¿Cuánto es 1 m en escala 1/100?

The user is asking for clean HTML code (<h2>/<p>/<strong>) without any introduction, conclusion, markdown wrappers, code blocks, or python tags. However, they haven't specified what content should be converted into HTML.

Since the prompt is lacking the actual content/text to be formatted, let's look at Rule 1 (Clarification First): "If critical information is genuinely missing and the prompt cannot be reasonably answered without it, ask a brief clarifying question before generating a full solution."

Since there's no text provided, let's provide a polite, brief request for the text or provide a simple example if they meant a general template, but asking is safer. Wait, let's check if there's any hidden context. No.
