标题: 求助og diagnostic test CR
求手边有og大神解答。。。我实在找不到diagnostic test的题目文档了。。。

24题 24. The percentage of households with an annual income
of more than $40,000 is higher in Merton County than
in any other county. However, the percentage of
households with an annual income of $60,000 or more
is higher in Sommer County.
If the statements above are true, which of the
following must also be true?
(A) The percentage of households with an annual
income of $80,000 is higher inSommer County
than in Merton County.
(B) Merton County has the second highest
percentage of households with an annual income
of $60,000 or more.
(C) Some households in Merton County have an
annual income between $40,000 and $60,000.
(D) The number of households with an annual
income of morethan $40,000 is greater in
Merton County than in Sommer County.
(E) Average annual household income is higherin
Sommer Countythan in Merton County.
就是household income>40000 那道 D我觉得能推出来啊

假设M都是40000-60000的有十个人 S60000以上的有8个人，符合M>40000最多，S>60000最多这个条件因为M 根本没有60000以上的
但若M40000-60000有8个人，S 60000以上的有十个人，就不符合题目的条件了。所以能推出D中M>40000的人数比S多这个结论啊

还有23题 Motorists in a certain country frequently complain
that traffic congestion is much worse now than it was
20 years ago. No real measure of how much traffic
congestion there was 20 years ago exists, but the
motorists' complaints are almost certainly
unwarranted. The country's highway capacity has
tripled in the last twenty years, thanks to a vigorous
highway construction program, whereas the number
of automobiles registered in the country has
increased by only 75 percent.
Which of the following, if true, most seriously weakens
the argument?
(A) Most automobile travel is local, and the
networks of roads and streets in the country's
settled areas have changed little over the last
20 years.
(B) Gasoline prices are high, and miles traveled per
car per year have not changed much over the
last 20 years.
(C) The country's urban centers have well-developed
public transit systems that carry most of the
people who commute into those centers.
(D) The average age of automobiles registered inthe
country is lower nowthan it was 20 years ago.
(E) Radio stations have long been broadcasting
regular traffic reports that inform motorists
about traffic congestion.
C选项公共交通发展很好带来很多人去市中心，所以堵车现象严重了这个思路不对么？

20题In the past, most children who went sledding in the
winter snow in Verland used wooden sleds with
runners and steering bars. Ten years ago, smooth
plastic sleds became popular; they go faster than
wooden sleds but are harder to steer and slow. The
concern that plastic sleds are more dangerous is
clearly borne out by the fact that the number of
children injured while sledding was much higher last
winter than it was 10 years ago.
Which of the following, if true in Verland, most
seriously undermines the force of the evidence cited?
(A) A few children still use traditional wooden sleds.
(B) Very few children wear any kind of protective
gear, such as helmets, while sledding.
(C) Plastic sleds can be used in a much wider variety
of snow conditions than wooden sleds can.
(D) Most sledding injuries occur when a sled collides
with a tree, a rock, or another sled.
(E) Because the traditional wooden sleds can
carry more than one rider, an accident involving
a wooden sled can result in several children
being injured.

题目的结论是plastic sled 比wood的更危险要是削弱的话可以说plastic 的不危险也可以说 wood的更危险，而E选项我觉得比C选项说的更直接一些啊，直接指出了wood
更危险。

24题，原文中是百分比，D选项中是具体数字，相对数字的数据不能拿来推绝对数字。。

作者: Hgc1943 时间: 2013-8-30 03:33
23题，在我看来C是增强了结论的，因为里面提到了，WELL-devoleped，倾向性应该是公共汽车能解决拥堵问题的，因为一个汽车能装好几十人，一个轿车只能装5个人吧。。

20题的话，根据E选项，得出的结论应该是WOOD SLEDS很危险，E选项根本没有出现跟PLASTIC SLEDS的比较，怎么能得出更危险的结论呢？
