Read this excerpt from chapter 1 of i know why the caged bird sings by maya angelou and answer the question.

when i was three and bailey four, we had arrived in the musty little town, wearing tags on our wrists which instructed – ‘to whom it may concern’ – that we were marguerite and bailey johnson jr. … negro passengers, who always traveled with loaded lunch boxes, felt sorry for ‘the poor little motherless darlings’ and plied us with cold fried chicken and potato salad.

in the above excerpt, angelou uses her diction to portray the children as

a metaphor for luggage
an exaggeration of the facts
an allusion to the runaway train

The answer is B: an exaggeration of the facts.

Explanation:

We know that Angelou's use of diction in this passage, is an exaggeration to the facts mostly for the following line: "wearing tags on our wrists which instructed – ‘To Whom It May Concern’ – that we were Marguerite and Bailey Johnson Jr. …" It's obvious this is figurative, it's just a way to let the audience know they were "motherless" and "alone in the world", an exaggerative way to let it know. The other two options cannot be possible as the whole passage not only gives the Runaway Train background, but also "a little town". And luggage, although it doesn't have to be directly stated, is not possible, for the whole passage focuses only on the girls and passengers.

. a function is a relation in which each input has only one output. in the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
