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.

Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.

Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.

However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments.

With which of the following statements would the author be most likely to agree?

A. The extinction of a few species is an acceptable consequence of human progress.

B. Technology will provide solutions to problems caused by the destruction of ecosystems.

C. Human influence on ecosystems should not be a factor in determining public policy.

D. Humans should be more conscious of the influence they have on ecosystems.

The reason women appear to be at greater risk of developing Alzheimer’s disease than men might be due to a number of genetic, anatomical and even social influences, researchers have suggested. Recent figures show about 65% of those with living with dementia in the UK are women, with a similar statistic seen in the US for Alzheimer’s disease, while dementia is the leading cause of death for women in England. Alzheimer’s disease is only one of the types of dementia, but the most common form. While one explanation is that dementia risk increases with age, and women have longer life expectancies than men, new research suggests there might be more to the matter, including that protein tangles found within neurons and linked to Alzheimer’s disease might spread differently in women’s brains than men’s. The study, presented at the Alzheimer’s Association International Conference in Los Angeles by researchers from Vanderbilt University and which has not yet been peer-reviewed, used scans from a method called positron emission tomography. That allowed them to look at the way clumps of a protein called tau were spread in the brains of 123 men and 178 women without cognitive problems, as well as 101 men and 60 women with mild cognitive problems – although not yet diagnosed with Alzheimer’s disease. Cognitively normal older people often have small amounts of tau in certain areas of their brain. From the data the team could build maps showing which areas of the brain show similar signals relating to tau in the scans, suggesting they are somehow connected. “Based on that we kind of try to reconstruct the pattern of spread,” Dr Sepideh Shokouhi, who is presenting the research, told the Guardian. “It is kind of like reconstructing a crime scene.” The team says the results suggest these maps look different in women and men, suggesting tau might be able to spread more rapidly across the female brain.

Other research presented at the conference – and also not yet peer reviewed – added weight to the idea that there might be differences between men and women that affect dementia risk. Research by scientists at the University of Miami has revealed a handful of genes and genetic variants appear to be linked to Alzheimer’s disease in just one biological sex or the other. While the actual importance of these factors has yet to be unpicked, and the study only looked at white participants, the team says it underscores that there could be a genetic reason for differences in the risk of dementia in men and women, and the way it develops.

Which of the following could be the best title of the passage?

A.The differences between male and female brain and the condition for Alzheimer’s.

B.Research shines light on why women are more likely to develop Alzheimer’s.

C.The method for treating Alzheimer’s in women

D.Alzheimer’s – the leading cause of death for women.
