PT70 Section4 # 17 Diagram Question

keeper962

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 impotrant 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?

Bumping this to the top so users can see it!

The conclusion is a some statement because a most statement can always be reworded into a some statement. Some can mean anything from 1 to all (which therefore includes the possibility of more than 50%). It's sort of like saying a square is also a rectangle, it's just a special type of rectangle. A most statement is also a some statement, it's just a special type of some statement (one that means greater than 50%).
