I have a question regarding the missing links when removing a premise and what would suffice for validity:
P(1): A B
P(2): B C
P(3): C D
C(1): A D
If we remove premise (1), are these all the missing links:
Not B Not A
Further, for a weaken question, would we need to find an answer choice that A or B could likely not occur, or perhaps that B is likely to occur only if A cannot occur.
Also, for a strengthen, under the same pre-tense, find an answer choice that A or B is likely to occur, or perhaps that A's occurrence is unlikely even when B's occurrence is unlikely.
Finally, for an assumption, to defend the argument, we need to find an answer choice that, I could use some help with this one.
Thanks, I must master this test, I appreciate your time.
