[Q]: Article: Great British is an island that lies off the northwest coast of Europe. The nearest country is France which is 20 miles away. Great British is separated from France by the English Channel. The island is surrounded by the Atlantic Ocean, to the west, and the North Sea, to the east. It includes the main lands of England, Wales and Scotland. Scotland is in the north while Wales is in the west. Ireland, which is also an island, lies off the west coast of Great Britain. It is made up of Northern Ireland and the Irish Republic. Great Britain together with Northern Ireland forms the United Kingdom (U.K.). So the U.K. is made up of four countries. The largest of these is England which is divided into 43 countries. The capital city is London which is on the river Thames.
Question: Great Britain is separated from France by _ .
Options: (A) the North Sea (B) Suez Canal (C) English Channel (D) Thames

[Q]: Article: I was on vacation, and in my mind, vacation does not mean setting my hotel room alarm clock for 6 am. But when you're in Aruba and hoping to reserve a beachside palapa , that's exactly what you do. Tourists begin lining up at the crack of dawn to secure these umbrella-like wood structures that are covered with dried and woven palm leaves. They then place towels on chairs and call them theirs for the day, whether they remain there or not. I knew nothing of _ on my first day in Aruba. I saw an empty chair covered with a towel and took it. It was a big mistake. For many visitors, a week bathing in the sun is the only activity they wish to pursue. It sounded good to my girlfriend, Barbara, and me after Boston's awful winter. Six more inches of snow was predicted on the day we left. The sun, the sand, and the beach seemed just about right. Aruba's slogan is "One Happy Island", and it doesn't take long to understand why. Aruba is said to be on "island time". Translation: No one is in a rush to do anything. When in Aruba, you go with the flow, however slow and lazy that might be. Cooling trade winds, white sandy beaches, turquoise waters, and dazzling sunsets are all good reasons to visit. But this 20-mile island offers more than lazy days walking on the beach. There is amazing night life, casinos, golf, scuba diving , fine dining, shopping, and a great national park. But our first day was spent as you'd expect, swimming in the sea and enjoying cool drinks. Our drink of choice quickly became the Coco Loco. It's as refreshing as it sounds.
Question: Tourists get up at 6 am because they _ .
Options: (A) want to see the sunrise early (B) need to check out early (C) want to have fun longer (D) need to reserve a beachside palapa

[Q]: Article: As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free - form gestures - sweeping fingers in shapes across the screen of a smart phone--can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords. "All that it takes to steal a password is a quick eye," said one of the researchers of the study. "With all the personal information we have on our phones today, improving their security is becoming increasingly necessary." In developing a secure solution to this problem, the researchers studied the practicality of using free - form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity. The researchers carried out a create - test - retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free - form gestures as passwords. To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens , attempt to steal a free - form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks. Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free - form passwords in the future. They believe this is the first study to explore free - form gestures as passwords. They will soon publish their findings.
Question: What can we learn about free - form gestures?
Options: (A) They are improving mobile security in a way. (B) Users will have to make use of simple gestures. (C) They will never be copied by others. (D) Users must move their fingers in fixed shapes.
