Final answer:
Using the given conditions about parcel delivery sequences, we concluded that J is the parcel delivered fourth.
Step-by-step explanation:
The student has asked which parcel is delivered fourth, given a series of conditions about the delivery order of eight parcels G, H, J, K, L, M, N, and O. To answer this, we will use the provided conditions to deduce the sequence.
The parcels must be delivered in an order that satisfies the following conditions:
- G is delivered before J and after K.
- L is delivered after J and before O.
- M is not delivered first or last.
From these conditions, we can begin to outline a possible sequence:
- ...
- K (K must be before G and thus cannot be first).
- G (As it comes after K).
- J (Because G is before J and L is after J).
- ...
So, we can conclude that J is the parcel delivered fourth.
