How is information deemed task-relevant for analytical tasks?

Information is deemed task-relevant for analytical tasks when it directly addresses the propositions in question. This is essential because the analytical process relies on specific data points or evidence that pertain to the problems being investigated. Relevant information helps in forming conclusions, testing hypotheses, and making informed decisions. If the information does not address the key questions at hand, it may lead to conclusions that are not supported by evidence, thereby impacting the accuracy and reliability of the analysis.

While the other options offer interesting perspectives on elements that may influence analysis, they do not directly define what makes information task-relevant. Independent sources may provide valuable insights, past experiences can inform an analyst's perspective, and physical evidence can support or detract from findings, but these factors do not inherently define how well information aligns with the specific analytical tasks at hand. Thus, the direct relationship of the information to the propositions being examined is what makes it task-relevant.
