Final Answer:
The reasons why this is a bad paraphrase are C (Unnecessary details are included) and D (Paraphrased text is longer than the original).
Step-by-step explanation:
The paraphrased version includes unnecessary details that were not present in the original text. For example, the statement "Grandpa lives on a farm and which is a great place to spend your weekend" adds redundant information, as the original already conveys that farms are a great place to spend the weekend. This contributes to the paraphrased text being longer than the original, aligning with reason C and D.
Additionally, the paraphrased version fails to change the direct quote "My horse is my best friend!" into reported speech. In the original text, Grandpa says this about his horse, but in the paraphrased version, the quote is retained verbatim. This lack of transformation from direct to reported speech is a deviation from proper paraphrasing, supporting reason B.
In summary, the paraphrase contains unnecessary details, retains the original quote without converting it to reported speech, and is longer than the original text. These factors collectively contribute to the inadequacy of the paraphrased version.
