Here comes yesterday’s question:
Of the listed stars, which of the following has the longest life expectancy?
A. The Sun
B. Betelgeuse
C. Proxima Centauri
D. R136a1
This was…
SpoilerC. The Sun has about 10-11 billion years total, Betelgeuse has about 10 million years and is due to explode very soon (in astronomical terms), R136a1 has around 3 million years, but as a red dwarf star, Proxima Centauri is expected to live for hundreds of billions to trillions of years.
Here comes today’s question:
The Voyager probes have been in service for just shy of 45 years now. How far away is Voyager 1?
A. 10.86 light minutes
B. 45.3 light years
C. .0050 parsecs
D. 21.5 light hours

oooookay, I'm not sure if I'm allowed to participate in this, but these kind of questions are speaking to me xD Actually, I was already tempted yesterday xD I think I give you this answer and you can decide whether I'll take part or not :3
SpoilerIt's D
and it's the only plausible option here. I don't know the exact value, but I can discount all other options here
Sun <> Earth avg id distance of 8.3 light mins
Sun <> Pluto avg distance is around 4 light hours
Sun <> Next Star distance is around 4 light years (ly).
Distance of A would be far too little. B far too large, actually 45.3 ly in less than 45 years - this would be even faster than light itself xD and for C: 0.005 parsec = 3.26 ly/parsec * 0.005 parsec > 100 light hours - this is closer but our chemical propulsion systems aren't quite that efficient.

@Astral Soul Gah! I think you're right. My calculations were based on an obviously faulty estimation of the distance between Earth and the sun, so my answer is off by roughly a factor of 60.
