Micro-wear patterns found on the teeth of long-extinct specimens of the primate species australopithecine may provide evidence about their diets. For example, on the basis of tooth micro-wear patterns, Walker dismisses Jolly’s hypothesis that australopithecines ate hard seeds. He also disputes Szalay’s suggestion that the heavy enamel of australopithecine teeth is an adaptation to bone crunching, since both seed cracking and bone crunching produce distinctive micro-wear characteristics on teeth. His conclusion that australopithecines were frugivores (fruit eaters) is based upon his observation that the tooth micro-wear characteristics of east African australopithecine specimens are indistinguishable from those of chimpanzees and orangutans, which are commonly assumed to be frugivorous primates.

However, research on the diets of contemporary primates suggests that micro-wear studies may have limited utility in determining the foods that are actually eaten. For example, insect eating, which can cause distinct micro-wear patterns, would not cause much tooth abrasion in modern baboons, who eat only soft-bodied insects rather than hard-bodied insects. In addition, the diets of current omnivorous primates vary considerably depending on the environments that different groups within a primate species inhabit; if australopithecines were omnivores too, we might expect to find considerable population variation in their tooth micro-wear patterns. Thus, Walker’s description of possible australopithecine diets may need to be expanded to include a much more diverse diet.

It can be inferred from the passage that if studies of tooth micro-wear patterns were conducted on modern baboons, which of the following would most likely be true of the results obtained?

• AThere would be enough abrasion to allow a determination of whether baboons are frugivorous or insectivorous.
• BThe results would suggest that insects constitute the largest part of the baboons’ diet.
• CThe results would reveal that there are no significant differences in tooth micro-wear patterns from one regional baboon population to another.
• DThe results would provide an accurate indication of the absence of some kinds of insects from the baboons' diet.
• EThe results would be unlikely to provide any indication of what inferences about the australopithecine diet can or cannot be drawn from micro-wear studies.
  

OA：D

OG上是说hard 和 soft insect产生的wave会有不同，可是这个点文中没说啊，它只说insect eating, which can cause distinct micro-wear patterns, would not cause much tooth abrasion in modern baboons, who eat only soft-bodied insects rather than hard-bodied insects.

还有OG阅读里面有一句话的翻译，楼主也是不懂


investment in services, like those in production and distribution , must be balanced against other types of investment on the basis of direct, tangible benefits such as cost reduction and increased revenues.

你已经定位了，就是这insect eating, which can cause distinct micro-wear patterns, would not cause much tooth abrasion in modern baboons, who eat only soft-bodied insects rather than hard-bodied insects.
注意加粗部分，表明了这种pattern是属于只吃软体虫子rather than硬虫子的动物的。也就是说，有这种pattern的动物只吃软动虫子，不吃硬虫子。
D说provide an accurate indication of the absence of some kinds of insects from the baboons' diet.这里的absence指的就是硬虫子，因为有这种pattern的动物它们的diet中没有硬虫子
说的有点啰嗦，不知道说明白了没

insect eating,（which can cause distinct micro-wear patterns）, would not cause much tooth abrasion in modern baboons, (who eat only soft-bodied insects rather than hard-bodied insects.)
这难道不是说会引起明显pattern的吃虫子习惯不会导致那些只吃软虫子的牙齿损伤这个意思吗？橙色那一块修饰insect eating，后面蓝色那一块修饰baboons。所以那个parttern应该只是修饰insect eating吧？虽然知道这样咬文嚼字在考场上用不到，但还是想搞清楚一些

insect eating would not cause much tooth abrasion in modern baboons
句中主干就是这种insect eating 不会造成狒狒产生太多牙齿磨损。什么样的insect eating呢，你已经说可，会造成pattern的，什么样的狒狒呢，只吃软虫子不吃硬虫子的狒狒。
原文意思：insect eating 可以造成pattern，insect eating的狒狒不吃硬虫子。
问infer，D说，有这种pattern的狒狒都不吃某种东西（这里是硬虫子）
就是把insect eating这个例子拿掉了。只要有会产生pattern的东西（就是insect eating，他没原话说出来，当年ETS就喜欢这么干）的狒狒都不吃某种东西（比如硬虫子）。
想想原文的逻辑结构，应该会方便理解一些

我想请问一下下面这题~
4.        The passage suggests which of the following about the micro-wear patterns found on the teeth of omnivorous primates?
推断题，问在杂食灵长类动物的牙齿磨损情况，定位找改写。
A.The patterns provide information about what kinds of foods are not eaten by the particular species of primate, but not about the foods actually eaten.
B.The patterns of various primate species living in the same environment resemble one another.
C.The patterns may not provide information about the extent to which a particular species’ diet includes seeds.
D.The patterns provide more information about these primates’ diet than do the tooth micro-wear patterns of primates who are frugivores.
E.The patterns may differ among groups within a species depending on the  environment within which a particular group lives.

答案是D，不过B选项为什么不对呢，说会根据环境不同而不同，那么环境相同不就会相似吗~
