Final answer:
The statement is true; a landowner must warn a licensee about known dangers unlikely to be discovered, but has no obligation to inspect or repair such defects.
Step-by-step explanation:
A social guest is considered a licensee, which means they enter the land with the owner's permission for their own purposes or benefits. This status of the visitor imposes certain duties on the landowner. Specifically, the statement provided is true: the landowner has the duty to warn a licensee about dangerous conditions on the property that are known to the owner, pose an unreasonable risk of harm, and are unlikely to be discovered by the licensee. However, the landowner does not have a duty to inspect for defects nor to repair known defects for licensees. There's a key distinction in terms of responsibility, hinging on the assumption that the licensee assumes some risk by entering the property mainly for their own benefit.
