There are a number of issues with this question – one of which, I should mention, was pointed out to me by someone else.
One issue is the wording: "Name one of the three rivers that flow into the Solent, apart from the Test." On reading this, I got the impression that there were three rivers apart from the Test that flowed into the Solent.
That wouldn't really have been a problem, because you only needed to know one of them, and well done if you even knew of two. But the other issue is potentially more serious: it is that unless I'm missing something, none of these rivers flows into the Solent. They all flow into Southampton Water.
In fact, the principal river that flows into the Solent is the Medina – which (as most readers of this website will know) is the principal river on the Isle of Wight.
Because we were given the Test, I reckon that most experienced quizzers would have gone for the Itchen. So no harm done, I suppose – unless someone had answered "the Medina". Or indeed, "Southampton Water", which (according to Wikipedia) is a tidal estuary. Does that make it a river? Apparently not – an estuary is "a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it ... a transition zone between river environments and maritime environments". I wouldn't have known this if anyone had given this answer on the night – and I wonder how many of the actual question askers would have known?
The Solent, by the way, is a strait.
