I got the idea that the most important step of nailing RC is to understand the structure and the main idea(the author's attitude) of the whole passage.
During the first reading, read ONLY views instead of examples.
However, as gmat RC is getting harder, sometimes it is really difficult for me to make a decision about which sentence to read, which not! Since the description has to be understood in order to understand somebody's views.

I'd make a examples:
In recent years, Western business managers have been heeding the exhortations of business journalists and academics to move their companies toward long-term, collaborative "strategic partnerships" with their external business partners(e.g., suppliers). The experts advice comes as a natural reaction to numerous studies conducted during the past decade that compared Japanese production and supply practices with those of the rest of the world. The link between the success of a certain well-known Japanese automaker and its effective management of its suppliers, for example, has led to an unquestioning belief within Western management circles in the value of strategic partnerships. Indeed, in the automobile sector all three United States manufacturers and most of their European competitors have launched programs to reduce their total number of suppliers and move toward having strategic partnerships with a few.

However, new research concerning supplier relationships in various industries demonstrates that the widespread assumption of Western managers and business consultants that Japanese firms manage their suppliers primarily through strategic partnerships is unjustified. Not only do Japanese firms appear to conduct a far smaller proportion of their business through strategic partnerships than is commonly believed, but they also make extensive use of market-exchange relationships, in which either party can turn to the marketplace and shift to different business partners at will, a practice usually associated with Western manufacturers.

Which of the following is cited in the passage as evidence supporting the author`s claim about what the new research referred to in line 20(see highlighted text) demonstrates?(first reading this question, what the hell is ABCDE talking about...none of them is similar to what I understand..)
A The belief within Western management circles regarding the extent to which Japanese firms rely on strategic partnerships
B The surprising number of European and United States businesses that have strategic partnerships with their suppliers
C The response of Western automobile manufacturers to the advice that they adopt strategic partnerships with their suppliers
D The prevalence of "market‐exchange" relationships between Japanese firms and their suppliers
E The success of a particular Japanese automobile manufacturer that favors strategic partnerships with its suppliers

Although it is clear that a view has been questioned from the big "HOWEVER", it is still difficult for me to choose what to read for the first time. Also, some description is vague and indirect, it takes me a lot of time to understand what the author is trying to talk about.

So, I guess I really should understand each views presented in the article during my first time reading! Even if I couldn't understand the sentence for the first time, I should repeat reading it until I get it and move on to next...
(I realized just moving my eyes from line to line and getting nothing in my mind are really annoying, I couldn't barely understand the DETAILED QUESTIONS)

Also, I really have a Nemo's memory,
For some really clarified structure, such as:
paragraph1
A view, why the view is held by many people, however, the view has two limitations.. There are two opposing views about how to solve the limitations
paragraph2
A new research justifies that one of the opposing view is correct.. how the study is conducted...

OK, I got the structure, and I understand all the first paragraph is talking about(everything!!)
but I could not remember which two limitations are...When I saw a question about it...I have to go back and find and read again..
However, if I DO NOT understand what the two opposing views are talking about, I could not understand the next paragraph is talking about right??
So... I really do not know how to solve it

For a non-native speaker like me, it is already difficult to understand the passage(so many long and complex sentences) in a short time, there is a huge GAP between understanding the passage and getting right on questions!!!

Sometimes I wonder, what the hell is the question talking about? or what the hell do those ABCDE mean(sometimes they look long and complex)...
