It may seem surprising today in view of the complex equipment now involved in weather forecasting to understand that in certain cases, the behavior of animals does indeed provide an indication of inclement weather. Sensitivity of certain animals to falling air pressure or to low-frequency sound waves that humans cannot hear, which are indicators of approaching storms, causes behaviors in animals that certain societies have come to recognize as predictors of storms. A number of animals are remarkably sensitive to variations in air pressure, and some of these animals show consistent, noticeable, and predictable behaviors as air pressure drops before a storm hits. Where the air pressure drops before a storm, some animals move closer to the ground to equalize the pressure in their ears: some birds such as swallows tend to stay on the ground or roost in trees instead of soaring in the skies when a storm is imminent because of the decreasing air pressure. Other animals make more noise than usual as air pressure drops: an unusual amount of quacking by ducks and a high volume of croaking by frogs are both indicators that are believed to occur because of the high degree of sensitivity of ducks and frogs to the change in pressure. Finally, still other animals become more active before storms as a reaction to the falling air pressure: dolphins and porpoises seem to be taking part in a frenzied sort of play, and bees and ants become more active prior to storms, most likely because of their sensitivity to lower pressure. There is good reason to believe that the fact that these animal behaviors seem to occur regularly prior to storms may have a scientific basis and that the animals demonstrating these behaviors may actually be good short-range weather forecasters. However, their ability to predict long-range weather patterns is rather suspect. Certain proverbs, for example, are based on what is most likely the idea that squirrels are good indicators of long-range weather patterns. One proverb indicates that, if a squirrel seems busier than usual in gathering nuts, then a long and cold winter is on its way; however, this behavior in squirrels is more likely due to a large supply of nuts available for gathering, which occurs because of earlier good weather, and is not an indicator of cold weather to come. Another proverb about squirrels indicates that if a squirrel grows a long and bushy tail in the fall, then a particularly harsh winter is on its way; in this case too, the squirrel develops a long and bushy tail because of earlier good weather and not as a warning of bad weather to come.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.             The Chinese government has removed pangolin scales from its 2020 list of approved ingredients used in traditional Chinese medicine, a move campaigners describe as a "critical step" towards saving the world's most trafficked mammal. Pangolins are highly valued in Asia for scales, which many people believe can improve blood circulation and reduce inflammation. Last year alone, authorities confiscated more than 130 tons of illegal pangolin related products. There are eight species of pangolin found in Asia and Africa. To date, three species are listed as critically endangered by the International Union for Conservation of Nature, while the remaining five are listed as either vulnerable or endangered. According to Chinese media, the latest edition of Chinese Pharmacopoeia - an official government list of drugs covering approved traditional Chinese and Western medicines - no longer includes pangolin scales. The decision to remove the pangolin from the official list comes just days after China's State Forestry and Grassland Bureau announced that the Chinese pangolin would be upgraded to a "first-level protected wild animal," the highest possible protection status alongside pandas and tigers. While conservationists from China and other countries have praised the actions of Chinese authorities, some still felt that they came a bit too late. "Many years have passed. How many pangolins have already been hunted and killed?" said Sophia Zhang, director of the Pangolin Working Group at the China Biodiversity Conservation and Green Development Foundation.                                       (Adapted from edition.cnn.com) What is the best title for this passage?

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.          The emergence of modern humans are explained on the foundation of  two main hypotheses. The "Out of Africa" theory holds that homo sapiens burst onto the scene as a new species around 150,000 to 200,000 years ago in Africa and subsequently replaced archaic humans such as the Neanderthals. The other model, known as multi-regional evolution or regional continuity, posits far more ancient and diverse roots for our kind. Proponents of this view believe that homo sapiens arose in Africa some 2 million years ago and evolved as a single species spreading across the Old World, with populations in different regions linked through genetic and cultural exchange.        Of these two models, Out of Africa, which was originally developed based on fossil evidence, and supported by much genetic research, has been favored by the majority of evolution scholars. The vast majority of these genetic studies have focused on DNA from living populations, and although some small progress has been made in recovering DNA from Neanderthal that appears to support multi-regionalism, the chance of recovering nuclear DNA from early human fossils is quite slim at present. Fossils thus remain very much a part of the human origins debate.        Another means of gathering theoretical evidence is through bones. Examinations of early modern human skulls from Central Europe and Australia dated to between 20,000 and 30,000 years old have suggested that both groups apparently exhibit traits seen in their Middle Eastern and African predecessors. But the early modern specimens from Central Europe also display Neanderthal traits, and the early modern Australians showed affinities to archaic Homo from Indonesia. Meanwhile, the debate among paleoanthropologists continues, as supporters of the two hypotheses challenge the evidence and conclusions of each other. All of the following statements are true EXCEPT _________

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions       Many of the major supermarket chains have come under fire with accusations of various unethical acts over the past decade. They've wasted tons of food, they've underpaid their suppliers and they've contributed to excessive plastic waste in their packaging, which has had its impact on our environment.        But supermarkets and grocers are starting to sit up and take notice. In response to growing consumer backlash against the huge amounts of plastic waste generated by plastic packaging, some of the largest UK supermarkets have signed up to a pact promising to transform packaging and cut plastic wastage. In a pledge to reuse, recycle or compost all plastic wastage by 2025, supermarkets are now beginning to take some responsibility for the part they play in contributing to the damage to our environment with one major supermarket announcing their plan to eliminate all plastic packaging in their own-brand products by 2023.        In response to criticisms over food waste, some supermarkets are donating some of their food surplus. However, charities estimate that they are only accessing two per cent of supermarkets' total food surplus, so this hardly seems to be solving the problem. Some say that supermarkets are simply not doing enough. Most supermarkets operate under a veil of secrecy when asked for exact figures of food wastage, and without more transparency it is hard to come up with a systematic approach to avoiding waste and to redistributing surplus food.        Some smaller companies are now taking matters into their own hands and offering consumers a greener, more environmentally friendly option. Shops like Berlin's Original Unverpakt and London's Bulk Market are plastic- tree shops that have opened in recent years, encouraging customers to use their own containers or compostable bags. Online grocer Farmdrop eliminates the need for large warehouses and the risk of huge food surplus by delivering fresh produce from local farmers to its customers on a daily basis via electric cars, offering farmers the lion's share of the retail price.        There is no doubt that we still have a long way to go in reducing food waste and plastic waste. But perhaps the major supermarkets might take inspiration from these smaller grocers and gradually move towards a more sustainable future for us all.  (Adapted from https://learnenglish.britishcouncil.org)  Which is the most suitable title for the passage?
