【分析】
本文是一篇说明文。科学家们通过研究发现醋酸盐能够提高植物的耐旱性。醋里含有醋酸盐，这就意味着，在将来有可能用醋来解决干旱地区的种植问题，进而解决饥饿问题。
【详解】1. 细节理解题。根据第三段第一句“The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather.”（这一发现是在研究人员研究了拟南芥之后发现的，拟南芥是一种以能够在干燥天气中生存而闻名的植物）可知，Arabidopsis的特点之一是耐旱。故选D。
2.推理判断题。根据第四段第二句“After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died.”（在离开这些植物14天后，他们发现用醋酸盐处理的植物存活了下来，而没有处理的植物已经干枯死亡。）可知，做实验的目的是检验把醋酸盐添加到其他植物中能否增加该植物的耐旱性。故选C。
3.推理判断题。根据最后一段“And for those of us who always forget to ask our neighbors to water our plants when we go away, hopefully this means the end of returning home from a trip to find our favorite flowers have died.”（对于我们这些出门总是忘记让邻居给植物浇水的人来说，希望这意味着我们旅行回到家，发现我们最喜欢的花已经死了现象的结束。）以及第一段作者对醋的描述可知，作者对于这种方法持乐观的态度。故选D。
4.主旨大意题。根据第一段中的第二句“And now, according to scientists, it may even help the planet's population survive climate change.”（而现在，据科学家称，它甚至可以帮助地球人口在气候变化中生存）可知，醋能帮助农作物在干旱的环境中生存，有了农作物，人类的生存问题也得到了解决。A.Vinegar May End Hunger(醋或许可以终结饥饿)能够概括全文。B项存在知识性错误，植物不可能永生，C项范围过大，D项 “植物需要水”不是文章主要讲述的，均可排除。故选A。
