Senior 4-H Rabbit Practice Exam

In this question, we are looking for the minimum number of rabbits needed to provide full-time employment. This means that we want the lowest possible number that will still be enough to sustain a full-time job. This eliminates options A, B, and C, as they are all larger numbers than D. Option A, 100 head, is too small to provide full-time employment. Options B and C, 200 and 400 head respectively, may be enough to provide full-time employment, but they are not the minimum number required. Option D, 600 head, is the correct answer as it is the minimum number that can provide full-time employment. It is important to note that while a higher number of rabbits may also be able to provide full-time employment, we are specifically looking for the minimum.
