I read everything above, but I am still kind of struggling with negating answer choices that are conditional. I know that the goal is to show that the sufficient condition can occur without the necessary condition, but I don't always know how to construct that in my head.
For instance, I saw this answer choice on a problem: If the town officials did not follow their own advice then that advice is not worth following.
I negated this to say: The advice is worth following even if the town officials did not follow their own advice.
Is this correct?
Do you have any tips for increasing speed with negating conditional statements?
In time, you will find negating conditional statements is actually fairly easy, but you have to follow a simple formula for it. Once you see how that works and try it a few times, it will get much much faster for you
Here's the basic formula: whatever they say is necessary, isn't. That doesn't mean it can't ever occur, it just means that it's not required
. Let's look at a few examples:
- "To lower CO2 emissions, we must use wind power." — Here, the conditional statement indicates that "using wind power" is necessary. So, to negate the statement, simply state that wind power isn't necessary. Because English is so variable, there are many different ways to state that, but here are two that work: "To lower CO2 emissions, wind power is not necessary" and "We can lower CO2 emissions without having to use wind power."
The above example shows how the negation is very direct—it just knocks out the necessity aspect of the necessary condition. Of course, that's stated in a very simple form, but the principle applies even if the conditional statement is a bit more challenging:
- "People who do not recycle do not deserve tax breaks." — Here, the statement contains a set of negatives, which bothers many people. But the process is still the same. First, the statement can be diagrammed as: Recycle Tax Breaks. Now, to negate, we make the necessary condition not necessary any more: People who do not recycle still might deserve tax breaks" (or any of multiple variations).
If you look at that second example, it's very similar to the example you asked about, which would just be a variation on " If the town officials did not follow their own advice then that advice might be worth following." That's basically what you said, so you were right
The real key here is that once you see this process clearly and try it a few times, it gets much faster and easier.
Please let me know if that helps. Thanks!
