CorrectNot quiteAnswer D

Correct answer: D

Candles exist, every candle is a lantern, and no candle is a torch. So those lanterns are not torches: I follows.
The lamps that are torches cannot be candles. So some lamps are not candles: II follows.
Both I and II follow.

Worth noting

The 'No' in the middle pays off twice: through the candles (an All link) it gives 'Some lanterns are not torches', and through the lamps (a Some link) it gives 'Some lamps are not candles'.

Concept: No in the middle of a chain gives Some … not twice
