The sentence is not listed, but the word impending means something that is about to occur (synonyms include upcoming, coming, near, to come, on the way etc.)
Hello!
The answer would be "focusing on minor details." This would not be a feature of a good summary because the purpose of a summary is to restate the main points or events in a piece of writing without focusing on details that are not important to the main idea.
Hope this helps!
