The correct answer is B) the rise of partisanship in Congress.
The scrutiny of the nominated judges mirrors the rise of partisanship in Congress.
Many politicians and experts think that the scrutiny of the nominees to federal judges is important because of the level of responsibility they are going to have in their positions. So much has been discussed in this regard, including in the US Congress, where legislators have emphasized the importance of having exemplary judges in the Supreme Court that honor the principles of the judicial branch.
