The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Why is it important that judges are appointed and that they cannot be removed from office unless impeached?
It is very important because these judges must decide on very difficult and important decisions in the United States. That is why their morals and ethics must be second to none.
That is why the President of the United States must consider positive and negative aspects when deciding who to nominate for a Supreme Court justice. Because they are going to be there for life.
The President and the Senate, which confirms the appointment, must consider the experience of the judge, its reputation that must be intact, its knowledge, its moral, ethics, and values, its commitment to the country, its mental and physical health.
