Answer
which source would be the most reliable to validate a claim?

2. a journal
3. a magazine
4. the internet

Answer:

Newspaper is the most reliable source of information to make a claim valid.

Explanation:

A newspaper is always considered as the authenticated source of information. A news that is published in a newspaper is always regarded as a valid news because it is published from a government authorised and renowned newspaper publishing house. For example, if we want to claim a certificate or an authorisation, it will be considered acceptable if we publish it in a newspaper. So it is the most reliable information source to make a valid claim.
