In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.

Q: 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

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

Q: Article: Driving speeds have largely stabilized, and nowadays, safety concerns are important and reducing road accidents to minimum is a must. So, automakers are focused on safety systems more than ever before. Given the emphasis on improving safety, it's possible that well-known phrases such as "live fast and die young" may lose their meaning as innovative new devices are built into cars and trucks and other things that go. Many of the new safety systems that are being added to high-end vehicles are computer-assisted technologies that transfer some of the vehicle's operations to the vehicle itself, rather than relying only on the driver's decision-making skills. For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking when its built-in sensors detect a potential object ahead. The predictive brake assist basically places the vehicle's braking system on alert, which helps the system to slow down the car in as little time and as short a distance as possible. Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects based on simple patterns, such as other vehicles vs. a person. What's more, built-in "active systems", i.e., predictive precollision systems, will provide drivers with advance detection of potential contact between vehicles. These systems compute the movement of the objects and detect possible dangerous intersections . What technological developments have enabled innovations like predictive precollision systems? Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure communications. These communication links allow highways to provide a vehicle's owners with services such as renting a movie during the trip, as well as reduce reaction delays when medical care is needed due to a crash. Despite these new technologies, drivers cannot take safety for granted. Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the road and your hands on the steering wheel .
Answer: detect potential contacts between vehicles in advance

A: "Predictive Precollision" can be used to _ .

Q: Article: "We don't necessarily believe that new advertising, which might make consumers feel better about the Coke brand or better about the ads themselves , will actually result in consumers consuming more of the product," Morgan Stanley's Bill Pecoriello wrote in a research note the days after the investor meeting . But Coke is optimistic it can regain its old magic, and is banking on a new slogan: "Welcome to the Coke side of life." BREAK THROUGH HIT? With PepsiCo about to surpass Coke as the beverage king on Wall Street--Pepsi's market capitalization has _ in recent years to $97.9 billion, putting it less than a billion dollars behind its rival--the heat is on Coke . It's set to launch a new marketing campaign in March, 2006. And having taken a quick look at Coke's investor presentation on Dec. 7 in New York, my sense is that Coke may be moving in the right direction . Given the continued shift by consumers away from soda--Coke's stronghold --and into alternative beverages like juice, tea, and water, Coke badly needs a breakthrough hit. And given that shift away from soda, some analyists wonder whether even the catchiest new ads will be enough to put the fizz back into Coke. SAME OLD, UPDATED? The new flavors of PowerAde sports drink will probably enable Coke to continue stealing market share from PepsiCo's Gatorade brand. And Coke is getting a little more creative with packaging, including new, aluminum bottles of Coke that will be sold in nightclubs, and an 8.4-ounce "100 calorie" version of its flagship Coke that will appeal to women who want fewer calories and will like the fact that the small can will fit in their purse. I doubt whether other new products will be successful, including a new coffee-flavored soda called Coke-Cola Black that I tried. Think carbonated coffee. But I'm not sure if the product, which Coke is pitching as an afternoon pick-me-up for the 35-and-over set, is going to pull people away from their afternoon Frappucino fix. And my opinion is that Vault, an orange-flavored energy drink, will have just as much trouble unseating Mountain Dew among teens as did Coke's last attempt, a product called Surge. If there is one concern I have about the fresh offerings Coke plans to launch this year, it appears that many of them are simply new brands, not new products.
Answer: Nowadays Coke is comparatively less popular

A:
