Archaeologist Petra Vagilova, anthropologist Xinyi Liu, and their colleagues investigated the domestication of farm animals in China during the Bronze Age (approximately 2000 to 1000 BCE). By analyzing the chemical composition of the bones of sheep, goats, and cattle from this era, the team determined that wild plants made up the bulk of sheep's and goats' diets, while the cattle's diet consisted largely of millet, a crop cultivated by humans. The team concluded that cattle were likely raised closer to human settlements, whereas sheep and goats were allowed to roam farther away.

Which finding, if true, would most strongly support the team's conclusion?

Question

Accepted Answer

Analysis of the animal bones showed that the cattle's diet also consisted of wheat, which humans widely cultivated in China during the Bronze Age.

Answer

Further investigation of sheep and goat bones revealed that their diets consisted of small portions of millet as well.

Answer

Cattle's diets generally require larger amounts of food and a greater variety of nutrients than do sheep's and goats' diets.

Answer

The diets of sheep, goats, and cattle were found to vary based on what the farmers in each Bronze Age settlement could grow.
