OG 73 Combining enormous physical strength with higher intelligence, the Neanderthals appear as equipped for facing any obstacle the environment could put in their path, but their relatively sudden disappearance during the Paleolithic era indicates that an inability to adapt to some environmental change led to their extinction. ---> OG 上的解释是说as equipped does not indicate the past tense, therefore, you must change it to have been equipped. 不明比这里为何要用过去完成时， equipped不就是过去式么？为什么没有relfect past tense呢？
75. whether tourists will continue to visit game parks to see one once their horns are--> 我知道这里的one 是错误的，但是GMAT里好像出现one的次数不多，请问正确的one的形式应该是神马样子的，或者GMAT里会怎样出题？
77. The only way for growers to salvage frozen citrus is to process them quickly into juice concentrate before they rot when warmer weather returns--> 这里的A,B,C 选项解释的都是they/them 与citrus 的单位不统一，但是我这里的them/they 可不可以看成是歧义？ they/them 可能会指代的是growers?
