Which one of the following passages best suggests an indirect cause?
You have to know the fairy tale of “Jack the Giant Killer,” and that “he” in the third sentence refers back to Jack. Thus, an indirect cause is suggested by:
Jack slew the giant because he (= Jack) sold the cow for magic beans.
In the story, Jack sells a cow for magic beans.
He plants the magic beans, which grow into a tall vine he can climb into the sky.
Because he climbs the vine, he ends up in the kingdom of the giant, who Jack eventually kills.
Thus, trading the cow for magic beans indirectly led to Jack killing the giant.
