A more thorough explanation:

Definition: Core rights are human rights that are widely accepted around the world. They include freedom from things like torture, arbitrary arrest, and execution without a trial. These rights are included in many human-rights agreements, such as the Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, and the International Covenant on Economic, Social and Cultural Rights.

For example, in most countries, it is considered a core right to be free from torture or other cruel treatment. This means that no one should be subjected to physical or mental pain or suffering as a form of punishment or interrogation. Another example of a core right is the right to a fair trial. This means that everyone should have the opportunity to defend themselves in court and be judged by an impartial judge or jury.

It's important to note that some rights may be considered fundamental within a specific cultural or social context, but not universally recognized. For instance, the right to vote may be considered a fundamental right for citizens in one country, but only a privilege for certain people in another country.
