Verified step by step guidance

Understand the structure of sleep cycles: Sleep is divided into several stages, including non-REM (NREM) stages 1-4 and REM sleep. Each cycle typically lasts about 90-120 minutes.

Analyze statement I: Stages 3 and 4, known as deep sleep, usually occur more in the first half of the night and tend to get shorter as the night progresses.

Analyze statement II: Each sleep cycle indeed lasts between 90-120 minutes, which is a well-established fact about sleep patterns.

Analyze statement III: REM sleep cycles tend to get longer as the night progresses, with the longest REM periods occurring in the early morning hours.

Evaluate the statements: Based on the analysis, statements II and III are true, while statement I is false. Therefore, the correct answer is II & III.
