One of the threats of strict or strong partisanship is that it could lead to effective conflict. This is because when individuals or groups are strictly partisan, they are often unwilling to compromise or consider alternative viewpoints. This can lead to conflict as each side fights to have their views and policies implemented, often to the detriment of the overall group or society.

Increased participation is not necessarily a threat of strong partisanship. While it is true that strong partisanship can motivate individuals to become more politically active, this is not inherently a negative outcome.

Increased apathy could potentially be a result of strong partisanship, particularly if individuals feel that their views are not being represented or that the political process is dominated by partisan interests. However, this is not a direct threat of partisanship itself, but rather a potential consequence of a political environment dominated by strong partisanship.

A decrease in ideological thinking is not a threat of strong partisanship. In fact, strong partisanship often involves very rigid ideological thinking, as individuals or groups adhere strictly to a particular set of beliefs or policies.

So, the most accurate answer to the question would be "effective conflict."
