On the Wikipedia 'History' article, describe how historians ensure the accuracy and reliability of their research. Additionally, identify the two main types of historical evidence they use, providing one example for each type as explained in the 'Methods' section of the article.
Navigate to the Wikipedia 'History' article (https://en.wikipedia.org/wiki/History). Use the table of contents to go to the 'Methods' section. Within the 'Methods' section, locate the 'Sources and source criticism' subsection. Identify and summarize the process historians use to ensure accuracy and reliability of sources, including its typical first step. Identify and describe the two primary types of historical evidence. Provide one distinct example for each type of historical evidence. Synthesize the findings into a concise answer.
The explanation of how historians ensure accuracy and reliability accurately states they use 'source criticism' to analyze and evaluate source information. The explanation of source criticism accurately states its typical first step is 'external criticism' to evaluate authenticity. The two primary types of historical evidence are correctly identified as 'Primary source' and 'Secondary source'. A valid example for a 'Primary source' is provided (e.g., official documents, letters, diaries, eyewitness accounts, photographs, audio/video recordings, artifacts, or fossils). A valid example for a 'Secondary source' is provided (e.g., a source that analyzes or interprets information from other sources, or a historian's text based on historical documents).
