Show answer & explanation
Correct answer: A
Concept
An argument is a set of propositions in which some propositions are offered as premises and one proposition is presented as the conclusion.
The defining relation is that the conclusion is claimed to follow from the premises; validity is a further property assessed after the set has been identified as an argument.
Application
Here, one proposition is claimed to follow from the remaining propositions. The remaining propositions therefore function as premises, and the proposition claimed to follow functions as the conclusion.
Contrast
An argument names the premise-and-conclusion structure itself.
A valid argument is an argument that passes the validity test: true premises cannot lead to a false conclusion.
An explanation gives reasons that clarify why an accepted fact or event occurs.
An invalid argument is an argument for which true premises can coexist with a false conclusion.
Therefore, the described group of propositions is an argument.
