关于月球sample的寂静整理

原文重要信息
The strange shape tells a tale of violence: It results from the welding of rock, mineral and glass by the heat of micrometeoroid impacts.为了研究科学家设计了月球车，但是有问题，因为研究需要moon dust 来进行模拟实验进行测试
Until the Apollo astronauts brought lunar soil samples to Earth during 1969-72, the belief was that the Moon's dry, airless environment left the soil largely undisturbed. Reality is much harsher.
The lunar surface is exposed to solar wind and constantly pounded by micrometeorites暴露在太阳风下，而且不断的被微小陨石冲撞These processes form the "regolith" covering the Moon's surface. 形成了（第2题）a complex material comprising "sharp, abrasive（粗糙）, interlocking fragile glass shards（催的玻璃碎片） and fragments," （第五题）It grinds machinery and seals, and damages human lungs. Dust was everywhere and impossible to brush off. All the lunar astronauts had lung reactions to this dust
The Apollo specimens are America's Crown Jewels and （第三题）are doled out in ultra-small samples to scientists who can demonstrate that nothing else will do for high-value experiments.只少量发放给那些能够做很高价值的科学试验的科学家
因为人们对月球开发的兴趣增加，月球模拟就需要了，这使得一种来种AZ的火山灰烬替代品JSC-1A非常流行，他们分成三类（1吨粉状，14吨合适的颗粒，1吨晶状）
MSFC is developing three new simulants. Two will represent mare and polar highlands regions. A third will represent the glassy, sharp, jagged edges of regolithf(风化层) that test the best of hardware and humans.（第八题） But matching every location on the Moon would require large numbers of small, unique, expensive batches.
For example, the new mare simulant will be enriched with ilmenite, a crystalline iron-titanium oxide. （第四题）Source materials used to produce the three simulants will potentially come from locations as diverse as Montana, Arizona, Virginia, Florida, Hawaii, and even some international sites.
问题：
1、    主旨题：选择的是explain context（介绍解释说明）
2、    问这个agglutinates有什么特点。 。我好像选的是被GLASS包围的那一项。 。还有什么IRON含量很高，或者是来自regolith。
3、    从月球上取回来的sample 我选的是他们只对那些研究AISm之类的一个项目的科学家available
4、    有问题问到模拟器中物质的问题，我选这种物质不是所有的都是来自美国的选项
5、    问说如果不是宇航员上月球而是用机器人，那么下面那个是正确的：基本确认，选择说如果机器人能够避免月球表面的对metal的腐蚀那么这个计画就是顺利的。
6、    问关于那个lunar sample的问以下哪个是正确的？我选的是那个lunar sample 几乎包含了major 月球的成分，还有答案是说sample里有月球上带来的火山岩，这是错的，因为原文指明了此火山岩是从在Arizona in US 那里拿来的
7、    infer题：问可以从lunar带回来的sample中知道什么，大概是选科学家只有运用这种simulate才能够进行试验。
8、    第三段US在Arizona用火山岩仿照lunar rock。只仿造3种最基本的--有题，问原因，原因是造所有的成本太高。
