In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: If you think by examining someone's facial expressions you can judge if he has good or bad luck in the stock market, think again. A study published in the journal, Science, has shown that body language provides a better signal in judging whether the observed subject has just gone through an intensely positive or negative experience. To test highly intense faces, Dr. Hillel Aviezer and his colleagues presented test groups with photos of dozens of highly intense facial expressions in real-life situations. In one study, they compared emotional expressions of professional tennis players winning or losing a point. To discover exactly how people view images, the researchers showed different editions of the pictures to three groups of participants: 1 ) the full picture with the face and body;2) the body with the face removed; 3) the face with the body removed. Remarkably, participants could easily pick the losers from winners when they judged by the full picture or the body alone, but they only had a 50:50 chance of being right when judging by the face alone. Strangely, the participants .who viewed the full image believed that it was the face, not the body, that revealed the person's emotions. In an additional study, the researchers performed the same series of tests, asking viewers to examine a wider range of real-life intense faces. Again, viewers were unable to tell faces in positive situations from negative situations. The researchers also "planted" faces on bodies expressing positive or negative emotions. Sure enough, the researchers discovered that the emotion of the same face on different bodies was determined by the body on which it appeared. "These results show that when emotions become extremely intense, the difference between positive and negative facial expressions no longer seems clear," says Aviezer. "The findings challenge classic behavioral models, in which the boundary between positive and negative emotions is clear." Aviezer adds, "The results may help researchers understand how body and facial expressions interact during emotional situations. For example, individuals with autism may fail to recognize facial expressions, but if trained to read important body language signs, their performance may significantly improve."
Answer: The participants were divided into three groups.
Example Output: What can we learn from the first study?

Example Input: Article: Nursing at Beth Israel Hospital produces the best patient care. If we are to solve the nursing shortage. hospital administration and doctors everywhere would do well to follow Beth Israel's example . At Beth Israel each patient is assigned to a primary nurse who visits at length with the patient and constructs a full-scale health account that covers everything from his medical history to his emotional state. Then she writes a care plan centered on the patient's illness but which also includes everything else that is necessary. The primary nurse stays with the patient through his hospitalization. keeping track with his progress and seeking further advice from his doctor. If a patient at Beth Israel is not responding to treatment. it is not uncommon for his nurse to propose another approach to his doctor. What the doctor at Beth Israel has in the primary nurse is a true colleague. Nursing at Beth Israel also involves a decentralized nursing administration; every unit is a self-contained organization. There are nurse-managers instead of head nurses; in addition to their medical duties they do all their own hiring and dismissing, employee advising, and they make salary recommendations. Each unit's nurses decide among themselves who will work what shifts and when. Beth Israel's nurse-in-chief ranks as an equal with other vice presidents of the hospital. She is also a member of the Medical Executive Committee. which in most hospitals includes only doctors.
Answer: The doctor gets more active professional support from the primary nurse.
Example Output: Which of the following best characterizes the main feature of the nursing system at Beth Israel Hospital?

Example Input: Article: Finally, the long-awaited flying car is almost here. AeroMobil, a Slovakian company, plans to start selling its creation, the AeroMobil3. 0, in 2017. The company claims on its site that the vehicle "transforms in seconds from an automobile to an airplane" by using "existing infrastructure created for automobiles and planes."The vehicle is petrol-powered and has wings that fold, which allows it to be parked like a car, though it is nearly 20 feet long. The company's website features a video where the AeroMobil 3. 0 drives out of a hangar ( )and goes down a highway, sharing the road with ordinary cars until it arrives at an airstrip. The car then unfolds its wings and takes off from a stretch of grass, rather than a paved tarmac , and flies through the air like any other small airplane. AeroMobil spokesman Stefan Vadocz said his company hasn't decided on an exact price because it's not ready yet."The prototype is a work in progress," he said in an email. But he said the price would be several hundreds of thousands of euros---somewhere in between a sports car and a light sports aircraft. The vehicle seats two people---the pilot and a passenger---and its single propeller is located at the rear of the plane. The company said the car's top speed on the road is at least 99 mph and while flying it is at least 124 mph. It can fly for 435 miles before running out of fuel. It has a steel framework and carbon coating and is powered by a Rotax 912, a four-cylinder aircraft engine from BRP of Austria. Flying cars aren't exactly new. The concept has been around since long before The Jetsons popularized the idea in the 1960s. It has been a regular topic in Popular Science ever since World War I ace, Eddie Rickenbacker, wrote about it in 1924. But getting a practical, reliable flying car off the ground has been a serious challenge. Glenn Curtiss discovered this in 1918 when he developed the Curtiss Autoplane. It turned out to be more of a hopper than a flyer, so it failed to become popular with the public.
Answer: Its petrol-powered engine and folding wings.
Example Output:
What allows the AeroMobil3. 0 to be parked as a car?
