Article: Each time I see a balloon, my mind flies back to a memory of when I was a six-year-old girl. It was a rainy Sunday and my father had recently died. I asked my mom if Dad had gone to heaven. "Yes, honey. Of course." she said. "Can we write him a letter?" She paused, the longest pause of my short life, and answered, "Yes." My heart jumped. "How? Does the mailman go there?" I asked. "No, but I have an idea." Mom drove to a party store and returned with a red balloon. I asked her what it was for. "Just wait, honey. You'll see." Mom told me to write my letter. Eagerly, I got my favorite pen, and poured out my six-year-old heart in the form of blue ink. I wrote about my day, what I learned at school, how Mom was doing, and even about what happened in a story I had read. For a few minutes it was as if Dad were still alive. I gave the letter to Mom. She read it over, and a smile crossed her face. She made a hole in the corner of the letter where she looped the balloon string. We went outside and she gave me the balloon. It was still raining. "Okay, on the count of three, let go. One, two, three." The balloon, carrying my letter, darted upward against the rain. We watched until it was swallowed by the mass of clouds. Later I realized, like the balloon, that Dad had never let his sickness get him down. He was strong. No matter what he suffered, he'd persevere, dart up, and finally transcend this cold world and his sick body. He rose into sky and became something beautiful. I watched until the balloon disappeared into the gray and white and I prayed that his strength was hereditary. I prayed to be a balloon.

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.

Article: If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement. "The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locks because it greatly extends the range of protection with only a few components," Siegel explains on his website. "It is low-cost, durable and easy to use." The Bikealarm was designed as part of Siegel's Bachelor's degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thieves the moment they begin to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram / car and a serious theft. Siegel created a working model of an alarm that would sound when it sensed movement, but wasn't initially sure how it would be best attached to a bicycle. "I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit," he says. Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size. The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasn't signed any agreements to put it on the market.
Question: When it senses movement, the RFID Bikealarm will _ .
Options: (A) make a warning sound (B) fasten the bicycle tightly (C) shake the bicycle quickly (D) call the police automatically
