People who attempt to jump of buildings are likely to do themselves more harm than good unless they have they something soft to land on...
Kind of a dark answer choice but the question stands! Thanks.
Take it in steps (our last step here will give us the only two
steps you'll have to take in future. But first, I'll walk you all the way through the thinking):
1. Symbolize the conditional relationship (For a primer on a simple, mechanical way to symbolize "unless" statements, you can watch this free video lesson
2. You'll end up with this:
no Soft Landing --> Harm
no Harm --> Soft Landing
In other words, the meaning of your sentence is that a soft landing place is necessary to avoid doing "more harm than good" (which I've abbreviated here as "harm").
3. To negate any answer choice, you can
always append the words "it's not true that..." to the front. Doing that, what we get in this instance is "It's not true that
avoiding harm requires a soft landing".
4. We can reformulate that symbolically:
~ (no H --> SL)
5. So, your mechanical means of negating an unless
-type statement boils down to two steps:
1. Formulate the choice symbolically.
2. Negate that symbol set.
Let's finish with another example:
You can't eat carrots unless you have teeth.
no T --> no C
C --> T
~ (C --> T)
And we end up with this: "It's not true that eating carrots requires teeth."
Hope that helps.
