1. 4

2. 6

3. 5

4. 3

The correct answer is: 4

The minimum required number of anchor bolts for an eighteen-foot long sill plate in a single-family dwelling is four. This is in accordance with the building codes, which provide guidelines for securing the sill plate to the foundation to ensure structural integrity and resistance to lateral forces such as wind and seismic activity. The requirement typically states that anchor bolts should be placed no more than six feet apart, with additional bolts required at each end of the sill plate. Thus, for an eighteen-foot length, having four anchor bolts ensures the sill plate is sufficiently secured and meets safety standards.
