Which of the following is a topic covered in Longfellow's WHALE Tales?

The topic "Swim as a Pair Near a Lifeguard's Chair" is a key component of Longfellow's WHALE Tales program, which focuses on water safety education. This program emphasizes the importance of swimming with a buddy and near lifeguards to enhance safety in aquatic environments. Swimming as a pair can significantly reduce the risk of drowning, as one person can assist the other if needed or attract attention in case of an emergency. This teaching aligns with the fundamental safety principles that prioritize awareness and assistance in the water, making it a critical lesson for young swimmers.

The other options, while related to aspects of water safety or swimming, do not align with the primary topics covered in the WHALE Tales program. Boat maintenance and safety, underwater photography, and competitive swimming techniques may be valuable in their own right but are not the main focus of WHALE Tales, which is dedicated to fostering safe swimming practices among children.
