Cola removes the tarnish from old pennies. Got some old rusty pennies? Not to worry! Put them inside a glass of cola and let them rest for a while. When you get them out, you'll have shiny pennies that will look as if they were coined a couple of days ago. If you couldn't clean those pennies with industrial acids, just buy a can of cola and let it do its magic! You can remove gum from your hair with cola. If you've got gum stuck in your hair and don't know a better way to get it out, don't worry, you won't have to cut it. Just pour some cola into a bowl and dip the part of your hair with gum on it inside. Leave it for a couple of minutes and then simply wipe off the gum. You can make an exploding fountain. You probably know about this one. You can make an exploding fountain by putting a mint inside a two-liter bottle. Then move away from the bottle and get ready for a Coca-Cola explosion.

Q: Read the article and select the best answer. Article: All presentations should include the beginning, the middle, and the end. The first part of your presentation should always present the problem. The middle of the presentation should present your key findings. By the end of the presentation, your audience should have a better understanding of the solution. Less is more. There's a tendency to make a presentation slide excessively complicated with flashy images, strange transitions, and too much text. These features are often unnecessary, and tend to make the viewers get bored. Instead, keep each slide short and plain, using one image to sell your idea. Using bullets is a bit of a cliche , but if you must use them, never exceed more than one line of text per bullet. Branding is the key. Whether you're stating a new business idea to investors or describing a new product to customers, you'll want your presentation to reinforce your brand's image. Use the same color1 schemes, fonts , and logos that you use on your website or company literature. There's an assumption of what a Power Point is supposed to look like, and company standards falls through the floor. Give them a break. According to a recent research, the average adult attention span for a presentation is just 20 minutes. It's always best to keep your presentation short and to the point, but if you must exceed the recommended 20 minutes, try giving your audience a moment to relax. "You can extend attention spans by giving your audience a rest," the study says. This can be done by telling a story, giving a demo, or doing something else that gives the brain a break. Practice it again and again. In the end, a great presentation will come down to the speaker's ability to capture the audience's imagination and keep their attention. The presentation and the speaker should work together and they can be complementary to each other. The best presenters won't have to look down at the notes and will never be reading from a script. A good speaker can focus on the key points and convey information well. Question: What can be the best title for this passage? Options: A: Four Tips for a Great PowerPoint Presentation B: The Importance of a PowerPoint Presentation C: The Benefits of Using a PowerPoint Presentation D: The Proper Occasion for a PowerPoint Presentation

Q: Read the article and select the best answer. Article: Even bird brains can get to know an entire continent ----- but it takes them a year of migration to do so, suggests a Princeton research team. The scientists have shown that migration adult sparrows can find their way to their winter nesting grounds even after being thrown off course by thousands of miles. The team first brought 30 sparrows to Princeton from northern Washington State, where the birds had been in the process of migrating southward from their summer breeding grounds inprefix = st1 /Alaska. Half the birds were juveniles of about three months in age that had never migrated before, while the other half were adults that had made the round trip to their wintering site in the south-western United States at least once. After the birds were released, they attempted to resume their migration, but both age group grew disoriented quickly. "All the birds scattered at first," Wikelski said. "It was clear that they were turned around for a couple of days. But while the adults eventually realized they had to head southwest, the younger birds resumed flying straight southward as though they were still in Washington." "The adults," said team member Richard Holland, "recovered their bearings because they possess something the younger birds do not, which is an internal map." "These birds need two things to know where they are and migrate effectively: a 'map' and a 'compass'," saidHolland, a postdoctoral research associate in Wikelski's lab. "What we've found is that juveniles use their compass, but the adults also use their map." Hollandsaid, "The birds do not lose the compass as they age, but somehow develop the map, eventually applying both tools to keep on track during migratory flights. Scientists already have determined that the compass is based on the sun or the magnetic field, but where the map comes from remains a mystery----one that the team will be exploring in coming years." Question: We can know from the passage that the juveniles of sparrows _ . Options: A: will follow the adults in their flights B: will find their destination eventually C: will lose the compass as they age D: still lack an internal map
A: D
