Answer:
killed
Step-by-step explanation:
According to a different source, the excerpt that is included with this question is:
"Why don't they hurry, why don't they hurry ..." muttered Jem. We saw why. The old fire truck, killed by the cold, was being pushed from town by a crowd of men."
The "connotation" of a word is a commonly understood association that a word has, in addition to its literal meaning. The literal meaning of the word, on the other hand, is called "denotation." In this example, the word "killed" refers to the truck being unable to run. This is a connotation of the word "killed." It cannot be the denotation because the truck was never alive and thus cannot be literally killed.
