Based on the way it is used in this passage, what do you think is the closest synonym for arable? a. free b. dry c. infertile d. fertile Analysts disagree about whether the shift in agricultural locations due to global climate change will raise or lower global agricultural output. Because many nations in higher latitudes are more developed and are more equipped to have higher rates of productivity, more food ought to be produced. On the other hand, much of the arable land in these wealthier nations may have already been developed as urban areas, so some food-production potential may not be realized. If crops shift locations, poorer nations may become even weaker economically.The gap between rich and poor nations may grow even wider as developing nations become subject to even harsher environmental conditions for growing crops. However, these nations could make positive adaptations, such as increasing use of water-conserving irrigation techniques and cultivating crops that need less water.

Which of the following is an inference that can be made from the information in the passage? a. Global climate change is not likely to affect worldwide agriculture. b.

The overall effect of global climate change on agriculture cannot be predicted accurately.
