Which answer corrects the error in capitalization?
the large land mass in the northern half of michigan is called the upper peninsula.
a. michigan
b. land
c. upper
d. peninsula

I would think that it would have to be peninsula for Michigan is a place so it is capitalized Land is not a place or proper Upper isnt either and peninsula just doesnt seem like it would be capatolized.

Peninsula corrects the error in capitalization. This is because, the law of English says that any noun should be Capitalized.

If you give me the two excerpts to compare, i would be able to you : )
