Answer 1

Answer:

James Lind, a Scottish doctor, is usually given the credit for discovering in 1747 that scurvy, the disease that plagued many early European seafarers, could be prevented through the consumption of citrus fruits, even though he had no idea what the protective substance was.

But according to the controversial book, ‘1421: the year China discovered the world’, written by retired submarine commander Gavin Menzies and first published in 2002, this is an ethnocentric judgement. The book suggests that earlier, long distance Chinese voyagers were almost entirely successful in preventing the development of scurvy among their crews.
