Which of the following is an OXYMORON ?

The dull bright afternoon looked no different

The answer is The dull bright afternoon looked no different.

An oxymoron is a figure of speech in which two contradictory terms are used together. In this case, the words "dull" and "bright" are contradictory terms. Dull is typically thought of as being dark and lacking in light, while bright is typically thought of as being light and shining. The use of these two contradictory terms creates a sense of the afternoon as being both bright and dull at the same time.

The other answer choices are not oxymorons. The night sky with all the stars can be a map for the traveler, as the stars can be used to navigate. Anita singing like a professional singer is not an oxymoron, as it is possible for someone to sing like a professional singer. Amazing aunty Agatha opened the door is not an oxymoron, as it is possible for someone to be both amazing and aunty Agatha.

The oxymoron "dull bright afternoon" is a powerful image that captures the paradoxical nature of the afternoon. It is often used to describe the feeling of boredom or monotony that we can sometimes experience during the afternoon.
