Understanding India's Caste System
It has been said that life is what we make of it. In other words, if we work hard and focus on our goals, we can have great careers and enjoy high status is society. However, these opportunities don’t exist for everyone. In some places, the family you are born into will decide almost everything about your life. India’s caste system is an example of this.
The caste system is a major part of the Hindu religion that has existed for thousands of years. It is a way of organizing and grouping people based on the occupation of the family. Castes will determine whom people can socialize with and their place in society. Originally, a person’s caste was supposed to be determined by their personality, but over time it has been linked to their job and family.
There are four classes, also known as varnas, in India’s caste system. The highest one is Brahmin. People in this class have jobs in education and religion. These are seen as extremely important functions for the society as they deal with the knowledge. The second highest level is the Kshatriya, or ruling class. People from this group can be soldiers, landowners, or have jobs in politics. The class beneath this is the Vaishya. These people often work in the commercial sector as merchants. The fourth class level is the Shudra. Shudras typically work as unskilled labourers doing factory or farm work, or they may also be employed as artists.
There is another group, the Harijan, that is at the bottom and considered to be outside of the caste system. For many years, they were known as Untouchables, people from this caste held the most undesirable jobs in society, such as cleaning up garbage. Furthermore, they weren’t allowed to pray at public temples or drink water from the same wells as other classes. If someone from another caste came into contact with an Untouchable, they were considered dirty and would be expected to bathe vigorously to clean themselves.
Although the caste system still exists in India, the government is taking steps to improve the living conditions and decrease unemployment rates for the Shudras and Harijan. This includes providing better health care, offering literacy programmes, and making sure that people from higher social classes do not exploit them. It seems unlikely that the caste system will disappear any time soon, but the overall conditions for those at the bottom do seem to be improving.

A.The caste system has been used in India for a long time.
B.The Kshatriya is the second highest class.
C.Hard work helps people move up in the caste system.

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 from 35 to 42.
Nature has always provided a stimulus for inventive minds. Early flying machines clearly were an attempt to emulate the freedom of birds. Architects and engineers have often consciously modeled buildings on forms found in nature. A more recent example of the inspiration given by nature is the invention of Velcro®. The inventor of this now common fastening device noticed that small burrs attached to his dog's coat grasped the hairs by means of tiny hooks. This led him to invent a synthetic fabric whose surfaces mimic the clasping properties of this natural seedpod.
   Animals and plants have evolved solutions to the kinds of problems that often interest engineers and designers. Much current research in material science is concerned with actively examining the natural world, especially at the molecular level, for inspiration to develop materials with novel properties. This relatively new field of study is sometimes known as biomimetics, since it consciously attempts to mimic nature.
Researchers have investigated several interesting areas. For example, they have studied how the molecular structure of antler bone contributes to its amazing toughness, how the skin structure of a worm contributes to its ability to crawl, how the sea cucumber softens its skeleton and changes shape so that it can squeeze through tiny gaps in rocks, or what gives wood its high resistance to impact. These investigations have led to several breakthroughs in the development of composite materials with remarkable properties.
Predictions for future inventions that may be developed from these lines of research include so-called smart structures that design and repair themselves in a similar way to a variety of processes in the natural world. For example, engineers have envisaged bridges that would detect areas heavily stressed by vehicle movement or wind. The bridge structure would then automatically add or move material to the weak areas until the stress is reduced. The same principle might be used to repair damaged buildings. Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources. The potential impact of biomimetic research is so great that the twenty-first century may come to be known as the "Age of Materials."
As inferred from the passage, what would be the advantage of a product that mimics photosynthesis?
 
A.It could be used to create green plants.       
B.It could help to meet future energy needs.
C.It could be an aid in repairing green areas.   
D.It could form the basis of twenty-first century materials.

A.girl
B.man
C.lady
