PROBLEM: Article: One of the tough things about being a high school student is that you never seem to get enough sleep at night, which often leaves you nodding off during classes. "The best amount of sleep to get is about seven and a half to eight hours," Peter Venn at Queen Victoria Hospital, UK, told The Telegraph. Spending either less than six or more than nine hours in sleeping puts your health at risk. A popular solution to a lack of sleep at night is to take a "power nap" during the day, but does this work? Generally speaking, it can be beneficial. Research shows that a nap in the middle of the day --even a brief one as short as five or 10 minutes ---can clear your mind and leave you with increased energy and improved productivity , according to Forbes. However, as refreshing as it might be, if you are getting adequate sleep at night, taking a power nap isn't such a wise choice. The reason is that sleeping during the day can interfere with your body's biorhythms . The brain gets used to going to bed at roughly the same time each night and getting up at the same time each day, and you don't want to disturb this routine. One more thing to keep in mind is that a power nap should never be used as a replacement for a good night's sleep. "Twenty minutes of power nap during the day is not like a tablet which will definitely work," Rahul Mukherjee, an Indian sleep specialist, told The Telegraph. "An hour's sleep before midnight is worth a couple of hours' sleep after midnight."
Answer: About seven and a half to eight hours.

SOLUTION: What is the healthiest amount of sleep for the majority of people according to the article?

PROBLEM: Article: One summer my friend and I decided to go to Italy for a holiday and we decided to travel there without going through a travel agency. You know, you would be submerged in crowds of tourists and lose lots of opportunities to get familiar with the country more closely. We started to think over our trip and managed to come up with a free tour of Italy. The trip was not very long but it was still very impressive. We look forward to going there again! Of course, we spent lots of time arranging the trip, but it was well worth it! Of course I was afraid that something would go wrong and I was especially anxious about my visa, but everything went quite smoothly in the end. ks5u The most difficult part was getting a visa without an invitation. In the Italian consulate , one must hand in some official paper proving that one has a hotel booked for oneself in order to get the visa. Then we had to solve the ticket problem. Airlines often sell cheap tickets and we bought ours far in advance. The next step was to book a hotel. We finally booked a hotel about thirty km away from the heart of Rome and it was the perfect choice for our trip. Every day we took a train that carried us to the heart of Rome. Our big house, which was surrounded by the forest, was a rare girl for the fresh air and silence, beautiful views, hospitable hosts, comfortable living conditions delighted us to no end. Besides this, we were very lucky that our mistress was Russian. She gave us a lot of advice that was of great use. She told us what transport to choose and where the best places to go. Don't be afraid to arrange your trip by yourself. It's not difficult! The only thing I'll say right now is that we really enjoyed traveling by ourselves. We walked with a map and a guide-book to wherever we wanted and we even met some of our fellow countrymen on the way just two or three times. So, if you're also planning a "single" trip, don't forget to take a Russian-Italian phrasebook as people in Italy prefer to speak in their native tongue.
Answer: He had a great time there.

SOLUTION: Why does the author want to go to Italy again?

PROBLEM: Article: At first all films were in black and white, but in 1932 the first color film was made. It proved as unpopular as making films had done in the late 1920's. It was not until 1938 that a full length color film was made, and the success of this film made producers everywhere change from black and white to color. This first full-length color film was translated into ten different languages and made Hollywood the main center( )of film industry In the early days of the cinema, other countries had also film industries. Very good films were made in Sweden, Britain, Russia and France. However, because Holleywood had so much money to spend, it kept its position as the world's most important film center.
