What can people know from the crown of an ancient tree found in New York? [br] What possibly resulted in the evolution from leafless tree to flat leaves?
选项
A、The decrease CO2 in levels.
B、The increase of forests.
C、The drop of temperatures.
D、The change of climates like today.
答案
A
解析
根据题干中the evolution…to flat leaves,可以定位到第六段第二句。这句提到二氧化碳的下降可能导致了阔叶树木的进化,因为阔叶可以吸收并保持更多的植物所需的气体(flat leaves on trees to attract and retain more of the gas)。森林数量的增长并未导致阔叶树木的进化,故可排除B;温度的下降以及气候变成了像现代的样子也不是导致阔叶树木进化的原因,故可排除C、D。
