Answer: It's indeed as follows
impetuous: rapid and powerful
barbarously: coarse and uncivilized
impious: disrespectful, irreverent
preposterous: absurd, unreasonable
Explanation:
Let's take a look at the definitions for each word:
impetuous --> this adjective refers to something or someone that movies rapidly, forcefully, relentlessly. Another possible definition refers to someone who does something carelessly, but that is not the contextual definition needed for the question we're working with here.
barbarous --> this adjective originates the adverb "barbarously" we can see in the question. Barbarous is something or someone that is uncivilized, primitive, as well as something or someone that is cruel, monstrous, merciless.
impious --> this adjective usually refers to someone who is disrespectful, irreverent towards a god. In a lighter tone, it can refer to someone who acts in a wicked way.
preposterous --> this adjective defines something that is illogical, senseless, absurd, or ridiculous.
