An atom emits yellow light when an electron makes the transition from the n = 5 to

Question:

An atom emits yellow light when an electron makes the transition from the n = 5 to the n = 1 level. In separate experiments, suppose you bombarded the n = 1 level of this atom with red light, yellow light (obtained from the previous emission), and blue light. In which experiment or experiments would the electron be promoted to the n = 5 level?
