The answer is A. This summary is weak because it leaves out the resolution of the story
Explanation:
The resolution of a story refers to the end of the story or section of the story, in which the conflict is completely solved. This section of the story has not been included in the summary because the author of this summary does not tell the reader if the main conflict (attack by the wolf) is solved or the final situation of the main characters (the girl, the grandmother, and the wolf). Moreover, this makes the summary to be incomplete or weak as each of the stages of a story including the resolution should be part of the summary.
