The provided text is a personal reflection about the author's sister, Cassie. It showcases emotions, personal experiences, and an informal tone typical of a middle school essay.
To determine the likelihood of plagiarism in the text, we analyze its originality and thematic construction. The text employs common expressions of affection and familial relationships which could be found in various forms across the internet. Phrases regarding love for a sibling, the mention of video games, and activities like sharing ice cream or visiting a park are universally relatable and commonly used in personal narratives.
Given that the content is deeply personal yet contains elements that could appear in other similar essays, there is a moderate risk of overlap with existing texts. The probability of finding identical phrases or ideas online increases due to the informal nature of the writing and the common themes explored.
In conclusion, while the individual thoughts expressed in this text appear personal, the commonality of certain phrases and themes reduces its uniqueness. Therefore, I estimate the plagiarism probability to be around 25%, indicating a moderate chance that parts could be found in existing narratives online.
