Statement: A study found that people who sleep less than 5 hours are at higher risk of heart disease.
Inferences:
1. Lack of sleep is a contributing factor to poor health.
2. All people must sleep exactly 5 hours to avoid disease.
Show answer & explanation
Correct answer: A
Explanation
Analysis of Inferences:
• Inference 1: The statement indicates that sleeping less than 5 hours increases the risk of heart disease. This directly implies that inadequate sleep negatively impacts health. Thus, Inference 1 follows.
• Inference 2: The statement mentions a risk for sleeping less than 5 hours; it does not state that people must sleep exactly 5 hours. Therefore, Inference 2 does not follow.
Hence, Only Inference I follows.
