Whether we like it or not, global climate change will have pronounced effects on the world we live in. Oddly enough, climate change brings with it some minor positive effects. For instance, the frost-free growing season will lengthen. This means that farmers will have a longer period of time in which to grow crops. Ultimately, some farmers may be able to plant and harvest two crops per year, rather than just one. But for every positive effect, there are ten negative ones. Temperatures will continue to rise. Of course, this could spell the doom for polar ice caps. Climate change also brings with it changes in precipitation patterns. More precipitation is expected for the northern U.S., while much less is expected for the Southwest. But perhaps more than anything else, climate change could devastate our coastal cities. Experts estimate that sea levels will rise one to four feet within the next sixty years. So, while not all of the results of climate change are negative, we clearly stand to lose more than we gain.
Which of the following logical inferences can be made based on information found in the passage?

Question

Quizplus · Accepted Answer

The author states that some farmers will be able to plant two crops per year instead of just one. In that way, some farmers will double their annual output.
The effects of climate change will benefit all farmers is incorrect. Not all farmers will benefit. For example, farmers in the Southwest will not benefit from the anticipated lack of precipitation. 
Farmers in the northern states will be forced to relocate is incorrect. Northern farmers may have problems due to the increased precipitation (e.g. flooding), but the author does not imply that northern farmers will have to relocate.
Southwestern farmers will plant more cool weather crops is incorrect. We can guess that the opposite is true. Southwestern farmers will have to plant more hot-weather, drought-resistant crops.
