虽然GRE单词的考察点大量集中在填空题上，但是阅读部分的很多题目也会考查学生对词汇的理解，这里的词汇不仅仅是我们理解上的难词，而且还会涉及“熟词僻义”和语义准确度。下面要和大家分享的就是GRE阅读词汇考查点——熟词僻义。
An influential early view held that ecosystems contain niches for a limited number of species and that competition for resources among species—whether native or nonnative invading ones—determines ecosystems’ species composition<这句话看似很长，但是通过“结构性阅读法”，我们可以将这句话浓缩成competition determines ecosystems’ species composition，即物种间的竞争决定了生态系统中的物种构成——早期的一种观点>. However, factors other than competition often help explain invading species’ success. <紧接着开始转折，提出除了竞争，还有其他的因素也能解释入侵物种的成功繁殖——反驳上文的观点>For example, the American grey squirrel, often cited as a classic example of competitively superior invading species, was introduced in England in 1876 and now thrives, while the native red squirrel population has declined. <举例，其目的是为了进一步证明前面的counterview>Although scientists have found gray squirrels to be more efficient foragers than red ones, they also note that even before the gray squirrel’s arrival, Britain’s red squirrel populations had a periodic tendency to die out, only to be subsequently reintroduced. <这里是一个很有意思的让步具句考点：虽然和红松鼠比较起来，灰松鼠觅食效率更高（这里的信息其实是符合首句话观点的，因为觅食效率高也是竞争力强的一种表现），但是红松鼠容易周期性灭绝（在这里，作者进一步证明会有其他因素解释入侵物种的繁殖>Furthermore, many gray squirrels are silent carriers of a disease fatal to red squirrels. <与上文是递进关系，强调灰松鼠身上带有的疾病对当地的红松鼠来说是致命的——说明竞争不是仅有的影响因素>
It can be inferred that the author of the passage mentions the efficiency with which gray squirrels forage primarily in order to
A. identify a factor that explains a certain phenomenon
B. call attention to an inconsistency in a particular theory
C. suggest that competition cannot be the factor responsible for a particular outcome
D. acknowledge a fact that appears to support a view that the author intends to qualify
E. cite evidence that is not consistent with an early influential view about species competition
这里的细节目的题是我们上文读到的让步句考点，跟我们上文的剖析，让步句的目的其实是支持了首句的说法，即竞争会影响物种的繁殖。
D选项中的“qualify”指的是“限定”，而非“证明…合格”这一意思。该句意思是承认一个事实，这个事实支持了作者想要削弱的观点。
因此，这道题应该选D。
