The correct answer is B) approximately 1/2 inch shorter than the measured length to allow for wedges. The reasoning behind this is that when shoring a bulkhead, the shore should be cut slightly shorter than the measured length to allow for the placement of wedges. The wedges help secure the shore in place and prevent it from loosening over time. Cutting the shore approximately 1/2 inch shorter than the measured length provides the necessary space for the wedges, ensuring a tight and secure fit. The other options are incorrect because: A) cutting the shore to the same length as the measured length would not allow for the wedges, C) cutting it 1/2 inch shorter per foot to account for wet expansion is unnecessary for this specific task, and D) cutting it longer than the measured length would make it difficult to properly fit and secure the shore.
