Article: While small may be beautiful, tall is just plain uncomfortable it seems, particularly when it comes to staying in hotels and eating in restaurants. The Tall Persons Club Great Britain (TPCGB), which was formed six months ago to campaign for the needs of the tall, has turned its attention to hotels and restaurants. Beds that are too small, shower heads that are too low, and restaurant tables with hardly any leg-room all make life difficult for those of above average height, it says. But it is not just the extra-tall whose needs are not being met. The average height of the population has been increasing yet the standard size of beds, doorways, and chairs has remained unchanged. "The bedding industry says a bed should be six inches larger than the person using it, so even a king-size bed at 6'6'' (6 feet and 6 inches) is falling short for 25% of men, while the standard 6'3'' bed caters for less than half of the male population." Said TPCGB president Phil Heinricy, "seven-foot beds would work fine." Similarly, restaurant tables can cause no end of problems. Small tables, which mean the long-legged have to sit a foot or so away from them, are enough to make tall customers go elsewhere. Some have already taken note, however. At Queens Moat Houses' Caledoman Hotel in Edinburgh, 6'6''beds are now put in as standard after requests for longer beds from taller visitors, particularly Americans. Question: What change has already been made in a hotel in Edinburgh? Yes or no, is the answer "6'6''beds have taken the place of 6'3''beds."?
No

Article: It took 100 years, but finally, scientists proved Albert Einstein's theory that gravitational waves exist. The waves were predicted as part of Einstein's general theory of relativity nearly 100 years ago. It was the theory of the physics behind the workings of our world and the universe. The idea was that the waves are like ripples in space, caused by some of the violent and energetic processes in the universe. For example, two black holes crashing into each other. Now a group of scientists, including ones from Caltech, MIT and the LIGO Scientific, Collaboration finally found the gravitational waves. David Reitze is the executive director of the LIGO observatory at Caltech. "We have detected gravitational waves. We did it!" What are these gravitational waves? Well, imagine throwing a rock into a pond. When the rock hits the flat surface of the water, it creates ripples or waves. Space-time is like the surface of the water. So that means gravitational waves are like the ripples moving out from where the rock hits the water. It might be hard to understand, but those gravitational waves expand and contract space and time as they move through space. And when they get to the Earth, the waves pass through, and they contract and expand the planet as the waves go by. It was Einstein who said these gravitational waves should be observable. But these are not huge waves. They are very, very small, which is why it took so long to find them. You cannot see them with your eyes. They are smaller than the size of an atom. How did the scientists find them? They used a giant scientific tool called LIGO, which stands for the Laser Interferometer Gravitational-Wave Observatory. The billion-dollar LIGO project is two L-shaped observatories. One is in Louisiana and the other in Washington state. For years, scientists have been watching two black holes in another faraway galaxy. The two were spinning around each other, moving closer and closer together. When they finally crashed into each other, it was with such power and force... Question: With the discovery of gravitational waves, we'll _ . Yes or no, is the answer "view the universe in a new way"?

Ques: Article: Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia. "Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.[: _ Z _ X _ X _ K] Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade. Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students' academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school. "At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills," according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters. "Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying." "Dating should not be considered a ceremony of growth in middle school," Orpinas concluded. Question: When doing his study, Orpinas _ . Yes or no, is the answer "found that the students' study skills have connection with their frequency of dating"?
Ans: No

Article: Here's an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What's more, you don't even need to touch the egg to get it to go in! For this experiment you will need: *a hard-boiled egg *a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well) *a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper *a match Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth. Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze through the mouth and into the bottle. As it entered the bottle, the egg may have broken into pieces. This happens when the diameter of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle's opening. Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts , and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle! Question: Why will the egg break into pieces while entering the bottle? Yes or no, is the answer "Because the diameter of the egg is too larger than that of the bottles opening."?
No
