I want to know the answer to the following question:
What kind of connection is provided on the iPod Shuffle for both audio output and file transfer?
All the background I'm provided with is that "The second-, third-, and fourth-generation iPod Shuffle uses a single 3.5 mm minijack phone connector which acts as both a headphone jack and a data port for the dock.". Is that enough to answer the question?
Answer: yes
