Read the following article and select the best answer. Article: Mass media are tools of communication. They allow us to record and pass information rapidly to a large, scattered audience. They extend our ability to each other by helping us overcome limits caused by time and space. Mass media can be divided into two groups: print media and electronic media. By print media, we mean books, newspapers and magazines. Electronic media include television, radio and movie. There are a number of ways in which mass media make daily life easier for us. First, they inform and help us keep a watch on our world. They gather and pass on information we would be unlikely or unable to gain on our own. Second, mass media help us to arrange our time and life. What we talk about and what we think about are greatly influenced by the media. When people get together, they tend to talk about certain happenings on the newspapers or on TV. Because we are provided with differing points of view through different kinds of media every day, we are able to comment on all sides of a certain issue. Third, mass media help us to connect with various groups in society. Through mass media, we are able to keep in contact with politicians in the world; with famous actors and actresses, and with our beloved singers. Fourth, the media help to socialize us. We learn about the preferred behavior and values from the people we meet as well as from the media. Through portrayals of people, the media tell us what proper behaviors are. By doing so, they teach us standards of behavior and values, and help us in our daily life. Fifth, the media are used to persuade people. A good example is advertisements through the media. Newspapers, magazines and TV are filled with all kinds of colorful, persuasive advertisements. Though many advertisements may not say openly that they want you to buy a certain product, they describe their products in such a way that you may want to but them. Sixth, the media entertain. All of the media make some effort trying to entertain their audience. For example, even though the newspaper is a main...

Question: Read the following article and select the best answer. Article: With the development of society and economy, animals and their habitats are getting pushed aside as households decrease in size and increase in number. Small numbers of people per household on average use more energy and goods per person. Greater numbers of households require more natural resources for construction. The possible result of this problem may be _ natural resources to meet consumer demand without endangering habitats important to biodiversity. Personal freedom and social choice may come at huge environmental cost. Direct costs include visible damage to animal habitats and plant life. Indirect costs include the release of more greenhouse gases. The effects of such "personal freedom and social choice" have already surfaced in south-west China's Wolong Nature Reserve. In Wolong, they found that a reduced average household size was directly tied to an increase in homes, and thus an increase in the amount of firewood consumed for cooking and heating. The rise in wood fuel use has contributed to disappearance of forests and to the loss of habitats for giant pandas. Curious about whether other parts of the world were experiencing similar phenomena, they got the support of a team of researchers including Stanford's Paul Ehrlich, well-known for his population studies, to find out the household dynamics in 141 countries between 1985 and 2000. Their study proved that the difficult choice of Wolong is part of a global trend. In the 76 countries considered biodiversity "hotspots", such as the United States, Brazil, Australia, and Kenya, the number of households grew by 3.1% every year, while the population increased just 1.8%. Meanwhile, the number of people per home dropped from 4.7 to 4.0. The decline in household size has resulted in 155 million additional households in hotspot countries, almost always limiting biodiversity. In the 10 non-hotspot countries -- those without high-density areas of animal and plant species -- similar results were found, though on a lesser scale. Even in countries experiencing... Question: What does the passage mainly talk about? - Reduced household size leads to an increase in household number. - Modern homes consume more natural resources. - How to meet consumer demand without endangering animals and their habitats. - Reduction in household size as well as increase in household number threatens nature.
Answer:
Reduction in household size as well as increase in household number threatens nature.
