Final answer:
The structure of an article about carving a pumpkin is likely chronological order, as this structure is best suited for outlining the step-by-step process required in carving a pumpkin.
Step-by-step explanation:
The structure of an article about carving a pumpkin is most likely to be in chronological order. This organizational pattern is appropriate because carving a pumpkin involves a sequence of steps that need to be followed in a specific order. Starting with selecting a pumpkin, moving on to designing, making cuts, removing the insides, and finally illuminating the carved pumpkin, each step must be completed before the next one can begin. This process-oriented task closely matches with a chronological structure, where events or stages are listed or arranged according to the time sequence.
While other structural options like comparison, cause/effect, or problem/solution are possible for various types of articles, for a how-to article specifically about carving a pumpkin, chronological order is the most fitting and effective way to convey the information. Ensuring the steps are presented in the order they should be performed helps avoid confusion and ensures that someone following the article can successfully accomplish their goal of carving a pumpkin.
