Step 1: Break Down the Problem

We need to identify the large land mass from the given options that is not a part of a sovereign state. This involves analyzing each option to determine its political status.

Step 2: Relevant Concepts

• A "sovereign state" refers to a political entity that is represented by one centralized government that has sovereignty over a geographic area.
• We will evaluate each of the provided options to determine if they are associated with a sovereign state or not.

Step 3: Analysis and Detail

1. Siberia: This is a region in Russia, which is a sovereign state.
2. The Arctic: This is an ocean region that includes land areas owned by various countries, so it's not just a singular land mass but rather shares sovereignty among several states.
3. Greenland: Although largely autonomous, Greenland is part of the Kingdom of Denmark, hence it is associated with a sovereign state.
4. Newfoundland: This is a province in Canada, which is a sovereign state.
5. Antarctica: This continent is governed by the Antarctic Treaty System, which preserves the continent for scientific research and prohibits military activity, making it a unique area with no sovereign state claiming it exclusively.

Step 4: Verify and Summarize

Upon analyzing all five options, it is evident that Antarctica is the only large land mass that does not belong to any sovereign state, as it operates under international treaties that prevent territorial claims.

Final Answer

Antarctica is the only large land mass not part of a sovereign state.
