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.

Question. In paragraph 2, non-native species are mentioned as ______.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

All over the country, young people are entering a world of homelessness and poverty, according to a recent report by the housing group, Shelter.

Nearly 150,000 young people aged between sixteen and twenty-five will become homeless this year, says Shelter. Some of the young homeless may sleep out in the open in such places as the "cardboard city” in London, where people of all ages sleep in the open air in their only homes - cardboard boxes. Others may find accommodation in shelters run by voluntary organisations or get a place in a hostel, which gives them board up to ten weeks.

But who are these people? Those who are seeking a roof over their heads are mostly not runaways but “throwaways" - people who have been thrown out of their homes or forced to leave because of parental divorce, an unsympathetic step-parent or one of many other reasons.

Take the case of one sixteen-year-old schoolgirl, Alice. She did not come from a poor home and had just passed her exams with good results. The Shelter team met her in a hostel where she was doing her physics homework. Her parents had thrown her out of her home for no other reason that she wanted to do Science Advanced Level Exams - which her parents refused her permission to do, saying that studying sciences was unladylike!

Shelter says that the government's laws do nothing to help these youngsters. Rising rents, the shortage of cheap housing and the cut in benefits for young people under the age of twenty-five are causing a national problem, according to Shelter. The recent changes in the benefit laws mean that someone aged between sixteen and twenty-five gets less than older people and they can only claim state help if they prove that they left home for a good reason.

Shelter believes that because of the major cuts in benefits to young people, more and more are being forced to sleep on the streets. Shelter also points out that if you are homeless, you can't get a job because employers will not hire someone without a permanent address; and if you can't get a job, you are homeless because you don't have any money to pay for accommodation. It's an impossible situation.

Question. According to a recent report by Shelter, it appears that ____.
