PROBLEM: Article: Ocean Park If you love the sea, Ocean Park is the place for you! Situated on the south side of Hong Kong Island, this 870,000 square metre educational theme park provides many opportunities to learn about marine life. To start with, the park boasts the Atoll Reef, one of the world's largest aquariums, with about 2,500 fish from nearly 300 different species. What makes this aquarium special, however, is not just its size, but also its design. The Atoll Reef is built with an observation passageway that circles the aquarium on four different levels. This lets visitors view sea life from a variety of depths and angles. Then there's the Shark Aquarium, a tank with more than 200 sharks from more than 30 species. Like the Atoll Reef, this unique aquarium is designed to make sure guests get the most out of their visit. Shaped like an underwater tunnel, guests can watch as sharks swim overhead and dive at them from every side. There's also the Sea Jelly Spectacular, an aquarium that houses more than 1,000 jellyfish of all shapes, colours and sizes. And at the park's Dolphin University, visitors can go on educational tours and watch the training of dolphins up close. The park's most popular attraction is the Ocean Theatre, a huge outdoor pool where dolphins and sea lions entertain the visitors. Sometimes a killer whale even takes part in the performance! Although Ocean Parks focus is on the water, the theme park has plenty of other activities, too. For people seeking excitement, there are rides like the Abyss Turbo Drop, a roller coaster ride that takes passengers on a 20-storey drop straight down. There are also exhibits like the Dinosaur Discovery Trail and Bird Paradise. Finally, no trip to Ocean Park would be complete without visiting the park's most popular animals--four giant pandas that were given as a gift from China's central government.

PROBLEM: Article: Compared to high heels , they don't look dangerous, but flip-flop wearers should think twice before slipping on a pair. The National Health Service spends PS40 million a year treating injuries caused by wearing the casual footwear. More than 200,000 people end up in hospital every year after suffering falls or developing long-term problems. Once worn only at the beach, flip-flops have become the regular summer footwear of choice for women, with two in five women owning at least one pair. But experts are warning the public of the dangers of wearing flip-flops, such as the risk of joint pains. They say flip-flops force people to change the way they walk so that when taking a walk with long steps they put pressure on the outside of their foot, rather than their heel, causing long-term damage. And there is also the risk of serious injury. Frequent complaints include twisted ankles, but some have broken their arms or wrists after falling because their flip-flops caught on uneven ground. Many also suffer aching toes as they constantly wear them. Mike, a spokesman, warned wearers of the damage done by flip-flops. He said, "They land on the outside and then roll the foot inwards putting all the pressure on the big toe." This constant rolling puts pressure on the ankle joint, causing it to weaken. The lack of support of the flip-flop also causes pain on the inside of the foot and lower leg. And if you're not used to wearing them, they can cause blisters , he added. Doctors say flip-flops cause far more damage as they are worn for longer periods of time. Emma Supple, consultant podiatrist , said, "Flip-flops are universally popular. They are easy to put on and easy to wear but women do need to be mindful that wearing on hard flat surfaces can cause considerable foot and leg problems." She encouraged women to wear suitable shoes to help recover from summertime injuries.
Question: What is the text mainly about?
Options: (A) The benefits of wearing high heels. (B) The dangers caused by wearing flip-flops. (C) The advantages and disadvantages of wearing flip-flops. (D) Some advice on how to avoid injuries caused by wearing high heels.

SOLUTION: B

PROBLEM: Article: Faces that activate the same regions of the brain again and again are more likely to be remtembered. Practice makes perfect when it comes to remembering things, but exactly how that works has long been a mystery. A study published in Science recently indicates that reactivating neural patterns over and over again my store items into the memory. People find it easier to recall things if material is presented repeatedly at well-spaced intervals rather than all at once. For example, you're more likely to remember a face that your've seen on some occasions over a few days than one that you've seen once in one long period. One reason that a face linked to many different contexts -such as school, work and home- is easier to recognize than one that is associated with just one setting, such as a party, could be that there are some ways to access the memory. This idea, called the encoding variability hypothesis ,was proposed by psychologists about 40 years ago. Each different context or setting activates a clear set of brain regions; the hypothesis suggests that it is these differing neural responses that improve the memory. But neuroimaging research led by Russell Poldrack, a scientist at the University of Texas. Austin, now suggests that the opposite is true--items are better remembered when they activate the same neural patterns with each exposure. Poldrack's team measured brain activity in 24 people using functional magnetic resonance imaging. The subjects saw 120 unfamiliar faces, and each one repeated four times at varying intervals during the scan. One hour later, they were shown the faces again, mixed with 120 new ones, and asked to rate the familiarity of each. The researchers then looked at the brain responses that had been recorded when the subjects wee first shown the faces, focusing on 20 brain regions associated with visual perception and memory. Face that were later recognized evoked similar activation patterns at each repetition in nine of the regions, particularly those associated with object and face perception; faces that were later forgotten did not produce such pattern to the same extent in people's mind
