crofter from the Oxford Concise Dictionary of National Biography for Sir Walter Raleigh:
"never visited Virginia himself, though the traditional story that potatoes and tobacco were introduced into England in consequence of these attempts at colonisation is probably correct."
There is no mention in Drake's biog of either potatoes or tobacco.
Not sure if this helps exactly!!
I am grateful for these three responses, but they serve to illustrate the dilemma I face... Not easy to guess how informed is the Quiz Setter in question!
