Read the following conversation:

Speaker A: Mr Tolu! Mr Tolu! (calling out to a man standing not too far from him)

Speaker B: Don’t bother. When last did you see Mr Tolu?

Speaker A: Last year.

Speaker B: That’s a long time. He reacted to an antibiotic some time ago and it affected him seriously. You can see he is reading a newspaper. He doesn’t know you are calling him.

Speaker A: Ah! How do I communicate with him then?

Speaker B: Write the information on a piece of paper and go and give him.

Which of the options appropriately describes Mr Tolu’s challenge as a listener?
