Passage Summary: We like music with simple beats because it reminds us of the safety and the heartbeat we heard while in the womb.

Conclusion: It is natural for people to be drawn to simple rhythmic sounds throughout their lives as a way to seek warmth and security.

Reasoning: The first sound a fetus hears is the mother's heartbeat, and because birth removes that constant comfort, humans instinctively seek to replicate that feeling through similar rhythms.

Analysis: This is a classic 'Identify the Conclusion' task where the final sentence, introduced by the indicator 'Thus,' serves as the main point. The earlier sentences provide a biological and psychological explanation for why this attraction exists, but they are all leading up to the claim about human behavior in later life. When analyzing the structure, notice how the argument moves from a specific observation about the womb to a general rule about human nature. It’s a cozy theory, but your job is simply to pin down the final destination of the logic.
