Question: Article: A weather map is an important tool for geographers. A succession of three or four maps presents continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts to determine whether an individual pressure aroa is deepening or becoming shallow and whether a front is increasing or decreasing in intensity .They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a summary picture of conditions in the atmosphere at a given time. All students of geography should be able to interpret a weather map accurately.Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts and all climatic conditions in general. Twice a month it issues a 30-day"outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an anaiysis of the upper air levels which often set the stage for development of air masses, fronts and storms. Considerable effort is being exerted today to achieve more accurate weather predictions, with identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weathef modification studies.
Answer: frosts

Answer: One characteristic of weather maps NOT mentioned by the author in this passage is _ .

Question: Article: About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels on the ground rather than the roof. Then they began to develop the Solar Roadway. The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions, along with power and data delivery. They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being used to build and resurface current roads can be used to build the Solar Roadways. Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communications device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions _ need. According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots. The inventors say their Solar Roadway has many functions and advantages from main roads to driveways, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw $100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring .
Answer: costs no more money than current roads

Answer: In the inventors' opinion, the Solar Roadway _ .

Question: Article: On Sunday while I was having my own Father's Day celebration, I thought about my dad a lot. By the time I called to tell him that I loved him, he had already gone to bed. So I wrote the following to show what my dad means to me. About 28 years ago, my dad was a used car salesman. Every Thursday night, he would head off to Shreveport, LA for theauction . Most of the time, I drove a car over there for him so he could sell it there. One day, I was riding with my dad to Shreveport for the auction when he found ahitchhiker with a backpack. As soon as dad saw him, he pulled the car over and offered him a ride. Dad asked him his name and continued to talk to him about all sorts of things. I can't recall why but he told dad a lot of terrible things that had occurred to him. I sat in the back seat and watched the scene with amazement. I could see that the hitchhiker changed his attitude as he could tell someone who was really listening to him. We drove another forty-five minutes before we had to exit the interstate . We pulled over and dad told him to keep his head up and things would start looking up for him soon. He reached into his pocket and handed the hitchhiker a twenty-dollar bill and then a the-dollar bill. We drove on and my dad did not say a single thing. I was still completely amazed by what I just witnessed. I was always told everyone to never pick up a hitchhiker and yet my dad did it every single time he saw one. I'm sure that it made that poor man's day, probably a month to follow. While reflecting upon that story, I learned a lot about my dad and life. I learned that if you come from a place of service or compassion, you can change people's lives. Just one single kind act can change someone's life. It never occurred to my dad about not stopping to help him. This is the type of person my dad is. Thank you for setting such high standards for me to follow. Dad, I love you. Happy Father's Day!
Answer: on their way to Shreveport to sell a car
