To determine which response best fits the plot contribution of Paragraph 1, we need to assess the information given.
If Paragraph 1 describes a situation where Justin and his father are engaged in a fishing activity when a storm suddenly occurs, then the appropriate response would be:
A. Justin and his father are fishing when the storm hits.
This directly contributes to the plot by establishing the setting and conflict (the storm) that the characters face during their fishing trip.
If you have more context about the paragraph or additional content, please share, and I can provide a more tailored response!
