"Rule of Law Index" is released by which of the following ?

Says Amnesty International prepares and publishes reports on human rights worldwide, showing Amnesty is a publisher of research/reports.

A student could check Amnesty's publications list (or website) for whether the specific 2018 'Rule of Law Index' appears among its releases.

Gives a clear definition of 'rule of law' as a legal/political concept, indicating the type of topic a rule-of-law index would cover.

Use this to identify which organizations typically produce comparative 'rule of law' indices (legal/research bodies) and then see if Amnesty is among them for 2018.

Describes an example index (Financial Secrecy Index) and explicitly names its producer (Tax Justice Network), illustrating that many indexes are produced by specialized organizations or networks, not necessarily by human-rights NGOs.

Compare known index producers' names with the publisher of the 'Rule of Law Index' (e.g., check the index front matter or announcement) to see if Amnesty is the publisher.

Mentions PISA as a worldwide index produced by a specific organization (OECD), reinforcing the pattern that indices are typically tied to particular institutional publishers.

A student could look up who officially publishes the 'Rule of Law Index' (publisher attribution) for 2018 and compare with Amnesty's publication record.

Shows Amnesty conducts investigations and reports on specific human-rights issues (e.g., Guantanamo), indicating its focus and typical subject-matter for reporting.

Use Amnesty's typical report themes to assess plausibility — if the 'Rule of Law Index' is a broad comparative index rather than themed human-rights reports, that may suggest a different publisher; then verify by checking the index's publisher.
