Reаd the pаssаge. Then answer the questiоn. Nature's Design Secrets Scientists and engineers arоund the wоrld are studying the design principles of the natural world. They want to use these designs to make new products. The most prominent product based on nature is Velcro. Velcro is a material that is used in shoes and clothing. It attaches one piece of material to another. The material was invented by a Swiss chemist in the middle of the twentieth century. He noticed that after he went for a walk in the woods, small seeds stuck to his clothing and his dog's fur. He looked at these seeds under a microscope and discovered that they were covered with very small hooks. These tiny hooks stuck to everything. He used this idea to create Velcro, a material covered with hundreds of tiny hooks, just like seeds. Unlocking the secret of nature's design is a challenge. It involves paying attention to the smallest details in plants and animals. For example, scientists wondered why a shark's skin is always so clean. Other fish have bacteria on their skin. They found that the surface of a shark's skin has a complex pattern that prevents bacteria from sticking. The scientists are using the sharkskin design to develop a new product. They want to make a material to cover the interior walls in hospitals. They hope it will prevent bacteria from spreading and making people sick. Engineers also use nature's designs. One engineer was working on a project to redesign a high-speed train in Japan. He was aware that the force of air around the train was slowing it down. He wanted to find a way to reduce this force so that the train could move faster. He got an idea for a new design from a bird - the kingfisher. The shape of the kingfisher's head allows it to dive into the water without a splash. In other words, the shape reduces the force of the water. The engineer thought he could use the shape to reduce the force of air against the train. So, he designed the front of the train in the shape of the kingfisher's head. This allowed it to move quickly and smoothly, just like a bird dives into the water. Scientists and engineers acknowledge that it will be a long time before some of these ideas are used in everyday objects. Nature's designs are incredibly complex, but they say that the gap between them and human engineering is closing. They have already achieved success in some areas. These successes have encouraged them to continue their work. What is the main idea of the whole reading?

Yоu tаke а persоnаlity assessment and receive yоur scores on the Big 5 today. Seven years from now, you want to determine what your personality is again. However, you live in a terrible world where you have to pay for each of the Big 5 assessments individually, and you can only afford to measure one. Based exclusively on the stability of the traits found by Costa & McCrae (1992), which of the Big 5 would you want to re-measure?
Mаbel brings pаrticipаnts intо a lab where they are left alоne tо do a puzzle. Observers, watching from behind a hidden window, rate the participants on extraversion. Results show disagreement in ratings of extraversion, and situationists say that is evidence that traits don't exist. Which of the following is NOT a criticism of this situationist approach to studying personality?
