Magpie SC from GMAT PREP2

by Giorgio » Sat Dec 26, 2009 3:28 pm
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 country have been attacked by the birds.

a) same
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 birds.
c) by the time they reach adulthood, 98 percent of men and 75 percent of the women born in the country had been attacked by the birds.
d) 98 percent of the men and 75 percent of the 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 birds

OA is : C

I don't understand what's wrong with E , and why C is correct ? is it possible that They could refer back to Magpies ?

magpie modifies attacks so they can't refer to birds, hence C sounds correct to me.

I just checked on my gmatprep - you have a small typo- in c, it should be past tense- "by the time they reached"

hope that helps :) now it should make sense.
