Answer 4

The animals having backbones are called vertebrates. To arrive at this answer, you can break down the question into parts. First, you notice that the question is asking for the name of animals that have backbones. This suggests that you need a specific term to describe these animals. One way to approach finding this term is to think about the characteristic mentioned in the question, which is the presence of backbones. Then, you can consider the options provided: "strong," "invertebrates," "complex," "simple," and "vertebrates." By going through each option, you can eliminate those that do not fit the characteristic of having a backbone. For instance, "strong," "complex," and "simple" do not directly relate to having a backbone, so they can be eliminated as possible answers. This leaves you with "invertebrates" and "vertebrates." The prefix "in-" usually denotes a negation, so "invertebrates" would mean animals without a backbone, which is contrary to what the question is asking. Therefore, the correct answer must be "vertebrates."
