I am testing to obtain my surety license in washington state and I am having trouble locating a definite answer to a couple of questions that may or may not appear on the test. I'll start with the first one that comes to mind

'when two individuals guarantee a surety obligation, it is understood to be underwritten by a
a. special surety
b. partnership surety
c. dual surety
d. Personal surety'

I've been searching through the study material for the correct answer and cannot seem to find the correct response...it probably doesn't help that I am not able to aquire a standardized set of study materials and I am working with 8 or 9 different sources of information.

If anyone could explain the correct answer to me and point me in a solid direction for ANY substantial study material, I'd greatly appreciate it.
