How can I word this sentence, so it isn't a fragment?

Question

For example, the discovery that a medicine can be used for more than one ailment.

Answer 1

A medicine, that can be used for more than one ailment,
was discovered.

Answer 2

This is somewhat difficult without knowing what the previous sentence was, but are you perhaps explaining what a discovery is? Or are you listing examples of the discoveries that a particular person made?
If either one of those is the case, then I'd word it "For example, it was discovered that a medicine can be used for more than one ailment."
If you have more information, like the date of this discovery or an example of one medicine/two or more ailments, that would help to make this sentence more complete.

Answer 3

You could possible word it. I have come across information that there has been a discovery that a medicine can be used for more than one ailment.

Answer 5

The discovery that a medicine can be used for more than one ailment is one example of this.

Every sentence has to have a subject, and a predicate. Your sentenced has a subject: example. But it does not have a predicate. To change this, ask yourself what you are writing about. You will find that it is the discovery. Change the sentence to make this the most important part of your sentence. "For example" is merely an introductory phrase.
