og149 和 og239 中的 as...as, or/and more than

OG149在(as fast as, and in some parts even faster than, those)中为什么要用and，不是习惯用法是or吗？

而且在og239的解释虽然说as many as, or more than是idiomatic的，为什么在这里又是wordy的了，

149. Last year, land values in most parts of the pinelands rose almost so fast, and in some parts even faster than what they did outside the pinelands.
A. so fast, and in some parts even faster than what they did
B. so fast, and in some parts even faster than, those
C. as fast, and in some parts even faster than, those
D. as fast as, and in some parts even faster than, those
E. as fast as, and in some parts even faster than what they did

The properly completed sentence here must (1) use the proper form of the comparative conjunction, as fast as; (2) enclose the parenthetical statement and... even faster than in commas; and (3) preserve parallel structure, clarity of reference, and economy by using those to substitute for land values in the completed comparison. D, the best choice, does all these things correctly. A and B use so unidiomatically in place of as. A and E omit the comma needed after than and use the confusing and unparallel what they did instead of those. C omits the second as needed in the comparative conjunction as fast as.

239. Organized in 1966 by the Fish and Wildlife Service, the Breeding Bird Survey uses annual roadside counts along established routes for monitoring of population changes of as many as, or of more than 250 bird species, including 180 songbirds.
A. for monitoring of population changes of as many as, or of
B. to monitor population changes of as many, or
C. to monitor changes in the populations of
D. that monitors population changes of
E. that monitors changes in populations of as many as, or

C is the best choice. The phrase to monitor changes is idiomatic as a statement of purpose ([in order] to monitor), and the intended meaning is expressed concisely and accurately. Neither A nor B produces the idiomatic phrase "... as many as, or more than, 250 ..."--a phrase that would be needlessly wordy here. Also, for monitoring of in A is less concise and idiomatic than to monitor, and population changes in B is less precise than changes in population. In D and E, the pronoun that has no singular noun (required by the verb monitors) to which it can logically or grammatically refer. Survey already has its verb in uses, and no other noun can perform the action of monitors.

比较的范围不一样，请注意in some parts的含义。所以不应该是"或者"的含义。

and表示"和"，"并且"，or表示"或者"。应该从词语的具体含义去理解，不是去记住习惯用法。

谢谢rhod。

那么og239中wordy的问题有答案吗？

这个问题我也曾经想过.

我认为一来149的选项都是这样, 而来in most parts和and in some parts 说明了指的不同对象.

我想可能是说动词uses的主语在这里是Breeding Bird Survey，所以monitors作为动词在句中没有其他名词作它的主语，也就是说在D和E中monitors都缺少自己的主语

语法错误是corrective error, 改变原意也是corrective error. Corrective error里没有priority之说

个人认为:       population changes of more than 250 bird species  既可以指这两百多种鸟总数量的变化,也可以是这两百多种鸟各自种群的数量变化.  有歧义

而changes in populations of more than 250 bird species 就仅仅只能表示各自种群的数量变化.   没有了歧义

所以OG说:Changes in the populations of is clearer than population changes of.

大家认为是这样的吗?考证中...
