Article: About half American teenagers do not get enough sleep on school nights.They get an average of sixty to ninety minutes less than experts say they need. One reason for _ is biology.Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups.Yet many schools start classes as early as seven in the morning.As a result,many students go to class feeling like sixteenyearold Danny.He is an active teen-- except in the morning."Getting up in the morning is pretty terrible.I'm just very out of it and tired.Through the first and second period I can hardly stay awake," he said. Michael Breus is a psychologist.Teens,he says,need to sleep eight to nine hours or even nine to ten hours a night.He says sleepy teens can experience a form of depression  that could have big influence on their general well being.It can affect not just their ability in the classroom but also on the sports field and on the road.So what can schools do about sleepy students?The psychologist says one thing they can do is to start classes later in the morning.Studies show that students can improve by a full letter grade in their first and second period classes. Eric Peterson is the head of St.George's School in the northeastern state of Rhode Island.He wanted to see if a thirtyminute delay would make a difference.It did.He says visits to the health center by tired students decreased by half.Late arrivals to the first period fell by a third.And students reported that they were less sleepy during the day.Eric Peterson knows that changing start times is easier at a small school like his.But he is hopeful that other schools will find a way. Question: Michael Breus thinks that  _  . Options: A: teens should get up early B: teens need enough sleep to be lively C: depression is common in teens D: the first period class should be cut off
