Basic Principles | Exercise 1 question 2

Asked is to answer the sub-questions of question 1, but now for holes. With regards to the second question. The holes energy is opposite of the electron. Shouldn’t these answer be that the energy of the hole reduces as k get’s larger.

If not please help me see where I went wrong.
