Subordinate clause.

Explanation:

The given sentence employs a subordinate clause "that they could outsmart the law" which illustrates the dependent clause. The subordinate clause usually begins with a subordinate conjunction or a relative pronoun. It displays a fragment that depends on the principle clause to determine its meaning. Thus, the sentence employs a subordinate clause that exemplifies a dependent clause and describes the additional information to complete the thought or statement.

in the line from the end of the story "the cask of the amontillado," by edgar allan poe, the narrator has put the last stone on the wall, thus sentencing fortunato to death. just like that montresor associates his feeling of sickness to the humidity of the catacombs, and seems to be glad he has taken revenge on fortunato. however, montresor's last words are "in pace requiescat," which mean "may he rest in peace." as a result, it can be inferred that he hides or does not want to assume his guilt or remorse for killing fortunato in such a horrible way.
