[讨论]XDF阅读分册与OG阅读出题特征差异？

做完XDF阅读分册与OG阅读的朋友会发现，即使是同一篇阅读，XDF阅读分册里的题要多于OG阅读，而且基本题目差异在细节定位题，如以XDF第12篇“1960S 以后，政府对minority business扶持政策的改变”为例，差异的两道分别是：

5.    Based on information in the passage, which of the following would be indicative of the pragmatism of MESBIC staff members?
I.    A reluctance to invest in minority businesses that show marginal expectations of return on the investments
II.    A desire to invest in minority businesses that produce goods and services likely to be of use to the sponsoring company
III.    A belief that the minority business sector is best served by investing primarily in newly established businesses
(A) I only
(B) III only
(C) I and II only
(D) II and III only
(E) I, II and III

9.    The passage provides information that would answer which of the following questions?
(A) What was the average annual amount, in dollars, of minority business receipts before the SBA strategy was implemented?
(B) What locations are considered to be unfavorable for minority businesses?
(C) What is the current success rate for minority businesses that are capitalized by MESBIC’s?
(D) How has the use of federal funding for minority businesses changed since the 1960’s?
(E) How do minority businesses apply to participate in a MESBIC program?

这两类题在XDF分册里比较典型，往往需要多处细节定位。

我想问的是：
OG没有突出这两类题，是否表明一种出题思路的变化，还是说OG仅仅只是收录的题少些而已，并没有我提到的以上出题差异？

另外，就个人感觉而言，XDF里的题出得要难一些(我指OG里面没有的题)，而且更强调逻辑思维能力。比如：

XDF第10篇讲咖啡因的文章里第2题，整个有点考逻辑的味道：
2.    Which of the following, if true, would most weaken the theory proposed by Snyder et al?
(A) At very low concentrations in the human brain, both caffeine and theophylline tend to have depressive rather than stimulatory effects on human behavior.
(B) The ability of caffeine derivatives at very low concentrations to dislodge adenosine from its receptors in mouse brains correlates well with their ability to stimulate mouse locomotion at these low concentrations.
(C) The concentration of cyclic AMP in target neurons in the human brain that leads to increased neuron firing can be produced by several different phosphodiesterase inhibitors in addition to caffeine.
(D) The concentration of caffeine required to dislodge adenosine from its receptors in the human brain is much greater than the concentration that produces behavioral stimulation in humans.
(E) The concentration of IBMX required to dislodge adenosine from its receptors in mouse brains is much smaller than the concentration that stimulates locomotion in the mouse.

XDF第14篇讲“早期胚胎一分为二”的文章里第9题，也是考的逻辑(类比)：
9.    Which of the following circumstances is most comparable to the impasse biologists encountered in trying to resolve the debate about cell determination (lines 12-18)?
(A) The problems faced by a literary scholar who wishes to use original source materials that are written in an unfamiliar foreign language
(B) The situation of a mathematician who in preparing a proof of a theorem for publication detects a reasoning error in the proof
(C) The difficulties of a space engineer who has to design equipment to function in an environment in which it cannot first be tested
(D) The predicament of a linguist trying to develop a theory of language acquisition when knowledge of the structure of language itself is rudimentary at best
(E) The dilemma confronting a foundation when the funds available to it are sufficient to support one of two equally deserving scientific projects but not both

另外，XDF分册里的态度题、文中某一段的结构题也出得比OG多。
我们一般说OG是宝典，语法我是绝对同意，逻辑也说得过去，但阅读呢？我拿不太准，也就是对XDF里的出题特征有些疑惑。

高手给个答复？谢谢。

应该说XDF的比较接近原来的笔考题，每篇的题目更多一些，所以机考更注重全文结构

对出题特征有疑问的话就到机经区看看真题总结吧，那些最近的考题是最有代表性的
