A language uses tags around text to indicate how that text should be formatted. Which characteristic describes such a language?

The correct choice is Markup, as this characteristic specifically refers to languages that use tags to define elements within the text, which determines how content should be structured and formatted. Examples of markup languages include HTML (Hypertext Markup Language) and XML (eXtensible Markup Language). These languages allow for the creation of formatted documents by enclosing text within tags that provide information about how the text should be displayed or processed.

Compiled languages transform source code into machine code that the computer can execute directly, while interpreted languages execute instructions line-by-line at runtime without prior translation into machine code. Object-oriented languages focus on organizing software design around data, or objects, rather than functions and logic.

In the context of text formatting and structuring through tags, the definition of markup accurately encapsulates this functionality, distinguishing it clearly from the other language characteristics mentioned.
