The correct answer is D. Select a plant from the Western Garden Book. Next, dig a hole in the backyard using a shovel.
Explanation
In most texts, the author usually refers to a sentence or detail previously mentioned. This technique allows the author to connect ideas and helps the reader to better follow the text. This technique is used in sentences A, B, and C. However, it is no used in sentence D because the author explains the reader should select a plan and after this, the reader should dig a hole. This means, the idea of the plan is mentioned only once and it is not repeated. So, the correct answer is D. Select a plant from the Western Garden Book. Next, dig a hole in the backyard using a shovel.
