The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The meaning of the quote "Without feelings of respect, what is there to distinguish men from beasts?" is the following.
It means that humans have characteristics that clearly separate them from animals. Among those characteristics that make us humans and not animals, are the use of our brain to think, and therefore, to show respect, to show compassion, and be tolerant to help other humans.
Without those characteristics, humans would behave like animals, like beasts, or savages. And that is not the case.
That quote is attributed to the great Chinese thinker and leader, Confucius.
