St. Kilda, a tiny cluster of islands and sea stacks perched in the North Atlantic $40$ miles west of North Uist, was occupied for more than $4,000$ years. A small community once huddled around the curve of Village Bay on Hirta, the largest island. Sheep grazed steep slopes all around. Modest crops of barley, oats, and potatoes were grown in raised beds, where thin soil was carefully augmented with applications of mineral-rich seaweed. Winter storms, rolling unchecked across thousands of miles of open ocean, struck the islands with almost unimaginable ferocity. In $1852, 36$ islanders— roughly a third of the population at that time—chose a long and arduous journey to Australia over remaining on St. Kilda. Many perished at sea.

Which of the following, if true, would significantly strengthen the conclusion in this paragraph?
