why might lower - income groups not participate more in the interest group system?\nlack of awareness and…

Brief Explanations:

Lower - income groups may face several barriers. A lack of awareness and information about the interest group system can prevent them from knowing how to participate. Political apathy, which could be due to past experiences of feeling unheard or a sense that their participation won't make a difference, can also play a role. Limited time and resources (e.g., they may be working multiple jobs just to make ends meet and can't afford to spend time on interest - group activities) are significant factors. A strong interest in participating would likely lead to more participation, so this option is not a reason for non - participation.

Answer:

A. Lack of awareness and information, B. Political apathy, D. Limited time and resources
