Final answer:
The assertion that only humans use and combine different tools is false; various animal species, including crows, otters, and chimpanzees, also use tools, illustrating that tool use is not unique to humans.
Step-by-step explanation:
The statement 'Humans are the only animals that combine the use of different tools for a given task' is False. While the human species is indeed exceptionally proficient in the invention, manufacture, and use of tools for various tasks, other animals have also been observed using tools. Instances such as a crow bending a piece of wire to form a hook to retrieve food from a tube, otters using stones to break open mollusks, and chimpanzees fashioning sticks to extract insects or achieve other tasks, clearly showcase tool use and sometimes combination of tools in other species. This suggests that the capability to make and use tools is not exclusive to humans and that several animals can display this trait, albeit less complex than human methods.
