Answer:
Reliable; current.
Explanation:
A reliable source is an information source that is unbiased, trustworthy and reliable. Also, a reliable source is typically backed up by evidence from various information channels and should be accurate.
In order to validate a reliable source, it is necessary that the information provided is checked against other credible sources to verify its accuracy.
This simply means that, if you got an information (data) from any source such as newspaper, website, television, books, radio or anywhere else, you should confirm the credibility and reliability of these information by verifying from one or more sources. Therefore, if the information gotten from a new source is in tandem or accordance with what you find elsewhere and are recent with respect to time of publication (current), then that information is accurate, reliable and credible
Hence, making certain that a research source is reliable and current will improve the quality and usefulness of the data you use.
