If the Trigger uses 'either or,' what is the appropriate reasoning step?

• A. Do not branch
• B. Branch
• C. Swap the order of options
• D. Assume exclusivity

Answer: (B)

When you see the cue “either or,” you split the problem into two separate paths and analyze each possibility. This is case analysis: assume the first option is true and work out its consequences, then assume the second option is true and do the same. This approach ensures you explore all viable routes and don’t miss a valid solution. Not branching would ignore one possibility, swapping the order of options doesn’t change the underlying logic, and assuming exclusivity adds an extra constraint that isn’t given unless the problem states it. So, the right step is to branch and examine both possibilities.
