Which excerpt from "the evacuation" is the best example of the author's personal theme during her evacuation to cornwall?

can you imagine people doing that today--parents allowing their children to be taken to a strange place, to live with unknown people?
they expected us to be dirty, full of lice, and crude. (you know, to be honest, some of us were, but still, we were just kids! )
i kept telling myself, "pull yourself together, pull yourself together," so i wouldn't cry.
"we's together. where she goes, i go, 'cos she's my sis and you can’t separate us."

ian mortimer in his book "the time traveller's guide to elizabethan england" uses a narrative in his style, which successfully conveys a clear description of the life in england in the 16th century. he writes in second person, which makes it comfortable to reader and easy to understand, he captures the readers attention with views of the landscape, the streets, the people including rich and poor. he also depicts some cultural traits from how people behave, eat or what they wear. his descriptions range from the social, economical, the political power to the examples of the life of common people. it could be tell that this book is about social history rather than a   novel.

i believe the answer is b: the narrator.

the answer is a)simple future tense
