Answer:
The answer is: letter B, after sentence 1 because Joanne is describing her entire trip.
Explanation:
Joanne is narrating her trip upon visiting her aunt and uncle in Valencia, Spain. The way the story flows, it seems like Joanne had a great time during her visit. <em>So, this means that her entire trip experience was incredible.</em>
Sentence 7 (The experience was incredible.) should be placed after sentence 1 <em>because Joanne is trying to tell the reader that her experience was, indeed, incredible. </em>After stating it, she goes on telling the details one after the other.
Putting the sentence in-between would divide the thought of the narration. If you put the sentence after 4, 5 or 8, it would feel indifferent to all the other sentences because everything she's written is a positive experience for her. Thus, everything she experienced is incredible.
<u>Putting it after sentence</u><u> 1 is the best way to reveal her thoughts.</u>
Thus, this explains the answer.
