Question

Which word set completes the analogy? disagreement : argument ::

unskilled : inexperience
clean : spotless
worn : new
explosion : spark

Answer 1

i believe clean:spotless since were trying to compare the too in a similar matter

Answer 2

i think the word set that completes the analogy disagreement: argument is:

unskilled : inexperience

Unskilled means not having or requiring special skill or training,the disagreement with the ability or the capacity to do something, therefore the argument to complete the analogy is the inexperience,understood as the reason of the lack of skill.
