Indeed, your answer is equally correct. Please report this sentence next time you encounter it (reporting sentences ensures that the course authors will see the problem — if you just write about the problem in the comments, it might be missed, because there're many different comments every day).
"Хлеб" is an inanimate masculine noun, so its accusative form is the same as its nominative form. In general, for animate masculine and neuter nouns, the accusative form matches the genetive form, but for inanimate masculine and neuter nouns, the accusative matches the nominative. Feminine nouns have their own accusative form and are not divided into animate and inanimate categories.
