Question

read the meanings of the word fold, then read the sentence.
definition 1. n., a crease in fabric or a piece of paper
definition 2. v., to bend
definition 3. n., a group of people with common beliefs
definition 4. v., to incorporate one food ingredient into another
what is the meaning of fold as it is used in this sentence?
when making cake batter, it is important to fold the flour into the butter before adding the rest of the ingredients.
(then there are boxes labeled definition 1, definition 2, definition 3, definition 4)

Explanation:

The sentence is about making cake batter and incorporating flour into butter. Definition 4 is "v., to incorporate one food ingredient into another", which matches the context of mixing ingredients in cooking. Definitions 1 (crease in fabric/paper), 2 (to bend), and 3 (group of people) don't fit the context of combining food ingredients.

Answer:

Definition 4: v., to incorporate one food ingredient into another
