To determine the reliability of a resource, a speaker should consider the following questions:
1. **Is the information in the source relevant to the topic?** - Ensuring that the information is on-topic is crucial for judgment of its reliability in the context of the presentation.
2. **Is the information in the source written by an expert in the field?** - The credibility of the author is a significant factor in assessing the reliability of any information source.
3. **Is the source readily available online or in libraries should audiences want to learn more?** - The accessibility of a source can contribute to its reliability because if others can verify the information, it enhances credibility.
These questions are more focus-oriented towards the trustworthiness and overall value of the resource, while the other options (such as whether the source is well-known or if the information is too technical) are less directly related to reliability.
