【正确答案】The young man is worried because he needs a recommendation letter for his internship application. But he has no time to have one written.
There are two solutions to the problem. The first one is to have Professor John write the letter. And the other solution is to send the application without the letter and hope for the best.
I believe the only good choice here is to ask the professor for the letter, because no corporation would consider a candidate who cannot even submit the required documents such as the recommendation letter. True, the professor is busy. But writing a letter like this is a common chore and would take little time. The student can also remind the professor to write something like how many classes he had with the professor and his performance in the classes.
