Question

when does noise become noise pollution? only when anyone can hear it only during very rainy nights when its a sound thats pleasant when it disrupts daily activities

Explanation:

To determine when noise becomes noise pollution, we analyze each option:

• "only when anyone can hear it": Noise exists when audible, but pollution requires disruption, not just audibility. Eliminate.
• "only during very rainy nights": Rainy nights don’t define noise pollution; it’s not time/weather - dependent. Eliminate.
• "when it’s a sound that’s pleasant": Pleasant sounds aren’t pollution. Eliminate.
• "when it disrupts daily activities": Noise pollution is unwanted noise that interferes with life, so this fits.

Answer:

when it disrupts daily activities
