This is the given question for a grade 6 student during his exams. I was asked to provide an answer for him but I have a few doubts.
The Attempt at a Solution
I know that option B is definitely wrong as the 4 spiders could easily be of the same species. Similarly option D is wrong as 19 populations of animals would imply 19 different species of animals and that cannot be concluded from the diagram. That leaves only options (1) and (3) as the only possible correct answers. I understand why E is correct. However, I would have thought A and C would also be correct.
