query: What are the three most consumed cereal grains?
passage: Cereal
Maize, wheat, and rice together accounted for 89% of all cereal production worldwide in 2012, and 43% of all food calories in 2009,[11] while the production of oats and triticale have drastically fallen from their 1960s levels.
passage: Cocoa bean
The three main varieties of cocoa plant are Forastero, Criollo, and Trinitario. The first is the most widely used, comprising 80–90% of the world production of cocoa. Cocoa beans of the Criollo variety are rarer and considered a delicacy. Criollo plantations have lower yields than those of Forastero, and also tend to be less resistant to several diseases that attack the cocoa plant, hence very few countries still produce it. One of the largest producers of Criollo beans is Venezuela (Chuao and Porcelana). Trinitario (from Trinidad) is a hybrid between Criollo and Forastero varieties. It is considered to be of much higher quality than Forastero, has higher yields, and is more resistant to disease than Criollo.
