Which of the following most logically completes the passage?

Using new detection techniques, researchers have found trace amounts of various medicinal substances in lakes and rivers. Taken in large quantities, these substances could have serious health effects, but they are present in quantities far too low to cause any physiological response in people who drink the water or bathe in it. Nevertheless, medical experts contend that eliminating these trace amounts from the water will have public health benefits, since __________.

输血50,verbal悲剧了。直接上狗狗吧

输血
碰到了蛮多狗狗的~LZ慢悠悠滴做完数学还有10分钟

有一道是A到F在数轴上等距排列,E=3^11,F=3^12,问哪个等于(-3^12)

一个书店还是神马地方里有N本书,其中有40本fiction,剩下的nonfiction;有50本硬皮,剩下的软皮。其中硬皮的fiction有30本,问N最少是多少。

一个神马数据XX,假设是population吧,1980年的XX是1990年XX的(83+1/3)%,问XX从1980到1990增长了多少。

DS:xy^2z^3>0? GWD 还是OG的原题来着
1。xz>0
2.yx>0(条件不太确定)

余温LZ做得很开心,但是结果出来就不开心了。裸机和月度都自我感觉良好,应该是愈发出了问题。愈发那一个叫长,都是2满行或者接近2行的,划线几乎都是整句或者大半句,只有1题的划线是5~6的单词的样子,神马OG神马GWD都是骗人的,估计掉了高分库又没做好吧……悲剧就是了,又不是看不懂那种,就是结构超级混乱又长,要花时间做,选了还不一定对,唉

愈发有一道说,A是对XX和YY的第二大威胁,仅次于B。应该是GWD或者OG的原题,或者换了名词但是结构应该是一样的。

月度遇到了恐龙灭绝那个,问题跟这个版本的狗完全不一样~所以大家看一下大概的结构吧,题目还是要自己看
V2  【by: ruoruoiris】

一屏左右的文章,两段,开头就讲了K-T事件,就是恐龙灭绝的事件(第一句搞亮了)很多scientists认为是小行星撞击造成恐龙灭绝,讲了一堆证据和原因,提到fossils里面有大量动物灭绝的证据(有题)。然后有人跳出来说,不对,小行星撞击不是直接原因,撞击后地球发生变化,慢慢产生什么气体还是物质,导致大气不正常,global warm, 然后很多动植物才慢慢死掉。。。
第二段就说有人研究认为是volcanic eruption造成的,行星撞击造成大量火山喷发,不仅火山灰掩埋了一些动植物,更是由于火山喷发造成大气温度的升高,慢慢使很多动植物死亡。(有题)后面的就不咋记得了。。。。。

这个说得蛮清楚了,也大概就是那样子。

还有一篇小行星的,早上出门前刚看到更新,特此感谢狗狗主人!
Yet the rubble-pile hypothesis is conceptually troublesome. The material strength of an asteroid is nearly zero, and gravity is so low you are tempted to neglect that, too. What’s left? The truth is that neither strength nor gravity can be ignored. Paltry though it may be, gravity binds a rubble pile together. And anyone who builds sand castles knows that even loose debris can cohere. Oft-ignored details of motion begin to matter: sliding friction, chemical bonding, damping of kinetic energy, electrostatic attraction and so on. (In fact, charged particles from the sun can cause dust at the surface to levitate.) We are just beginning to fathom the subtle interplay
of these minuscule forces.

The size of an asteroid should determine which force dominates. One indication is the observed pattern of asteroidal rotation rates. Some collisions cause an asteroid to spin faster; others slow it down. If asteroids are monolithic rocks undergoing random collisions, a graph of their rotation rates should show a bell-shaped distribution with a statistical “tail” of very fast rotators. If nearly all asteroids are rubble piles, however, this tail would be missing, because any rubble pile spinning faster than once every two or three hours (depending on its bulk density) would fly apart. Alan Harris of the Jet Propulsion Laboratory in Pasadena, Calif., Petr
Pravec of the Academy of Sciences of the Czech Republic in Prague and their colleagues have discovered that all but five observed asteroids obey a strict rotation limit [see illustration on page 48]. The exceptions are all smaller than about 150 meters in diameter, with an abrupt cutoff for asteroids larger than about 200 meters.

The evident conclusion—that asteroids larger than 200 meters across are multicomponent structures or rubble piles—agrees with recent computer
modeling of collisions, which also finds a transition at that diameter. A collision can blast a large asteroid to bits, but those bits will usually be moving slower than their mutual escape velocity (which, as a rule of thumb, is about one meter per second, per kilometer of radius). Over several hours, gravity will reassemble all but the fastest pieces into a rubble pile [see illustration above]. Because collisions among asteroids are relatively frequent, most large bodies have already
suffered this fate. Conversely, most small asteroids should be monolithic, because impact fragments easily escape their feeble gravity.

LZ做到的只有后2段,一个问文章的主要目的,一个问文章的结构,一个问削弱最后一段的第一句里的evident的。还有一个,绕了一大圈,问那些旋转的速度快得足以让行星fly apart的小行星一定是以下哪一种(囧,表达不能)。LZ的思路是这样的:If nearly all asteroids are rubble piles, however, this tail would be missing, because any rubble pile spinning faster than once every two or three hours (depending on its bulk density) would fly apart.因为行星们都不能旋转太快,否则他们会fly apart,又Alan Harris of the Jet Propulsion Laboratory in Pasadena, Calif., Petr Pravec of the Academy of Sciences of the Czech Republic in Prague and their colleagues have discovered that all but five observed asteroids obey a strict rotation limit。 The exceptions are all smaller than about 150 meters in diameter, with an abrupt cutoff for asteroids larger than about 200 meters.
所以,那些旋转得那么快,又不会fly apart的,就是那些BUT FIVE,既那些exceptions了,所以选smaller than about 150 meters in diameter
应该没错吧,还是请N人确定一下。

一个月度不记得鸟……还有一个,第一段讲说business都是出于自己的利益而不是公众的利益去影响政府对于regulation的决策??制定??反正就是这个意思,第二段就讲了一个特例,说一个神马train神马东东的不知道干嘛……郁闷,看的似懂非懂的。有一个问题问削弱第一段的论点的。

裸机
有戒烟药的变体,就是讲N跟S两个戒烟药,一个prescription一个nonprescription,然后结论是说N销量/revenue(不记得了,反正其中之一)的增长是at the expense of S的销量/revenue,问加强。

有一个说大部分滴美国学生在课堂上抄的笔记内容只有老师的板书的一半左右,然后有一个不晓得神马公司还是神马机构就会去每一堂课帮你抄笔记,这样你就不会漏了任何笔记滴内容,问下面那个一定是正确的,有2个很接近的,说用了这家东东的笔记的学生在笔记方面比没有用的学生有优势,另一个说这家东东的笔记的学生在笔记方面比~~any不知道神马学生有优势,LZ纠结了一下选了前一个

还有一个说,在某湖监测到了一个medical神马东东的存在,这种东东对人体有害,但是它的含量在一个很低的不会影响喝这些水的人的健康的数值。however,消除这个东东还是有必要的,因为消除这个东东对人的健康还是有好处的,问加强。LZ选了一个XX bacteria expose to 那个medical东东会变得对那个东东有抗体/抵抗力?= =LZ表达不能,大家自己体会。。。

坐稳
一个说L钢琴制造商以生产高质量昂贵的钢琴出名,但是最近L的revenue下降了。另一家乐器制造商A在引进了电子琴生产线之后,revenue增加,所以L也应该引进电子琴生产线in a variety of ranges,这样就能增加revenue甚至outsell A公司。又说customer会accept这些电子琴,因为customer会associate with L家的prestigious XX(品牌)??

一个说要求全国公民都参加一定的社会服务不仅有利于国家且有利于个人。

想到再补充吧~~~
