Hey
Which is a reason the Nile has been called "the lifeblood" of Egypt?

Basically farming

Explanation:

During the annual flooding of the Nile, which typically lasted from July through November, farming was impossible. But when the waters receded, a thick layer of fertile silt over the farmlands remained to insure rich soil for their crops and thick grasses for their grazing animals

the narrator is a first person, participant one, who describes in the simple past tense important and difficult events in his earlier life. he also provides temporal markers as the month (january) and the time (12: 30 pm). finally the account of his experience is very detailed, to the extent that a participant narrator would talk the same way about his experiences. a good example of such detail is the mention of the “bovril ration” which historically was a native american food adopted by european explorers in arctic and antarctic regions due to its high level of calories.
