Analogies... Explain why you chose your answer....I tried and boy i feel smart, but my brain hurts... you...

The whole point of analogies like this is to choose pairs
where the first and the second word have the same relationship in both pairs.  So the
relationship between A and B have to be the same as the relationship between C and D,
right?  So look at this example.

What is the relationship
between a gardener and a hoe?  Well, the gardener uses the hoe as a tool in the course
of doing his or her job.

So now you need another example
where the first word uses the second word as a tool in the course of doing its job. 
Among the choices you've given, D is the best answer -- a seamstress uses a scissors as
a tool in the process of doing her job.

Painters don't
usually actually use plaster to make their paintings.  A judge's ruling is pretty much
what they are trying to make, now what they use to make it.
