The duty of the lighthouse keeper is to keep the light burning no matter what happens, so the ships will be warned of the presence of dangerous rocks. if a shipwreck should occur near the lighthouse, even though he would like to aid in the rescue of the crew and passengers, the lighthouse keeper a. turn out the light. b. quickly sound the siren. c. stay at his light. d. rush to their aid. asvab q. thx! : )
