It would be best to start by saying which railway's practice you're using, suggest you write that at the start of every question's answer in the exams.
You've put a reasonable amount of material in your lists but very little for reasons/discussion. Note what PJW said of my attempt:
Note the subtle wording of the question:
Route = "expect", "reasons"
Beyond = "could be included", "reasons for inclusion or exclusion"
Adjacent = "may need to be proved", "reasons for consideration".
When you plan your answer, keep in mind that at least half the marks are going to be for the reasons. We sometimes fail to state the obvious, such as in the first part that [tracks clear and points set, locked detected] are in order to provide a safe wheeled path.
First section - instead of your note on the aspect sequence, it might have been better to comment on having a defined end of MA i.e. next signal lamp proved. I disagree slightly with your friend's comments on foul tracks - would be better in the third part.
Second section - I think a discussion on why different classes of route have overlaps, and why we use the lengths we do is expected, plus points in the overlap - whether they are locked or allowed to swing, and why they are/are not detected.
Third section - I think your friend is right that CAR is not relevant, but put in flank protection and foul tracks here. Overrun controls also fit, I came up with trip wires as another example.
