Sorry my previous message appears a mess &forum no longer allows me to edit and clear it up.
Also, I've now seen that this section of Core Reading (chapter 18 page 9) is repeated (with more elaboration) in Chapter 19 page 7-11 about risks of using past data to set assumptions.
If easiest, please (ignore my previous post and) point me to a relevant past exam question and i'll attempt it and then look at the Examiners Report. I still think there is duplication in the Core Reading list (and unclear whether similar points would each score in an exam).
