Which sentence is an example of a metaphor? the bear was big and brown. the squirrel scurried up the tree. the cat's purr was a soft lullabye. the lion's roar was fierce and scary.

The cat's purr was a soft lullaby

Explanation:

The other answers are just descriptions of the animals aka adjectives, which are facts e.g the bear is big and brown is a factual way on describing a bear while the cat's purr was a soft lullaby is a figure of speech which is not literally applicable. Others could describe it differently, by using metaphors such as cat's purr was a lovely melody but factually and adjectival we could say about the cat that it's purr was nice.

For me it is not important to win at any cost there are many more important things always listen to your heart and rely on yourself. Be yourself and know that if you lose it will not prevent you from winning next time and do not give up. There is always something that helps you.
