Along the major rivers that traverse the deserts of northeast Africa, the Middle East, and northwest India, the combination of a reliable supply of water and good growing conditions both encouraged farming traditions that, in places, endure in at least 6,000 years.
good growing conditions both encouraged farming traditions that, in places, endure in
good growing conditions encouraged farming traditions that have, in places, endured for
of good growing conditions have encouraged farming traditions that, in places, endured for
of good growing conditions both encouraged farming traditions that have, in places, endured
of good growing conditions encouraged farming traditions that have, in places, been enduring for
题目分析：
由于语法结构不同，所以在(A)(B)中，具有and关系的两者为water和good growing conditions；在(C)(D)(E)中，具有and关系的两者为a reliable supply of water和good growing conditions。在逻辑上，具有and关系的两者应该保持对等。显然地，“水”和“好的生长条件”在逻辑上是对等的，因此可以排除(C)(D)(E)。此外，(A)中的both没有必要加入，可以排除，答案为(B)。
选项分析：
略
the combination of a reliable supply of water and of good growing conditions表示”水和良好的种植条件的可靠供应，（鼓励了农业传统）“，supply water的意思是供水，一般指人为供水；好的种植条件则更倾向于指包含自然提供的生长条件，比如河流泛滥提供富含有机质的淤泥，因此不说良好的种植条件的供应，改成“水的可靠供应和良好的种植条件，（鼓励了农业传统）”。
endure：忍耐，如：endure sth/doing sth，忍受某事；持续，如：Sth endure for sometime，某事持续。
本题tradition endure for 6000 years，表示传统持续了6000年，endure已经有持续的意思，不再用have been enduring表示从过去到现在到未来一直进行。
