I'm taking a test and have to guess the right answer to the question after the article. Article: Amazon. com has received a patent right to send its products to customers by drone planes. The company is the largest US-based online seller of products by mail and other services. Now, the company has received a patent for its planned drone delivery system. In March, federal officials allowed Amazon to test its drone delivery plan. But even with a patent and the ability of drones to make deliveries, it does not appear the company will put its new delivery system in place any time soon. The US Patent Office published the document, which describes Amazon's plans to use GPS to deliver products to homes and to wherever people are. The drone will use a customer's mobile device --- usually a smartphone ---to avoid hitting people or buildings and to find a _ area to land. The company wants to deliver products within 30 minutes after people order them on its website.[:++Z+X+X+K] However, the Federal Aviation Administration (FAA) is worried about the safety. Although it allowed Amazon to test the system, the agency said the operators must be able to see the planes. That greatly limits the delivery area. Loretta Alkalay is a professor at the Vaughn College of Aeronautics and Technology in New York. Although Amazon is not yet offering drone delivery, Professor Alkalay says it will not be long before it does. She says there are worries that the drones will hit buildings or people, or that the products and drones will be stolen or damaged by people on purpose. But she says that is because many people believe the drones would only deliver the products to the front door of a house. "However, it is possible that homes will one day have special area on their roofs designed to receive product deliveries," she adds. Question: After reading the passage, we can infer that FAA _ Options: A: doesn't really like Amazon B: totally support the drone delivery system C: doesn't think Amazon should get the patent D: doubts about the drone delivery system

I'm taking a test and have to guess the right answer to the question after the article. Article: There are some places in the world where great cities once stood. There were trees, gardens and grass. But now these cities have gone and the places are like deserts. Scientists began to study this land to find out what happened. Many of them believed the land died when the trees were cut down. Trees help other plants grow and help hold the soil in place. They keep the soil from blowing away. The leaves of trees on the ground keep rainwater from running off. Trees near farms protect growing plants from strong winds. Once there were hundreds of farms in the southwestern United States. Then the farms turned into fields of dry dust. Trees might have saved these farms. But few trees grow in the dry southwest now. Now we try to save trees. In many places, when a tree is cut down , a new tree is planted in its place . We do not want the land to die. Question: What can trees do according to the passage ? Options: A: Trees can keep other plants green B: Trees can help other plants grow . C: Trees can help the land grow . D: Trees can keep other plants in place .

I'm taking a test and have to guess the right answer to the question after the article. Article: When your pet meets your infant ,it might not be love at first sniff. When Jennifer brought her baby home from the hospital, her cherished dogs had very different reactions. Her Boxer, Sonya, was immediately gentle and protective. But Tiger, the Pomeranian, was less welcoming. "If any diapers or toys were on the floor, he peed on them," says the Greenbrier, mom. In the eyes of a pet, there's a new star in home who's stealing his spotlight. Even the gentlest animal will probably act up if he doesn't get his usual attention. These simple steps will help your pet adjust and keep your baby safe. Introduce Them with Care Your newborn and per's first encounter can set the tone for their relationship. To make it as smooth as possible, try this trick from Caryn Ruiz:"Before we left the hospital, my husband took blankets home to our dog, Daisy, so she'd know our newborn Devon's smell." When you get home, have your husband carry the baby so you can greet your pet without worrying about her jumping on you. A cat will likely walk away at first, while a dog probably wants to investigate right away. To introduce your baby, get down on your pet's level and let her have a hello sniff. Don't panic and pull your baby away unless your pet is barking or hissing, because it'll send the message that the baby is a threat. Learn the Safety Basics No matter how smoothly the introduction goes, there are certain safety rules you should follow. Never leave your baby alone with the pet. Even the gentlest animal can react unpredictably. Your baby's crying could frighten your cat, or your dog could suddenly become territorial. Consider setting up baby gates to limit your pet's access. To keep your cat from jumping into the bassinet , try putting mosquito netting over the top. Cats hate sticky paws, so keep the crib and changing table off-limits by lining the edges with sticky strips made for furniture. You can also train your dog to sleep in a crate . Question: What can we infer from the passage? Options: A: Cats are more welcoming than dogs when they meet a newborn baby. B: You must show your baby to your pet dog when it is barking. C: You should never keep a baby together with your pet. D: The first introduction of your newborn baby to your pet is important.

I'm taking a test and have to guess the right answer to the question after the article. Article: Recently Dr. Cleiman has proved that everyone has a daily energy cycle. During the hours when you labor (work) through your work, you may say that you are "hot". That is true, the time of day when you feel most energetic is when your cycle of body temperature is at its peak . For some people the peak comes during the forenoon . For others it comes in the afternoon or evening. No one has discovered why this is so. Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has. You cannot change your cycle, but you can learn to make your life fit it better. "Habits can help," Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point. Get off to a slow start which saves your energy. Get up with a lazy yawn and stretch . Sit on the edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying them out the night before. Question: Dr. Cleiman did not explain in the passage _ . Options: A: how people can make their life fit their cycle B: whether everyone has a daily cycle or not C: why people have their energy cycle at different times D: what will happen in the family if the couple fail to realize which cycle each member has
