Is there a mistake on this GCSE Astronomy mark scheme?

In yesterday’s tuition sessions I encountered an issue, where I could not justify what the mark scheme said about a question. After some more thought, I believe there are mistakes on the mark scheme for this question. Watch the video below to see my thoughts.

Am I wrong? Please do let me know if I’m doing something dopey!
