Final answer:
The 'higher intelligence' beings from planet 42711 were distinct from Captain Neila's team as d. they couldn't undertake distant space travel.
Step-by-step explanation:
The creatures of "higher intelligence" from planet 42711 differed from Captain Neila and his crew in that they were not capable of distant space travel. This suggests that while they may have had a form of intelligence, it did not extend to the technological advancements necessary for space exploration as had been achieved by Captain Neila's civilization. This distinction between cultures underlines different paths of evolutionary and technological development, where one species may be advanced in one area, such as possibly communication or society, while another excels in technology as evidenced by interstellar travel capabilities.
The creatures of 'higher intelligence' from planet 42711 were different from Captain Neila and his crew in several ways. They did not have an alphabet or a written language (a), meaning they did not communicate through written symbols. Instead, they communicated only by touch (b), using physical contact to convey messages. Additionally, they traveled only by walking, rowing, or riding animals (c), which suggests that they did not have advanced technology for transportation. Lastly, they were not capable of distant space travel (d), meaning they did not possess the means to explore other planets like Captain Neila and his crew did.
