In DS, suppose the question stem says "Are the lines perpendicular to each other?"
1) Do we have to evaluate for "Yes/No", or
2) Do we evaluate for only a successful condition?
I have been struggling with it for a while now. Could some of you please elaborate on this? I started with option 1) mindset but OGs questions were coming incorrect as they seem to follow the no 2) strategy. Now I find the the other materials --like some of the 800 questions are following 1).
Please clarify.

If you can answer the question concretely with either a yes or no, then the statement is sufficient. Because answering "no" to a question answers it. The only way you rule a statement insufficient is if you can't figure out with certainty if it's a yes or no.
In your example suppose the first statement proves to you that the line is NOT perpendicular for sure, then the statement is statement. However after you analyze the statement if you find out that the statement isn't concrete. Or if it leads to two cases where the answer can be yes or no depending on other criteria it's insufficient. To give an example, if the analysis says something like, "It's perpendicular if this angle is 60 degrees" but you have no idea whether that angle is 60 then it's insufficient.
Hope this helps.
