In argument diagrams, arrows are drawn:

A) between two premises
B) between two conclusions
C) beneath all individual propositions
D) from a conclusion to its premises
E) from premises to their conclusion

In argument diagrams, arrows are drawn from premises to their conclusion, indicating the logical flow of the argument. Therefore, the best choice is E. Arrows do not typically connect two premises or two conclusions, and they are not drawn beneath individual propositions. Arrows may also be used to indicate sub-arguments or support for a premise, but their primary purpose is to connect the premises to the conclusion.
