CorrectNot quiteAnswer A

Correct answer: A

Every spanner is a wrench and every wrench is a lever, so all spanners are levers. Spanners exist, so some levers are spanners: I follows.
The hammers that are not spanners may still be levers (the lever circle is bigger). All hammers could be levers, so II is not definite.
Only I follows.

Worth noting

'Some … not' does not carry forward through an All. Being outside the small circle says nothing about the big circle around it.

Concept: Some … not does not pass through All
