Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.
The costs and benefits of global warming will vary greatly from area to area. For moderate climate change, the balance can be difficult to assess. But the larger the change in climate, the more negative the consequences will become. Global warming will probably make life harder, not easier, for most people. This is mainly because we have already built enormous infrastructure based on the climate we now have.
People in some temperate zones may benefit from milder winters, more abundant rainfall, and expanding crop production zones. But people in other areas will suffer from increased heat waves, coastal erosion, rising sea level, more erratic rainfall, and droughts.
The crops, natural vegetation, and domesticated and wild animals (including seafood) that sustain people in a given area may be unable to adapt to local or regional changes in climate. The ranges of diseases and insect pests that are limited by temperature may expand, if other environmental conditions are also favourable.
In its summary report on the impacts of climate change, the Intergovernmental Panel on Climate Change stated, "Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.”
