Manhattan LSAT LR p392

[YvonneS601]

Hello.
In the middle of page 392,
It is written as... “Now, we’re looking... one or both of these conditional statements”

I don’t understand why it could be ‘one or both’
It should be ‘BOTH’ because the two necessary conditions are connected with ‘AND’; first, doing so harms the one to whom the promise is made AND second, all of those who discover the failure to keep the promise lose confidence.

Did I miss something wrong?

Happy to clarify! In Principle Example questions, like with many LR questions, the question stem asks what most fits, not what fits 100%. So you could have an answer that conforms to only one of the conditional statements, as long as the other answer choices violate the conditional statements in some way and can therefore be eliminated.

Reminder to always work wrong to right!
