1. Who discovered America?
The correct answer is Christopher Columbus. He was an Italian explorer who set sail in 1492 with the goal of finding a new route to Asia, but instead, he arrived in the Americas.

2. Who has turned off the washing machine?
To answer this question, we need more information or context. If it is a specific situation, such as a family or a group of people living together, we need to know who was present at the time and who had access to the washing machine. Without this information, it is not possible to determine who turned off the washing machine.

3. Which of you is Susan?
This question is asking for identification. If you are Susan, you can simply say, "I am Susan." If someone else is being asked this question, they can respond with their own name instead of Susan. The important thing is to clarify who Susan is among the people being addressed.

4. Which of them works at the factory?
Similarly to question 2, to answer this question, we need more information or context. We need to know who "them" refers to and who is being considered in relation to working at a factory. Without this information, it is not possible to determine which person works at the factory.

5. Which of the flowers smells nice?
To identify which flower smells nice, we need to smell each flower individually. By using our sense of smell, we can determine which flower has a pleasant fragrance. It is important to remember that people's preferences may vary, so what smells nice to one person may not be the same for another person.
