Which of the following could be a possible disadvantage of joining the European Union? Members must follow strict rules set by the European Union Wealthier countries pay more than poorer countries Open borders can cause problems All of the above 1 point

The answer is "All of the above."<br /><br />Here's why:<br /><br />* **Members must follow strict rules set by the European Union:** While these rules are often designed to benefit all members, they can sometimes be perceived as inflexible or burdensome, especially for countries with differing priorities. Loss of some national sovereignty in decision-making is a key concern.<br /><br />* **Wealthier countries pay more than poorer countries:** This is designed to help less developed nations catch up, but it can be a source of resentment for wealthier nations who feel they are disproportionately contributing.<br /><br />* **Open borders can cause problems:** While free movement of people is a benefit for many, it can also lead to concerns about increased competition for jobs, strain on social services, and security issues.<br />
