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.
Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature.
In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.
As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.

A.Humans will make changes in their lifestyles to save other species.

D.The dilemma humans face between maintaining their lives and saving other species remains.

PERCEPTIONS OF ANIMALS ACROSS CULTURES
When living and working in another country, there are numerous things to consider apart from the more obvious ones of climate, language, religion, currency, etc. Some important considerations are less obvious. For example, do you have a pet or do you enjoy a hobby such as horse riding? Your animal or hobby may be perceived in a completely different light in another culture so it’s important to consider the significance given to specific animals in different parts of the world and general perceptions towards them.
One example which is often mentioned in popular press is the case of dogs. In some cultures, like the US or UK, dogs are loved and considered a great pet to have at home and with the family. In other cultures, such as those where Islam is the majority religion, dogs may be perceived as dirty or dangerous. Muslims treatment of dogs is still a matter of debate amongst Islamic scholars. While these animals are widely considered by many Western cultures to be ‘man’s best friend’, the Koran describes them as “unhygienic”. Muslims will therefore avoid touching a dog unless he can wash his hands immediately afterwards, and they will almost never keep a dog in their home.
In Iran, for instance, a cleric once denounced ‘the moral depravity’ of dog owners and even demanded their arrest. If you are an international assignee living and working in Saudi Arabia or another Arabic country, you should remember this when inviting Arab counterparts to your house in case you have a dog as a pet. This is just one example of how Islam and other cultural beliefs can impact on aspects of everyday life that someone else may not even question. A Middle Eastern man might be very surprised when going to Japan, for instance, and seeing dogs being dressed and pampered like humans and carried around in baby prams!
Dogs are not the only animals which are perceived quite differently from one culture to another. In India, for example, cows are sacred and are treated with the utmost respect. Conversely in Argentina, beef is a symbol of national pride because of its tradition and the high quality of its cuts. An Indian working in Argentina who has not done his research or participated in a cross cultural training programme such as Doing Business in Argentina may be surprised at his first welcome dinner with his Argentinean counterparts where a main dish of beef would be served.
It is therefore crucial to be aware of the specific values assigned to objects or animals in different cultures to avoid faux-pas or cultural misunderstandings, particularly when living and working in another culture. Learning how people value animals and other symbols around the world is one of the numerous cultural examples discussed in Communicaid’s intercultural training courses. Understanding how your international colleagues may perceive certain animals can help you ensure you aren’t insensitive and it may even provide you with a good topic for conversation.

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.
Most of the early houses built in America were suited to farm life, as it was not until cities became manufacturing centers that colonists could survive without farming as their major occupation. Among the earliest farmhouses in America were those built in Plymouth Colony. Generally they consisted of one large rectangular room on the ground floor, called a hall or great room and having a fireplace built into one of the walls, and a loft overhead. Sometimes a lean-to was attached alongside the house to store objects such as spinning wheels, firewood, barrels, and tubs. The furnishings in the great room were sparse and crudely built. Tabletops and chest boards were split or roughly sawed and often smoothed only on one side. Benches took the place of chairs, and the table usually had a trestle base so it could be dismantled when extra space was required. One or two beds and a six-board chest were located in one corner of the room. The fireplace was used for heat and light, and a bench often placed nearby for children and elders, in the area called the inglenook.
The original houses in Plymouth Colony were erected within a tall fence for fortification. However, by 1630 Plymouth Colony had 250 inhabitants, most living outside the enclosure. By 1640, settlements had been built some distance from the original site. Villages began to emerge throughout Massachusetts and farmhouses were less crudely built. Windows brought light into homes and the furnishings and décor were more sophisticated.
As more diversified groups of immigrants settled the country, a greater variety of farmhouses appeared, from Swedish long-style houses in the Delaware Valley to saltbox houses in Connecticut, Dutch-Flemish stone farmhouses in New York, and clapboard farmhouses in Pennsylvania. From Georgian characteristics to Greek revival elements, farmhouses of varied architectural styles and building functions populated the landscape of the new frontier.
The main idea of the passage is
A.The history of the American farmhouse
B.Where immigrants settled in America
C.How to build an American farmhouse  
D.life in Plymouth Colony
