Question

In a memoir, authors often blend factual information about events with personal reflection on the experience. Which sentences in this excerpt from Ernest Shackleton's South! show the author reflecting on memories of his experience, rather than recounting factual information?

Answer 1

Some sentences form Shackleton's South that blend personal and objective experience are:
 
The apathy which seemed to take possession of some of the men at the frustration of their hopes was soon dispelled
(he describes here his own impressions of the apathy)

and this one: it takes a very personal stance, giving the speaker's own impressions of the diet:

Answer 2
