Explanation

The question asks which word is different regarding nouns. “Shara” means sweeping, which is an action. It describes what you do, not a thing.

The other words are all concrete nouns. “Gida” is house. “Kwano” is bowl. “Rafi” is river. These are all things you can see or touch.

Nouns name people, places, or things. Action words are verbs. Knowing the difference helps you use words correctly.
