this question helped me realize why this section is 12hrs long :/

only 6 seconds off target!! I do not know how y'all did the last question, it took me out, but Net Eff. questions just click.

😂 lmaooo i thought I was the only one that noticed this. I try planning my days by 7Sage's recommended time and AP was the only section that actually followed their timeline.

24 seconds faster than the target !! loving AP

LMAOOO i thought i was the only one !! Colin's comments make my day fr

I was caught off guard by this too at first. However, I can appreciate it not being in the foundation lessons because it would have made it more complicated and confusing than it needed to be. As long as you know it's a conclusion, the type of conclusion it is you kinda pick up over time.

I narrowed down this answer choice to B and D, very quickly but it took time to flush out D and why it was wrong. Here is how I did it because I feel like the video didn't do quite a good job of explaining why D is wrong.  (please excuse the errors, I just copied and pasted this from my BR journal section)

First: Drop the assumption that all SA questions need to be mapped because I wasted valuable time trying to map this out instead of strategically thinking through this. 

Second: You have to identify that the conclusion is a comparative claim. Moreover, it is a comparative claim about quantity. Yet we don't know the quantity of the pintip group and balded tip group. So I knew that the answer choice would deal with clarifying this gap. 

Eliminate A, C, and E because all those answer choices do not deal with clarifying the size of the pintips in comparison to the baldtips. 

Third:  Look at D in comparison to B. B only talks about one group, leaving pintips a big question mark. Even if this is true,to reach the conclusion the pintip group would have to be larger or just a big as the baldtip group for the fact that the majority of balded etching tools are not used for engraving tools to not matter anymore. 

So, the answer is B.  (because if this is true, and all of the pin-tips etching tools are used to engrave, the quantities of 'some' for the balded tools are less important. Whatever the number of engraving tools in the sub-group of balded tools, when counted with the pintips, it will always be greater than the non-engraving group.

Further Explanation (just in case for those that like detail)

Try going through each answer choice and asking what will the consequence of this be when interacting with the premises. Will I get the conclusion or not?

We would need B first before the answer choice D matters. Because without B, the pin tool group could very well be only 2 and the bald tip group could be 5. Now the fact that all pin-tips are used for engraving isn't as strong to deliver us to the conclusion. We can reach the opposite version of the conclusion because we can toggle the size arbitrarily. The quantity would have to be the same and only when this is achieved can we continue on and say, Even if this is true.... etc., the premise we have that all pin tips are used for engraving means that even if 'some' only means 1 balded tool is used for engraving, the engraving group will still have more member in the group when comparing the two

thank you for this, because I got it right but took nearly 4 mins :/

Rightt!

By inserting "only", you trigger group 2 indicators, meaning anything following only becomes the necessary condition. "All" is the sufficient condition indicator. So whereas "all" triggers group 1 indicators and holds birds in the sufficient, "only" puts birds in the necessary condition, answering the question of " we don't know if non-birds also migrate south in winter." The use of "only" indicates that birds are the only things that migrate south for the winter. So because the necessary fails, the sufficient fails as well making the statement, "...the monarch butterfly does not migrate south in winter" a valid conclusion. Hope this helps :)
