Thank you, thank you Ron. I am talking about OG problems and the explanation provided by OG.
I run into many situations that OG explanations seem inconsistent to me--to be more accurate, I guess that might be one reason I thought sth wrong in the correct AC? Maybe these are the 'meaning' thing you pointed out? Here are some examples:
*************
OG10, SC#37, there is no 'and' btw the 'last' two items of a list in the correct AC? I thought the 'and' is required?
OG12, SC#3, MGMAT said(p210) this structure is wordy: 'it is...that...', I eliminated the correct AC exactly based on my memory on that rule. Instead I chose (C), but then OG says (C) is 'wordy and awkward' (no other fault though). So then why one kind of 'awkward' is acceptable, the other one leads to a wrong AC?
OG12, SC#14, I now understood that the correct AC is the best one and why (C) is wrong, but OG's explanation on (C) confused me cause I thought (C) was a case of 'omission of Although clause', isn't it?
OG12, #46, grammatically, I thought in the correct AC there should be an article 'the' in front of the 'construction and decoration'
OG12, SC#26, I remember there are several places when OG explains a wrong AC, it says 'which' didn't refer to the immediate noun before it, but here is the exact situation in the correct AC?
OG12, SC#50, the correct AC uses 'instead' while in the explanation for some other questions OG mentioned that ' 'instead' is awkward'; also in Q50, the explanation on (D) is that "recession must be followed by 'that' ", but I remember that the relative clause desc the obj can omit 'that', 'which' thing.
**************
For most of these problems, I now understood why the correct AC is the best one. But I hope, from the list above, you might come up insight on where I went wrong. Are the things above solid grammar, or belong to the vague area of meaning/concision in the GMC? Do I just memorize that situation like above can be very flexible? Should I read that much into OG's explanation? (*) --- Very often when the correct AC doesn't stand out from other distinguishing point and I have to rely and struggle on the confusing thing desc'd above, I can end up with wrong AC after spending lot of time. Or even worse, I simply eliminated the correct AC due to some explanations I remembered from OG. Such kind of confusion also costs me tons of hours in my study. In any way, telling a 'meaning' problem apart from a grammar one seems hard for me.
(*) Actually along this line I have a question on CR explanation as well--occasionally, I don't feel that OG's explanation on the wrong AC is to the right point. I mean the wrong one is wrong for some reason other than what OG points out. Am I right, or in such case I should go back and try hardER to understand OG's point?
Thank you!!
