"some" Diagram Question

keeper962

PT70 Section4 # 17
For #17: Parallel Form
I got confused on how to diagram it (I understood everything except how to diagram (Note: the way I diagram for these is using broad A-->B,etc since the context isn't important but the form of the logic is):
The stimulus says that:
-some halogen lamps are well-crafted
-because halogen lamps from most major manufacturers are on display at FL
-and any item on display at FL is well-crafted

I wrote it as
some A-->B or A<--some->B
A-->C
C-->B

But my diagram is wrong for:
because halogen lamps from most major manufacturers are on display at FL

it should be A<-some->C

why is it some?

some A-->B

Have you gone through the curriculum? I would just diagram this A some B

Premise: halogen lamps from most major manufacturers are on display at FL ( HL some OD)
Premise: any item on display at FL is well-crafted (OD-->WC)
Conclusion: some halogen lamps are well-crafted (HL some WC)

Abstract:

A some B --> C
_____________
A some C

Hope this helps.
