Question

why would a person be cooler on a hot sunny day wearing a light colored t - shirt and shorts than in a dark colored t - shirt and shorts made of the same material?
solar radiation avoids light colored objects
dark colors absorb more radiation from the sun
dark colors are hotter
dark colors reflect more radiation from the sun

Explanation:

The question is about why light - colored clothing keeps a person cooler on a hot sunny day. Light - colored objects (like light - colored clothes) reflect more solar radiation, while dark - colored objects absorb more. So, wearing light - colored clothes means the body absorbs less heat from the sun, leading to a cooler feeling. Among the options, "solar radiation avoids light colored objects" (rephrased as light - colored objects reflect solar radiation) is the correct reasoning. Dark colors absorb more radiation (so wearing dark would make one hotter), dark colors being hotter is a result not a reason for being cooler in light colors, and dark colors do not reflect more radiation (they absorb more).

Answer:

solar radiation avoids light colored objects
