Did you find the analysis for last year's test hard to follow?

Would the test supervisor ever give rayon as a fiber to identify? It's not truly a synthetic or vegetable fiber, it's an artificial fiber, so how would you identify it?

If they did, I think you are safe calling it a synthetic:
ray·on
 –noun
1. A regenerated, semisynthetic textile filament made from cellulose, cotton linters, or wood chips by treating these with caustic soda and carbon disulfide and passing the resultant solution, viscose, through spinnerets.

2. fabric made of this filament.

Well, I haven't had any soil stuff this year, but there's some on a lot of practice tests, and to me, it's pretty easy, since you only need to look at the tracks that made the mark and look for patterns in both the tracks and the soil.

On the Nationals test it asked for the name of a fiber that's named for it's appearance. The end of the fiber kind of looked like cheese wedges. Does anyone know what fiber it is?
