Numerical answer
The five sentences (labelled 1, 2, 3, 4, 5) given below, when properly sequenced, form a coherent paragraph. Decide on the proper order and key in the sequence of five numbers as your answer.
1. More striking still, patterns of neural firing observed while rats learned a maze were found to replay during their subsequent sleep.
2. Sleep, in other words, is not time lost from learning but part of the process of learning itself.
3. For a long time sleep was regarded as a passive state, a mere absence of wakefulness.
4. Such replay, it is now thought, helps transfer fragile new memories into more durable long-term storage.
5. This view began to unravel when researchers recording brain activity found that the sleeping brain is, in some phases, as active as the waking one.

Show answer and solution
Answer: 35142
3 sets up the old view (sleep as passive) and is the natural opening.
5: 'This view began to unravel' refers directly to the view in 3 and gives the first counter-evidence (the sleeping brain is active).
1: 'More striking still' adds a stronger piece of evidence to the one in 5, namely neural replay in rats.
4: 'Such replay' refers to the replay in 1 and explains what it does.
2: 'in other words' sums up the whole argument and must come last.
Order: 3-5-1-4-2.
Tip: Build mandatory pairs first (3→5 via 'this view', 1→4 via 'such replay'). Then use the escalation ('more striking still') and the summary marker ('in other words') to place them.
