I am a bit confused on how come some Strengthen questions require us to use the Assumption skills from PSA and SA questions. However, there are also some strengthen questions that did not require us to draw out the conditional chains and only requires us to affirm paraphrased "assumptions".
Is it only for questions that have "principle" that we automatically should treat them as PSA or SA questions? Or is it safe to use the PSA and SA method for ALL Strengthen questions?
Any insight on this matter would be greatly appreciated!
