请教Tina老师这样一道题： The first detailed study of magpie attacks in Australia indicates that by the time they had reached adulthood, 98 percent of men and 75 percent of women born in the country have been attacked by the birds. A. by the time they had reached adulthood, 98 percent of men and 75 percent of women born in the country have been attacked by the birds B. by the time they reach adulthood, 98 percent of men and 75 percent of women, who were born in the country, had been attacked by the birds C. by the time they reached adulthood, 98 percent of men and 75 percent of women born in the country had been attacked by the birds D. 98 percent of men and 75 percent of women that were born in the country were attacked by the birds by the time they reach adulthood E. 98 percent of men and 75 percent of women who were born in the country, by the time they reached adulthood had been attacked by the birds 这道题答案是C，我错选了D。原因是因为C中离they最近的名词是男人和女人（magie attacks是袭击，magie感觉是修饰成分，而且还是单数），因此我觉得C太容易让人误认为they指代的是人而不是鸟了，D虽然繁杂一点，但是they可以很好地指代在鸟上，不会产生歧义，因此选了D，请老师解答，谢谢！
