* What is *written* in Greek? This refers to text written in the Greek language. To answer this, I'd need more context. What text are you referring to?
* What is *something* in Greek? This asks for the Greek word for something. Again, I need to know *what* something you're asking about. For example, "What is 'hello' in Greek?"
* What is *contained within* Greece? This refers to the geography, culture, or people of Greece. The answer would be a very broad description of the country and its features.
Please clarify your question.
