Alex is delivering a eulogy at his grandmother's funeral. He notices that his mother, who is sitting in the front row, looks very upset. He feels his heart racing as he begins to speak. What type(s) of interference is Alex experiencing, and how should he proceed?
1) It's an internal interference caused by seeing his mother upset in the front row. He should pause and take a few slow, deep breaths to calm his heart rate before starting to speak again.
2) It's an internal interference, and he should ask someone else to deliver the eulogy for him.
3) It's both internal and external. He should take a few moments to comfort his mother before speaking.
