In practice, the rate of increase of the orbital radius due to tidal action will not
have been constant. Suggest why this rate of change might have been different
in the very distant past.

technical wording where appropriate)
Answers based on expanding universe/galaxies/stars do not gain credit
Idea that in the past the moon was closer OR the gravitational pull
would have been larger
In the past the tidal effects would have been greater/stronger
The rate of change of orbital radius would have been greater
