Answer and explanation:
The question is asking what kind of formatting they used in this small sample of text, which are:
First, we see that the title, "Expert Systems" has a heading font applied to it to make it larger, so we can see what the text is about.
Secondly, the phrase "human intelligence" has a line through it, which means it has been struck through.
Next, we can see there is a list of four items that explain the characteristics of expert systems.
Lastly, all of the words in the list are italicized.
Hope this helps you!
