题目解答
答案
A. They will increase carbon emissions due to more travel.
解析
本题考查对自动驾驶汽车对碳排放影响相关知识的理解。解题思路是分析每个选项所描述的自动驾驶汽车对碳排放的影响是否合理。
- 选项A:
- 自动驾驶汽车可能会因为人们更愿意出行,比如原本因为驾驶不便而放弃的出行现在因为自动驾驶变得可行,从而导致出行次数增多。
- 出行次数增多意味着汽车行驶里程增加,在汽车能源消耗不变或者增加的情况下,碳排放就会相应增加。所以该选项有一定的合理性。
- 选项B:
- 虽然自动驾驶汽车可能在某些方面提高效率,例如优化驾驶路线、保持稳定的车速等,但这并不一定就会直接导致碳排放减少。
- 因为如果出行需求大幅增加,即使效率提高,总的碳排放也可能不会减少甚至会增加。所以该选项不准确。
- 选项C:
- 自动驾驶汽车的使用会改变人们的出行行为和汽车的使用情况,必然会对碳排放产生影响,而不是没有影响。所以该选项错误。
- 选项D:
- 即使自动驾驶汽车不是电动的,也可能因为出行需求的变化而影响碳排放,并非只有电动的自动驾驶汽车才能减少排放。所以该选项过于绝对。
