How did eliza p. donner houghton organize her autobiography?

she started when she was older and told the story going backwards.

in sequential order from the earliest events to the later events.

she started with the present time and used many flashbacks in time.

none of the above

The answer to this question would be the first option: She started when she was older and told the story going backwards.  So in Eliza P. Donner Houghton's autobiography, it appeared like a story being told starting from the first events that she and her family have encountered up to the very last. It was actually a written account about their tragic experiences being an emigrant in the year 1846 wherein they have experienced extreme starvation and suffering.
