Analogy — Fill the missing terms to keep semantic roles parallel: A : Transaction :: Language : B

Introduction / Context:
We must align the roles so the second pair mirrors the first. A “transaction” is a unit or act typically involving money; likewise, “language” is a system used for conversation. Thus, we want A and B that preserve those functional relations.

Given Data / Assumptions:

• A : Transaction — A should be the primary medium/means commonly associated with a transaction.
• Language : B — B should be the primary activity carried out using language.

Concept / Approach:
Map means → act consistently across both halves: money → transaction; language → conversation.

Step-by-Step Solution:

Verification / Alternative check:
Substitute and read: Money : Transaction :: Language : Conversation — both are coherent, primary relationships.

Why Other Options Are Wrong:

• Agreement — is an outcome or document, not the medium; Media — not the primary activity of language.
• Contract — a legal document; Scholar — a person, not an activity.
• None of these — incorrect because a correct parallel exists.

Common Pitfalls:
Confusing instruments, outcomes, and participants; the task needs the natural medium and activity.

Final Answer:
A. Money, B. Conversation
