She thought that someone should start raising money for the police dogs. After she got permission from Chief LaBrusciano, she went to the County Sheriff Don Eslinger. She got busy visiting all the police dogs and telling the departments about her new charity. She made "collection boxes" by using bottles and put a picture of her with a police dog on it. She put these bottles in vet's offices and pet stores. The Chief from her hometown police department helped make Stacey's idea an official charity -- Pennies to Protect Police Dogs. The more money she collected, the more popular she became, and the more people offered to donate and help her with her goal of giving every police dog effective protection. Stacey travels all around her state to raise money and tell people how important the police dogs are. She speaks at schools, and they donate to her charity, too. Since Stacey started her charity, she has bought bulletproof vests for the police dogs with all the 140 thousand dollars she has raised. But she has many more K-9 friends that still need to be protected and she promises to keep doing her charity until every police dog in the whole country has a bulletproof vest. Each vest costs $700, and every police dog should have one. There are not always tax dollars to provide K-9s with these vests, and very few departments have them. The police dogs save lives just like police officers do, and often the police dogs are the first to go in. Stacey depends on donations from everyone to provide the dogs with bulletproof vests. Question: What made Stacey begin to consider doing something for the police dogs? Options: A: Chief LaBrusciano's permission. B: The suggestion from a charity. C: A call from the local police department. D: An article about police dogs' problem.

Fast food advertisements significantly affect teens' eating habits, leading to consequences such as obesity. TV Advertising The television is the largest source of food ads to teens. It is worth noting that TV watching may not be the chief cause of obesity, but rather the fast food commercials. This implies that fast food commercials greatly influence teens' eating habits, since food is the most advertised item on television. Online Advertising The Internet has become part of a teen's daily life. Fast food manufacturers have taken advantage of this to target teenagers with food commercials. McDonald's corporation has created websites such as 365Black.com. which target minority groups. MeEncanta. com is a McDonald's website that targets Latino youth, who are four and a half times more likely than other youth to visit the site. Eating Habits There is a strong connection between teens' eating habits and fast food commercials. In a study of more than 12,000 teenagers to inquire into the effects of fast food advertising on teenagers, teens who spent more than two hours watching commercial TV were likely to allow themselves to eat more unhealthy foods like fast foods, sugary drinks and snacks than those who did not. Obesity Teens who view fast food ads are at a higher risk of becoming overweight than those who do not, reports the American Academy of Pediatrics. In a survey of 3,342 youths aged between 15 and 23 researchers found that a higher percentage of obese and overweight participants identified with fast food ads. Question: What's the author's attitude to fast food advertisements? Options: A: Objective. B: Favorable. C: Critical. D: Doubtful.

If so, you probably noted the V-shaped formation of the birds or the birds flying in a ball-like formation. Why do birds fly this way? Many theories have been developed to explain the formation patterns of different types of birds. One theory is that birds fly in certain formations to take advantage of the laws of nature. The birds know that flying in a V-shaped pattern will save energy. Like the lead cyclist in a race who decreases wind force for the cyclists who follow, the lead bird cuts wind force for the birds that follow. This decrease in wind force means that the birds use up to 70 percent less energy during their flight. When the lead bird becomes tired, a more rested bird takes over that position. But saving energy is important for more than one reason. Sometimes food is short during migration flights. Keeping energy enables the birds to fly longer distances between meals. When food is sighted, the birds guide one another in a different way. When a bird identifies a familiar feeding area, it might turn around in order to signal the group to change direction. Then, this bird becomes the new leader. It helps guarantee that other birds will know exactly where it is going. Then the whole group makes a change in direction, gently streaming from the sky down to the ground. This formation is like an arrow pointing to the location of food. Scientists have also studied the birds that sometimes fly in a ball-like formation. Researchers believe that the birds come together if a predator is spotted. The predator may then become impatient waiting for a single bird to fly away from the group. The birds will often dip and dive as a group, frustrating even the most persistent enemy. Scientists report that this is a very effective method of defense against an attack. The birds care for their fellow fliers through teamwork. As transportation expert Henry Ford once said, "If everyone is moving forward together, then... Question: Which is the best title for the passage? Options: A: A Bird's-Eye View of Teamwork. B: Success Takes Care of Itself. C: The Strongest Will Survive. D: A Science Behind Flying.
