Example Input: Article: The Channel is the name given to the stretch of water which separates England and France. Ferries operate all year round to carry people across the Channel, and they are busy most of the year. January is the only quiet month nowadays. As well as summer holiday-makers, there are day trippers and coach traffic, not to mention lorries and other commercial vehicles. Some ferries carry cars and their passengers, while others also connect train passengers with the Continental rail network. The biggest hazard for the ferry is the wind. The crew listens to BBC weather reports four times a day. Or they sometimes get gale warnings from local radio station. Crossing the Channel by ferry is a bit like trying to cross Oxford Street on a busy afternoon, according to one ferryboat captain. The ferries from Folkstone and Dover to Calais and Boulogne have to cross the main flow of traffic. This consists of ships traveling through the Channel to and from Northern Europe. There may be four hundred ships making the journey at any one time, and they all pass through a "choke point" which is only fifteen miles (twenty-five kilometers) wide. The cross-channel ferries have to sail right through the middle of all this traffic.
Answer: what crossing the Channel by ferry is like
Example Output: The passage is mainly concerned with _ .

Example Input: Article: Australian sleep researchers have developed a set of hi-tech "sunglasses", described as the world's first "time control" glasses, which can imitate sunlight patterns. The team, from Flinders University, in Adelaide, says the glasses send out a soft green glow that helps a traveller adapt to changing sleep patterns and time zones in "small steps". It targets a part of the brain that regulates the human body-clock, by sending signals to the rest of the body that help it slowly realise it is in a different area of the world. It has been suggested the device, called the "Re-Timer", is currently the only wearable body clock adjustment system commercially available. Scientists say the device, officially launched in South Australia, can help ridf the negative effects of long-timel travel and bring new relief to insomnia sufferers, shift workers and even teenagers. "The light from Re-Timer stimulates the part of the brain responsible for regulating the 24-hour body clock," said Prof Leon Lack, its chief inventor. Extensive research has shown that green light is one of the most effective wavelengths for influencing the body clock. The battery-powered device, which retail for PS162 in Britain, then sends signals that cause the production of hormones and daily cycles known as circadian rhythms . Those people who want to sleep peacefully, but wake earlier, should wear it for 50 minutes in the morning for three days. Those who want a lie- in, should wear it for the same time before bed to delay the body clock. The device, which is powered by an inbuilt rechargeable battery, can also be worn as sunglasses during daily tasks such as reading or using a computer. "The glasses have been designed to be user friendly and comfortable to wear so people can go about their normal activities wearing them at work or at home," he said, adding they had been designed based on 25 years of university research. It is estimated that up to 94 per cent of long-time travellers suffer from jet lag because the body becomes confused to travelling through different time zones. So the glasses are good news to them. It uses the outside world as indicators as to whether it should be awake or asleep including factors such as light, silence or noise. Airlines are said to be seeking a "silver bullet" for the tiredness and confusion that often follow a long-timel flight and are in discussions to buy the device.
Answer: motivating part of the brain
Example Output: The "time control" glasses work by _ .

Example Input: Article: Gwendolyn Brooks wrote hundreds of poems during her lifetime. She was known around the world for using poetry to increase understanding of black culture in America. During the 1940's and the 1950's, Gwendolyn Brooks used her poems to describe conditions among the poor,racial inequality and drug use in the black community.

The Bronzeville poems were her first published collection. In 1950, Gwendolyn Brooks became the first African American to win the Pulitzer Prize for Literature. She won the prize for her second book of poems called "Annie Allen". "Annie Allen" is a collection of poetry about a Bronzeville girl as a daughter, a wife and a mother. She experiences loneliness, loss, death andpoverty . Gwendolyn Brooks said that winning the prize changed her life. Her next work was a novel written in 1953 called "Maud Martha". "Maud Martha" attracted little attention when it was first published. But now it is considered an important work by some critics. Its main ideas about the difficult lives of many women are popular among female writers today.
