I have four keys on a ring. Each key unlocks a different door: Bronze, Copper, Silver, and Gold. - The Gold key is neither first nor last in the sequence. - The Bronze key is immediately next to the Silver key. - The Copper key is the very first key. In what position is the Bronze key if you check them from first to last?
Third
The Copper key is first (Position 1). The Gold key cannot be first or last, and since first is taken by Copper, Gold must be in either position 2 or 3. The Bronze and Silver keys must sit side-by-side. The only available adjacent spots are positions 2-3 or 3-4. If Gold is in position 2, then Bronze and Silver must take positions 3 and 4, leaving Gold out of the middle? Wait. Let's map: Copper = 1. Gold = 2 or 3. If Gold = 2, Bronze and Silver must be 3 and 4. If Gold = 3, Bronze and Silver must be 1 and 2 (but 1 is Copper, so no). Therefore, Gold must be 2, and Bronze/Silver take 3 and 4. Since Bronze is next to Silver, Bronze is either 3 or 4. Wait, if Gold is 3, can Bronze/Silver be 1/2? No, Copper is 1. Can Bronze/Silver be 4/5? There are only 4 keys. Let's re-verify: Copper=1. Gold cannot be 1 or 4, so Gold is 2 or 3. If Gold=3, spots 1,2 are left for Bronze/Silver, but 1 is Copper. So Gold cannot be 3. Thus Gold must be 2! That leaves positions 3 and 4 for Bronze and Silver. Thus Bronze is either 3 or 4.
