Relevance means usefulness of information based on your present needs. You
heard over the radio that a new company is selling a very effective hair grower.
Would that information be relevant to you?

Answer:

The relevance of information is determined by its usefulness in addressing one’s current needs or interests. In the context of hearing about a new company selling a highly effective hair grower over the radio, the relevance of this information would depend on whether you have an interest in hair care, specifically in promoting hair growth. If you are someone who is concerned about hair loss or desires to enhance hair growth, then the information about the new product could indeed be relevant to you. However, if you do not have any concerns related to hair care, then the information may not be relevant at that particular moment.
