said 2 things: 1. there were about a million copies. 2. they expected piracy to increase.
D：If the above statement is used within a statement in past, then each verb moves one step back (present becomes simple past, simple past becomes past perfect, and future becomes conditional). In the above sentence, the verb "become" is in simple present, and hence when used within a statement in simple past, simple present "become" becomes simple past "became".

先看懂句子想说啥再做题的重要性

once maximum tunneling time is reached, tunneling speed will increase without limit as barrier thickness increases. 漏看了no

most small asteroids should be monolithic, 想太多了，我以为原文这样写的话，B选项will be会显得太绝对，第一个就给排除了。。。

If asteroids are rubble piles,however, the tail representing the very fast rotators would be missing,because any loose aggregate spinning faster than once every few hours would fly apart. 如果比几小时转一次的速度快，就会飞走。所以rubble piles不会飞走 ➡️ 速度要小于几小时一次

both Burckhardt and Kelly made on the basis of their observations about upper-class Italian women.

Jacob Burckhardt's view that Renaissance European women "stood on a footing of perfect equality" with Renaissance men has been repeatedly cited by feminist scholars as a prelude to their presentation of rich historical evidence of women's inequality.
没有理解透彻。 很多女权主义学者引用B的观点，作为大量表现女性不平等历史证据的序曲。➡️ 女权学者觉得不平等，B觉得平等 ➡️ 女权学者想反驳B

错选C
Many recent works by these scholars stress the ways in which differences among Renaissance women—especially in terms of social status and religion—work to complicate the kinds of generalizations both Burckhardt and Kelly made on the basis of their observations about upper-class Italian women.

If early judicial decisions were prejudiced against patentees, one might expect that subsequent courts—allegedly more supportive of patent rights—would reject the former legal precedents.
在说引用pre-1830那句话之前，作者说，如果司法决定改变了态度，对申请专利的人更支持了的话，就会否定1830前的那些司法例子。 但是pre-1830大量引用，说明没有改变态度。

（1） 不充分
（2）不知道在y的截距大小，不充分
（1）+（2）设在 Line n: （0，y1) Line p: (0,y2) y1>y2
Line n: k1= y1-1/ 0-5-->k1=y1-1/-5
Line p: k2= y2-1/ 0-5-->k2=y2-1/-5
y1-1>y2-1--> y1-1/-5

p^2q=5的倍数。所以可以是p为5 也可能q为5.但是要一定成立的话一定要是p^2q^2.因为这样才是must be 25的倍数
题目的问法可以有两种，一种是must be ，一种是could be。这道题问的是must be 的话，就必须排除所有的不可能性
p^2q=5的倍数。那么可以是p=5，q=1.也可以是p=1，q=5.
A选项，p=1，q=5，A选项不成立
B选项，p=5，q=1，B选项不成立
C选项，p=5，q=1.或p=1，q=5.都不成立
E选项，p=1，q=5不成立
D选项，当p=5，q=1.或p=1，q=5.都成立

其实这篇文章主要在讲AFL的立场，立场的exception及其后来立场的转变

文中提到了两种方案，应该集中看题目问的那种的解释，不要想着另外一种

第三个为什么不是verbal啊

奇怪，b的谓语动词是什么？？主句没有谓语啊，全是从句啊

选了E ...... 想说他在每个城市都经过过冬天，不就说明不是一年四季轮个换地儿吗

In Country X's last election, the Reform Party beat its main opponent, the Conservative Party, although pollsters, employing in-person interviews shortly before the vote, had projected a Conservative Party victory.
读题时没有读懂这句话。

比较结构同时要求平行

主谓宾成分具全的比较句，有两种情况：1）宾语的比较；2）主语的比较。在GMAT考试当中， 如果遇到主语比较的情况，一般要求第二个句子补出系动词或助动词，以避免歧义。 如：I eat apple faster than you do. 该句为主语之间的比较，句子中的do是不可以省略的。因为" 如果去掉do，则形成宾语比较句，apple和you进行比较，产生我吃苹果比吃你快的逻辑错误。 但是在只有主谓，没有宾语的句子中，由于没有宾语，所以不会产生上述歧义，所以不需要补充 系动词/助动词。如：I earn more than you.不需要补充do。如果补充了do，反而会构成罗嗦的错误。
