III. hasty generalization
A syllogistic fallacy is more of a generalization than it is a sequence or analogy. This error of reasoning occurs by first mentioning something broad/general then proceeds to make a conclusion about something that is very specific by means of generalizing. For example, this would be considered fallacy of syllogism:
All jets are air crafts. All propeller airplanes are air crafts. Therefore, propeller airplanes are jets.
Thus, you can see how a generalization is made about propeller airplanes being jets because they are both air crafts.
A counter argument you might see is how performance enhancing drugs can benefit in a competition
The word that goes, or better expressed, is a synonym for edge is: precipice because it has both the literal and metaphorical connotations just as edge does. It means a very steep or overhanging place, like in a cliff, and it also means to be at the brink of a situation just like edge.
The other words do not match both or any of the definitions of edge.
The answer is D because this is Expository, meaning to entertain.
