ISO 27000 Foundation Certification question I keep getting wrong on ISO practice tests

There's a category of question on my ISO 27000 Foundation Certification practice tests that I'm consistently missing and I can't figure out what I'm misunderstanding.

The questions are about ISO 27000 Foundation Certification. Here's the type of question that trips me up: they give me a scenario and ask what the right action is, and I usually narrow it down to 2 answers — then pick the wrong one.

I think my issue is I'm applying the general rule but not accounting for the exception. Can anyone point me to a good explanation of when the standard rule doesn't apply for ISO 27000 Foundation Certification?

I've looked at "iso 27000 foundation" study materials but they explain the concept at the surface level. I need the deeper "why" behind it.

Any specific resources, videos, or even just a plain English explanation would be genuinely helpful. Exam is in 3 weeks.
