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.

Example Input: 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
Example Output: "Predictive Precollision" can be used to _ .

Example Input: Article: A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as "greenhouse gases". And the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us. The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth's temperature of between I and 4degC;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
Answer: a natural course that is to a certain degree useful to us
Example Output: According to the passage, we can know "greenhouse effect" means _ .

Example Input: Article: When you think of photographing people, you may think of your family reunion or the Christmas party at work. These types of pictures of people are records of fun events with nice memories. Let's take a look at another idea for taking pictures of people, with an entirely different slant. Much as anthropologists study the diversity of characteristics of people in cultural and environmental contexts, some photographers record these aspects of people in their pictures. They try to capture the emotions and humanity of people, and the photograph draws the viewer into the subject's experience at that moment in time. Taking pictures of people with this goal in mind makes the photographer and the viewer grow in the understanding of human nature. For example, a photograph of a young man trying to hitch a ride in the rain can show the experience. His poncho sparkles with the raindrops flowing in a steady stream to the ground. The lights of passing traffic highlight the contrast between the warm, dry drivers, taking no notice of his misery. Another picture of a child sleeping on a bench at a busy train station can capture the innocence of childhood contrasted with a busy world of hurried grown-ups. If you'd like to experiment with this form of photographs of people, look for ordinary people in contrasting environments or contexts. Children and the elderly pose extraordinary possibilities. The lined faces of the aged often make great subjects, reflecting character and wisdom. People are such interesting subjects. Facial expressions can convey a thousand moods and feelings. Taking pictures of people with an eye to the feel and magic of the moment will make you a better and more enthusiastic photographer. You may find yourself so taken with this new experience. Photographing people is an artful endeavor. Take the leap!
Answer: know better about human nature
Example Output:
According to the passage, a picture that shows the emotions and humanity of people may help you _ .
