Explorers on an Island

Four explorers set sail on a daring expedition to a legendary uncharted island. Each explorer possesses a unique skill:
Anya: Can build a fire with any materials.
Ben: Can speak the language of any animal.
Clara: Can navigate by the stars, even on cloudy nights.
David: Can climb any tree, no matter how tall.
To survive on the island, they need to complete three crucial tasks:
Signal for help: Build a fire large enough to be seen from afar.
Gather food: Understand and communicate with the island's animals to locate food sources.
Find shelter: Navigate through dense jungle to reach a hidden cave rumored to offer protection.
However, there's a twist: only two explorers can work on each task, and each explorer can only participate in one task.
Question: Can the explorers complete all three tasks using their unique skills? If so, who should work on each task?

Solution: Signal for help: Anya and David. Anya can build a fire with any materials, and David can climb any tree to gather dry wood and leaves. They can also use the height of the tree to make the fire more visible.
Gather food: Ben and Clara. Ben can speak the language of any animal, and Clara can navigate by the stars. They can use their skills to find and communicate with friendly animals that can lead them to food sources. They can also use the stars to avoid getting lost in the jungle.
Find shelter: Clara and Anya. Clara can navigate by the stars, and Anya can build a fire with any materials. They can use their skills to find the hidden cave that offers protection. They can also use the fire to scare away any predators or insects.
This way, each explorer participates in one task, and each task is completed by two explorers.
