I had 4/5 wrong in original and 5/5 right in BR. RC you have to pick and go, like JY says while decide which AC is right your timer goes down. Go with your gut because most of the time you are right. I find that if i am talking a long time, I flag and move on. 

I was between A and D. I did not look the As-told-to, but i knew it needed to have an oral component to the answer because that is what the author was describing throughout the entire paragraph. Either that or hand gestures as described in the second paragraph. Anyway i was down between A and E and A had the artifacts which I felt odd because we discussed that in the third paragraph, but never into autobiography mentioned in the first paragraph. That made me eliminate A and choose e 

For me I think the highlight for me is that this question helps not the conlusion per se but the REASONING. I felt that the first sentence on reducing accident rate had a limited role on the argument and E justifies its role by displaying if we have something causing less accident then we should implement it. This helps the REASONING more

The question I got right, but it is not only structure but also words that matter, C shows us that the options are both available to us which we need a binary cut in our AC

First time with the passage and I got all questions right. I was mad confused on this passage, but I am happy I won

Not impossible but as a key thumb you always want your pt average to be hovering around the score you want

I skipped thank god, but I understand it now. I choose D but I like AC A, because we assume that the groups had no diffence that would mask the benefits. .This is how I thought of it, in numbers (which represents if V C had an effect)

The stimulus says that both groups has 50 percent of acne.

AC A shows us that both groups did not have an equal footing of acne.

If VC group has 100 percent acene, and then placebo group had 50 percent acene, if the VC group recieved acene, and now they are down to 50 percent (aka no difference in both groups acene), then yeah the VC has an affect on acene.

Control groups does not imply both groups have no differences.

Simple answers are the best one. I choose B then switched to C and felt the biggest regret. But C and B i felt were the same. Until the structure. I seen post saying that for X, Y indicates premise and conclusion, but even if this rule is true, C is not true.

The For STATES, FOR EVEN THOUGH more small modern apartments than are large V apartments, a high proportion of large V than of small modern apartments have FB.

Essentially the even though is not the premise because it is a concession. I assume it was and that is what made me choose C. But technically removing the sentence even though gives us the premise,

For a high proportion of large V than small apartment have FB (FOR Y).

These sneaky test makers.

I am happy I got this one right before Nov exam. For me after identifying the logical gap, I tend to go to AC E and then work upwards. I do not like going to each AC from A to E because sometimes it feels too slow especially once you understand the stimulus. Once I saw E I felt it was very overpowered and would defintely help our argument
