I suppose the underlined word is respite. Its closest word in meaning is break. As a noun, respite means a short period of relief or rest. From the context, we can see here that the instructors had quite a hard job of taming the canines, so they needed to use any chance they had to get some short rest before going on.

The correct answer is "The grandmother represents old southern culture in the story because she is racist, selfish and evil but appears to be a good southern lady on the outside". "A Good Man Is Hard to Find," first published in 1953, is one of the most Flannery O'Connor's famous stories. O'Connor was a staunch Catholic, and like most of her stories, "A Good Man Is Hard to Find" are about good and evil and the possibility of divine grace. The grandmother gives great importance to being "a lady," and her ideas about what that means reflect an old-fashioned, somewhat upper-crust Southern mindset. All end up in her to associate being "good" with coming from a respectable family and behaving like a member of her social class.
