1. A. 4

2. B. 6

3. C. 5

4. D. 3

The correct answer is: A. 4

The minimum required number of anchor bolts for an eighteen-foot long sill plate in a single-family dwelling is a crucial aspect of ensuring structural integrity and safety. According to the Massachusetts State Building Code, specifically regarding residential construction, the general requirement is that anchor bolts must be spaced no more than six feet apart along the sill plate. Given that the sill plate in this scenario is eighteen feet long, it would require multiple anchor bolts to adhere to this spacing guideline. By this standard, a minimum of four anchor bolts is necessary: two bolts for the first twelve feet (spaced at six-foot intervals) and at least one additional bolt for the last six-foot section to maintain compliance with the spacing requirement. Therefore, the correct answer reflects this minimum requirement, ensuring sufficient anchorage to the foundation, which helps prevent potential movement or uplift during adverse weather conditions.
