Bent to the earth ,to where does the narrator his mother and father go

They had hit Ruben

with the high beams, had blinded

him so that the van

he was driving, full of Mexicans

going to pick tomatoes,

would have to stop. Ruben spun

the van into an irrigation ditch,

spun the five-year-old me awake

to immigration officers,

their batons already out,

already looking for the soft spots on the body,

to my mother being handcuffed

and dragged to a van, to my father

trying to show them our green cards.

They let us go. But Alvaro

was going back.

So was his brother Fernando.

So was their sister Sonia. Their mother

did not escape,

and so was going back. Their father

was somewhere in the field,

and was free. There were no great truths

revealed to me then. No wisdom

given to me by anyone. I was a child

who had seen what a piece of polished wood

could do to a face, who had seen his father

about to lose the one he loved, who had lost

some friends who would never return,

who, later that morning, bent

to the earth and went to work.

a. is the correct answer

where are the multiple choice answers?
