Answer: slung
Explanation:
The word that means "thrown carelessly " in under a telephone wire poetry is " slung".
The first line in under a telephone wire poetry reads that "I am a copper wire sling in the air". Slung simply means when something is going or thrown casually. In such scenario, the copper wire is carelessly thrown in the air.
I believe it is a claim because it does focus on the main idea and what the text/passage should be about. If not I deeply apologize.
