The passage given below is followed by a set of questions. Choose the most appropriate answer to each question.
Descendents of the Maya living in Mexico still sometimes refer to themselves as 'the corn people'. The phrase is not intended as a
metaphor. Rather, it's meant to acknowledge their abiding dependence on this miraculous grass—the staple of their diet for almost nine
thousand years. Forty percent of the calories a Mexican eats in a day come directly from corn, most of it in the form of tortillas. The very
substance of the Mexican's body is, to a considerable extent, a manifestation of this plant.
For an American like me, (growing up linked to a very different food chain, yet one that is also rooted in a field of corn) not to think of
himself as a corn person suggests either a failure of imagination or a triumph of capitalism. Or perhaps, a little of both. It does take some
imagination to recognize the ear of corn in the Coke bottle or the Big Mac.
You are what you eat, it's often said, and if this is true, then what we mostly are is corn - or, more precisely, processed corn.
After water, carbon is the most common chemical in our bodies - indeed, in all living things on earth. During the process of
photosynthesis, the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the
simple organic compounds that stand at the base of every food chain.
Scientists can tell that a given carbon atom in a human bone owes its presence there due to corn, on the basis of the isotope of that atom.
Corn takes in relatively more of the carbon isotope called carbon 13 rather than the more common carbon 12. The higher the ratio of
carbon 13 to carbon 12 in a person's flesh, the more corn has been in his diet - or in the diet of the animals he or she ate. (As far as we're
concerned, it makes little difference whether we consume relatively more or less carbon 13.)
One would expect to find a comparatively high proportion of carbon 13 in the flesh of people whose staple food of choice is corn -
Mexicans, most famously. Americans eat much more wheat than corn - 114 pounds of wheat flour per person per year, compared to 11
pounds of corn flour. The Europeans who colonized America regarded themselves as wheat people, in contrast to the native corn people
they encountered. But carbon 13 doesn't lie, and researchers who have compared the isotopes in the flesh or hair of Americans to those
in the same tissues of Mexicans report that it is now we Americans who are the true people of corn. Compared to us, Mexicans today
consume a far more varied carbon diet: the animals they eat still eat grass (until recently, Mexicans regarded feeding corn to livestock as
a sacrilege); much of their protein comes from legumes; and they still sweeten their beverages with cane sugar.
So that's us: processed corn, walking.

2) He is unaware of the fact that corn is used to make fast food such as Coke and Big Macs.
3) Coke and Big Macs contain a substantial amount of processed corn, but not in a visually obvious form.
4) The capitalist economy has succeeded in hiding the role of corn in popular foods such as Coke and Big Macs.
