I see there's a few doubts on Q3, Q6 and Q7. While I'm not claiming to be an expert by any stretch of the imagination, I have come to value this forum a lot during my GMAT Prep, and have found contributing to the forum an important part of both my learning, as well as the broader communities. I'll start by touching on question 3 - hope this helps!
A few thoughts on tackling RC in general.
1. I always, always, always - rephrase the passage as I read. I think every sentence or two, I do this unconsciously; it's 'active' reading in practice. Having this reflex and improving your ability to rephrase and simplify a passage is incredibly important in being able to have a general roadmap of the passage as a whole. As you practice this skill, the 'what's the point of the passage?' questions should become very intuitive. It's not easy though and at first it's very easy to read the passage as 'fact, fact, fact' so I encourage you to be super vigilant of how you read. I know it took me a while!
2. For every question, always go back to the passage. Whether the question is specific and asks you to make an inference, or is general and asks you what the overall tone is, it's important to go
back to the passage. The third question of this RC is, in my opinion, a prime example of how you can become easily confused if you do not return to the passage.
3. Always find 4 wrong answers! Like
GMATNinja has emphasized, this needs to become your motto. With every question I do, whether I got the answer right or wrong, whether I found it easy or hard, I go back and ensure that I am able to justify each of answer choices (A) through (E). It's often times easy to say "oh that question was so easy" and look at just the questions that challenged you; however, I've found that scrutinizing each answer choice has reinforced my ability to pick out patterns of typical 'trap' answers.
That said, I'll go into how I was able to answer some of the challenging questions in this set. What is challenging for me, may or may not be for you, but this is just what I found from previous discussions to be of noteworthy mention.

3. It can be inferred from the passage that the author considers labor disruptions to be...
(A) an inevitable problem in a weak national economy
(B) a positive sign of employee concern about a company
(C) a predictor of employee reactions to a company’s offer to sell shares to them
(D) a phenomenon found more often in state-owned industries than in private companies
(E) a deterrence to high performance levels in an industry
Step 1: First thing I do - I go back to the passage. In this case, that is the 2nd paragraph. I already have the general road map of this passage in my head, and I know I'll find my answer here. I look at the opening sentence and see that it states two things that privatization has done: rescue industries/economies, and raise performance in every area within industries/economies. The next sentence lists examples of how performance was improved in various industries.
Quote:
In fact, privatization has not only rescued individual industries and a whole economy headed for disaster, but has also raised the level of performance in every area. At British Airways and British Gas, for example, productivity per employee has risen by 20 percent. At Associated British Ports, labor disruptions common in the 1970s and early 1980s have now virtually disappeared. At British Telecom, there is no longer a waiting list—as there always was before privatization—to have a telephone installed.
Step 2: Find 4 wrong answers - this is not the same as finding 1 right answer! (A) an inevitable problem in a weak national economy -
Nowhere does the passage indicate that the author considers labor disruptions to be inevitable in any economy. That's it. Do not linger on this and think "oh well...it's probably true in weak economies... there probably are more labor disputions in a weak national economy and yea...it's probably inevitable given crappy economic circumstances." Remember that you're working within a 'closed environment' for RC.(B) a positive sign of employee concern about a company -
the author discusses employee concern about a company in the third paragraph when discussing stock ownership and union wage discussions; however, the author does not do so in the context of labor disruptions(C) a predictor of employee reactions to a company’s offer to sell shares to them -
this option claims the author considers labor disruptions to be a reaction to a company's offer to sell them shares... the author does not do this. This option has mashed together concepts from paragraphs 2 and 3 in a nonsensical way(D) a phenomenon found more often in state-owned industries than in private companies -
I think that people are most tempted by this option because it draws on what is a very logical conclusion. Yes, it's probably true that you find this phenomenon - labor disruptions - more often in state-owned industries than in private companies. Unfortunately, drawing on your assumption and bringing your thoughts into what is supposed to be a 'closed and controlled environment' in RC, more often than not leads to wrong answers. The author does not, in any part of paragraph 2 - the relevant portion - indicate that you'd find labor disputes more often in state-owned vs privately-owned companies.
You have to stop yourself before you even get off track and think 'oh well labor unions are probably more common in state-owned operations like Transit Systems, and ugh yes those are definitely very predisposed to labor disruptions. UGH Canada POST!! See, that what I did right there, is allow my thoughts to color RC. Tsk, tsk, a big fat NO NO.(E) a deterrence to high performance levels in an industry -
Bingo. The structure of the sentences in paragraph 2 allow you to infer (i.e. from the given text, make a directly conclusion without making any additional assumptions) that labor disruptions are a deterrence to high performance levels. The first sentence states that privatization has saved industries/economies, and the second gives examples of how specific event have various industries have been saved.
The statement that "Associated British Ports, labor disruptions common in the 70s and 80s have now virtually disappeared", in the context of paragraph 2, allows you to infer that the disappearance of labor disputes improved performance levels, which is a simplified way to saying that the disappearance was "a deterrence to high performance levels in an industry"Hope this helps!
