逻辑有一道题，请慎重参考答案，介于小的verbal就60%正确率
有个洗发液广告，某个偏远地区的土著用某个植物来洗头，我们现在也用这个植物来做洗发液。当地土著头发长得特别好，所以我们的洗发液也能防止脱发。 问weaken
排除剩下的两个选项一个是：因为当地人最先选择这种植物，所以他们的使用一定没有interruption。 2是当地人不用这种植物的话头发会不好。选了第二个。
阅读有三篇文章主题大概记得
1. galaxy这道，一下摘自GWD。基本内容是一样的，貌似还多了一段说观测问题。就是这个黑洞路过星星，这个星星会变得不可见，但是其他周围稳定的星星光线会突然变亮。问了文章主旨，问了第二段的作用。还提到一种用大写字母表示的物质，是科学家认为黑洞质量的组成物质。问了这种物质的细节。
in addition to conventional galaxies, the universe contains very dim galaxies that untilrecently went unnoticed by astronomers. Possibly as numerous as conventional galaxies, these galaxies have the same general shape and even the same approximate number of stars as a common type of conventional galaxy, the spiral, but tend to be much larger. Because these galaxies' mass is spread out over larger areas, they have far fewer stars per unit volume than do conventional galaxies. Apparently these low-surface-brightness galaxies, as they are called, take much longer than conventional galaxies to condense their primordial gas and convert it to stars—that is, they evolve much more slowly.
These galaxies may constitute an answer to the long-standing puzzle of the missing baryonic mass in the universe. Baryons—subatomic particles that are generally protons or neutrons—are the source of stellar, and therefore galactic, luminosity, and so their numbers can be estimated based on how luminous galaxies are. However, the amount of helium in the universe, as measured by spectroscopy, suggests that there are far more baryons in the universe than estimates based on galactic luminosity indicate. Astronomers have long speculated that the missing baryonic mass might eventually be discovered in intergalactic space or as some large population of galaxies that are difficult to detect.
2. 女性就业率和缩短收入差距之间的关系
首先说一些人认为增加职位对女性的需求就可以让更多女人上班从而缩短男女之间收入不平等问题。然而这些职位其实之前就面向女性并且工资很低，所以其实是加大了收入差距。
第二段具体解释为什么，职位需求，女性劳动力供给之间的关系。第三段说了可行的方法，就是高教育的女性进入高层职位，以及降低低技术含量职位的男人的工资，这样收入才能平等。文章不难懂
3. 地球地心结构
这个名词太多了不懂，好像说地核是铁的，然后上面还有一个层A，好像是液体的。一般科学家认为这两个层之间有明确分界线，但是其实还有一层B。这B层的特征是不会浮到A层上面因为他们密度大，温度好像有3000°。密度大是因为包含铁元素，上面接A下面接地心这样子。题目问了3000°是什么作用，为什么不会浮到A上面之类的细节题。
