I'm taking a test and have to guess the right answer to the question after the article. Article: Most of us have gone away from "mad men" in the street, only to realize that they are in fact using a Bluetooth headset. Now a new University of Pennsylvania study shows that muttering can actually help people find lost objects--in other words, saying the name of an object helps you find it more quickly. Previous work has suggested that speaking aloud while performing step-by-step tasks, like tying shoelaces ,can help kids guide their behavior and let them focus on the job in hand. However, scientists were not sure if speaking aloud when performing tasks could help adults in the same way, especially when looking for particular objects. Professor Gary Lupan and Daniel Swingley, writing for the Quarterly Journal of Experimental Psychology, carried out some experiments. They hoped to give the fact that next time you lose your keys, muttering " keys,keys,keys"can in fact help you find them. Inspired by viewing people muttering to themselves as they try to find things like peanut butter in a supermarket, the researchers conducted two experiments to see if this actually worked. In the first, participants were shown 20 pictures of various objects and were asked to find a certain one, with some seeing a text label telling them what they were looking for. These participants were then asked to search for the object again while saying the word to themselves, with results showing that saying it aloud helped people find the object more quickly. The second experiment saw participants performing a shopping task, where they were shown photographs of items commonly found on supermarket shelves. They were asked to find all examples of a particular item, so if they were asked for apples they had to find all the bags of apples, as quickly as possible. The researchers found that there was also an advantage in saying the name of the product aloud when they were searching for something familiar. The University of Pennsylvania study shows that muttering can actually help people reach the target object--in other words, muttering... Question: What is the best title of the passage?

I'm taking a test and have to guess the right answer to the question after the article. Article: When a Swedish ship that sank in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago. Underwater archaeology-----the study of ships, aircrafts and human settlements that have sunk under large bodies of water-----is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment. Besides the Swedish ship wreck ,underwater archaeologists have made more exciting discoveries such as the 5000-year-old boats in the Mediterranean Sea. Underwater archaeology can provide facts about the past. In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of people's way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world's knowledge of history, but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater "museums" of the past, archaeologists are hoping to get support for laws to protect underwater treasures. Question: The aim of underwater archaeology is to _ . Options: A: explore water bodies B: search for underwater life C: study underwater artifacts D: examine underwater environment

I'm taking a test and have to guess the right answer to the question after the article. Article: A villa designed to resist earthquakes with "self-healing" cracks in its walls, thanks to nanotechnology applications with self-healing polymers , is to be built on a Greek mountainside. The villa's walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called "Intelligent Safe and Secure Buildings" (ISSB) is funded under the EU's Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, "What we're trying to achieve here is very exciting. We're looking to use polymers in much tougher situations than ever before on a larger scale." Monitors contained in the villa's walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations, as well as temperature, humidity and gas levels. The walls are to be built from new load-bearing steel frames and high-strength gypsum board. Prof Wilkins said, "If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue." Question: What Prof Wilkins said suggests that _ . Options: A: he is doubtful about the project B: he thinks the tremor-resistant home is perfectly designed C: he is confident in the tremor-resistant home D: the tremor-resistant home still needs to be tested in a real situation
