Answer 1

To differentiate among four kinds of common insects (Apex)

Answer 2

The correct answer is option C-"differentiate among four kinds of common insects".

Step-by-step explanation:

In this example a student made a dichotomous key regarding some insects characteristics. Particularly, covered wings, round body, and the presence of wings lying flat on the body. Given that the results of answering the dichotomous key are: "ladybug", "grasshopper", "housefly" and "butterfly", we can conclude that the student is trying to differentiate among four kinds of common insects. So far she or he is doing a good job since ladybugs and grasshoppers have covered wings but the first have round body and the second don't. Also, houseflies and butterflies does not have covered wings, but they can be differentiate by the presence of wings lying flat on the body.
