[MdAbuAsad]

Hi Ron,
An argument/counterargument structure might look something like this:

Nicole believes that merging the two divisions will be the best way to improve our company's overall profitability, because the cultures of the two divisions are very similar. However, Nicole is mistaken. Merging the divisions would lead to resentment among employees, as well as redundant personnel and processes.
Which of the following, if true, would undermine the author's claim that Nicole is incorrect in her belief?

For a confusing question such as this, it is even more important to take notes in an organized fashion. Students who have a confident, robust approach to diagramming will be much better •prepared to handle the intricacies of argument/counterargument questions than students who rely only on their short-term memories. The first step in attacking this question is to identify the conclusion from the point of view of the AUTHOR. In this case, the author of the argument believes that merging the two divisions is NOT the best way to improve overall profitability. Next, note the counter-claim, as well as its proponent. The counter-claim is the belief that merging the two divisions IS the best way to improve overall profitability. This belief is held by Nicole. Often, the best way to keep various claims straight is to associate them with their advocates. Finally, create a modified T-diagram. Extend the central column upward, splitting the area for the conclusion into two sides. Put the author's position on the left side and the counterclaim on the right side. Then fill in the pro's and con's of the author's argument as usual.

Merge is not best
pln for prof
-------------------------
merge = best
pln for prof
Empl resent
Redund ppl and proc
Similar cultures
The advantage of this method is that it is easy to see the dual role of any piece of evidence. The evidence FOR the author's claim is also opposed to the counter-claim. Likewise, evidence AGAINST the author's claim also supports the counter-claim.
See The Official Guide, 12th Edition Question #45 for an example of an argument/counterargument
structure.

This explanation helps us about to detect an argument/counterargument types question but did not finally say how to solve this types of problems after taking note. With taking notes how to solve this types of problem?
Thanks...

we can't answer questions about OG problems on this forum.

in general, you shouldn't have to take notes for CR problems. you should only consider taking notes if you genuinely can't follow the passage otherwise.
...otherwise, you should just process the passage LIKE A CONVERSATION.

in a normal conversation, you'll always know WHY people are saying things -- even if you don't necessarily understand all the facts/specifics themselves.
...and, you would never think to "take notes" on an ordinary conversation. (at least i hope you wouldn't.)
try to process these in the same way.
