The best organizational style for an instructional guide describing how to build a birdhouse would be sequential. Here's why:
1. Sequential organization presents information in a step-by-step order, making it easier for readers to follow along and understand the process of building a birdhouse.
2. When creating a birdhouse, it is crucial to follow a specific sequence of steps, such as cutting the wood, assembling the pieces, and adding finishing touches. Sequential organization aligns well with this structured process.
3. By using a sequential organizational style, the guide can ensure that readers are guided through each stage of the construction process in a logical and clear manner, minimizing confusion and promoting effective learning.
