When writing an argument, sometimes including a single viewpoint as Support is enough to have it make sense. However, in some instances the writer will need to include a supporting argument that also has its own support to force the argument to make sense.
For example, in the Carole Baskin article, the writer could end viewpoint 7 with the supporting viewpoint 7.c. ("Lewis was never seen again since 1997"). However, the argument makes more sense when it includes 7.c.i. and 7.c.ii., giving two elements of support for why "The disappearance itself was extremely strange."
