@Richmond So what we know from the prompt is that rats with various disabilities, as well as non-disabled rats, made it through the maze in a similar time, indicating that any one of their senses tested were not strictly necessary for learning the maze. We also know that they didn't test the ability of kinesthesia, so the researcher assumes that's the ability needed, alone, for getting through the maze. (Is sufficient for...)
There seems to be a gap in the researcher's logic. It could just be kinesthesia that's needed, but perhaps they also use their other senses. No rats, from what we were told, lacked ALL other senses than kinesthesia, so it's perfectly possible that they still relied on their remaining senses to get through the maze, in addition to kinesthesia.
