A ________ is the best example of an informational benefit provided by many interest groups.

A) consciousness-raising workshop
B) free T-shirt
C) newsletter
D) health insurance program

Newsletters are often provided by interest groups to inform members and the public about the group's goals, activities, and relevant political news. This type of informational benefit helps to increase awareness and understanding of the interest group's issues and can encourage members to become more involved in advocacy efforts. Consciousness-raising workshops and health insurance programs may also provide informational benefits, but they are typically more focused on education and services rather than advocacy and lobbying. Free T-shirts are an example of a material benefit, which may be provided by some interest groups to incentivize membership or reward supporters.
