C. Reduced sleep duration over extended periods	F. plays a decisive role in shaping coastal trade routes

Correct Option: A–E only

To identify the correct matching between Column I and Column II, let us analyze the context and grammatical structure of each sentence fragment.

Analysis of Column I Parts:

• Part A: "Irregular sleep schedules among teenagers during school weeks"
This subject focuses on health and behavioral effects on teenagers, which logically links to emotional, cognitive, or academic outcomes.

• Part B: "Staying awake late to complete unfinished assignments"
This phrase describes a common study habit or action, requiring a verb phrase that naturally addresses sleep deprivation or academic stress.

• Part C: "Reduced sleep duration over extended periods"
This phrase describes long-term sleep loss, which relates to health outcomes or systemic effects.

Analysis of Column II Parts:

• Part D: "was introduced as a ceremonial tradition in ancient kingdoms"
Refers to historical traditions or royal customs, which has no logical connection to sleep, assignments, or teenage health.

• Part E: "often affect alertness, mood stability, and academic engagement"
Refers directly to the psychological, emotional, and cognitive consequences of sleep disruptions.

• Part F: "plays a decisive role in shaping coastal trade routes"
Refers to geography, trade, and maritime commerce, which has no logical connection to any sleep-related topic.

Evaluating Potential Pairings:

1. A–E: "Irregular sleep schedules among teenagers during school weeks often affect alertness, mood stability, and academic engagement."
This forms a completely meaningful and grammatically sound sentence, connecting teenage sleep habits with their direct effects on mood and academic performance.

2. B–D: "Staying awake late to complete unfinished assignments was introduced as a ceremonial tradition in ancient kingdoms."
This pairing is logically nonsensical.

3. C–F: "Reduced sleep duration over extended periods plays a decisive role in shaping coastal trade routes."
This pairing is logically absurd.

Therefore, the only correct and meaningful pair is A–E.
