Answer: The word "formulas" can have different meanings depending on the context in which it is used.
One common meaning is a prescribed set of instructions or a standard method for performing a task or solving a problem. For example, in mathematics or science, a formula can refer to a specific equation or set of equations that are used to calculate a result or describe a relationship between variables.
In another context, "formulas" can refer to a set of words or phrases used in a specific way to convey a particular meaning or message. For example, in the context of marketing or advertising, "formulas" can refer to a set of techniques or strategies used to create a successful campaign or brand image.
Overall, "formulas" typically refer to established, often standardized methods or techniques for accomplishing a specific task or achieving a specific outcome.
Explanation: In this context, "formulas" most likely refers to different phrasings or formulations of commitments or promises that could be used to create an agreement between the US and Japan. These "formulas" could potentially be used to reach a mutual understanding between the two countries about their respective interests and commitments, without necessarily committing to any specific policy or action.
The sentence "And he tried out on Nomura various formulas committing Japan to peaceful courses of action in the Southeast Asia region" suggests that the person mentioned in the preceding sentences was testing different ways of phrasing the commitments that Japan might make regarding their actions in Southeast Asia. This would be done with the goal of finding a formulation that would be acceptable to both parties and could serve as a basis for further negotiations.
