The 'launch pad' of a message is typically realized by a noun phrase and represents the topic or given information. What is this called?

• A. Topic/theme of a sentence
• B. Subject
• C. Focus
• D. End-weight

Answer: (A)

The main idea here is information structure—the part of the sentence that tells us what it is about and what information is already known. The launch pad is the noun phrase that carries the topic or given information, setting the frame for what the rest of the sentence will say. This is different from the subject, which is just the grammatical role performing the action, or from focus, which highlights new or important information, and from end-weight, which concerns how material is distributed for rhythm and emphasis. Since the noun phrase at the start signals the topic or what’s already in play in the discourse, the best label is the topic/theme of a sentence.
