24. Which choices offers an accurate interpretation of the data in the chart?
A) two years or less of sea otters can completely eliminate sea urchins
B) even two years or less of sea otter presence can reduce the sea urchin threat
C) kelp density increases proportionally as sea urchin density increases
D) even after sea otters were present for ten years or more, kelp density was still lower than sea urchin density
答案: B
答案解析:首先看图表部分的小图表,可得出深色阴影部分代表的是sea urchin的密度,浅色阴影部分代表的是kelp的密度,除此之外每组数据下面都提示了这些数据是根据sea otters的数量发生的改变。再回到答案中直接分析:
A 根据two years or less of sea otters 定位到中间的这组数据,A说sea urchins完全被消除,很明显看深色阴影部分还是有一点点数据的,并没有为零,所以A错误。
B 根据two years or less of sea otters 定位到中间的这组数据,B说可以减少sea urchin的威胁,对比这边这组数据的sea urchins的密度,确实是减少了,B正确。
C sea urchins密度增长的同事kelp的密度也按比例增长,很明显深色阴影部分和浅色阴影部分是一增一减,不可能同时增长,C错误。
D 根据sea otters were present for ten years or more定位到右边的这组数据,答案写的是kelp密度比sea urchin密度小,看图中数据,明显kelp已经疯涨了,而sea urchin完全为零,D错误。
