Q: Read the following article and answer the question. Article: Everyone talks about the greenhouse effect and how our Earth and its climate are being affected. We can do a science experiment designed by some kids to show this effect and what is happening to the Earth. First prepare the following items: *2 glass containers that need to be the same size and shape *1 gallon plastic bag *4 cups of very cold water *Ice cubes Fill each container with two cups of cold water. Add the same amount of ice cubes to each container. Then put one of the containers in the plastic bag and close it tight. Put both containers in the sun together and keep them there for at least an hour. At the end of one hour remove the container from the plastic bag and immediately check the temperature of the water. After you record this, find out the temperature of the water that is not covered. When you place the containers in direct sunlight, the air inside the bag becomes very warm. The heat filters in but cannot escape so it stays in the closed plastic bag and increases the temperature. What if you leave that for two, three or four hours? Think about what is happening to the Earth. There are chemicals that are creating a type of plastic bag around the Earth. It causes our air to get warmer because of the heat from the sun being kept in this closed area. Think about your car in the hot summer. This is what happens when you leave your car outside all day. This greenhouse effect has caused your car to be so hot that you sometimes cannot even touch the steering wheel. This science project goes to show what affects our planet. Question: If the story appears in a newspaper, the best title might be " _ ". Answer:

Q: Read the following article and answer the question. Article: When many people see birds cleaning their feathers, . But, in reality, what they are doing is maintaining their wings, the instruments that they depend on for safe flight. If a bird's wings are not in perfect condition, the bird either won't be able to fly or won't be able to control its flight. That is why after a long flight and even throughout the day, you will see them cleaning their feathers. Most birds, if they get a chance, will take a bath at least once a day. They do this to get rid of the dust that has accumulated in their feathers throughout their flight s during the day. In dry or desert areas, birds will not always be able to find water in which to bath, but they still need to clean their feathers. What many birds will do is to take dust baths. They will roll around in dust until it covers their feathers. They will stand up, shaking the dust out, and then clean their feathers with their beaks as usual. Baths are important for another reason. During the course of the day and night, many parasites are attracted to birds. Bugs, mites, fleas and so on will try to reach birds and suck from their blood. Daily baths help to keep the parasites to a minimum. Some birds, especially those that spend a lot of time in or around water, have skin glands that produce oil. After bathing, these birds will squeeze the glands to spread the oil over their wings to keep them free of water. If you are a bird lover and have bird houses in your yard, it can be good to go to the extra step, providing a bird bath. Once the birds in your neighborhood discover it, you will be surprised at how popular it becomes as they periodically stop by to take their daily bath. Question: What's the passage mainly about? Answer:
Answer: Why baths matter so much to birds.
