college-educated women and women living in the South and West to be significantly more likely to be using supplemental hormones as women living in the Northeast and Midwest.
(A) college-educated women and women living in the South and West to be significantly more likely to be using supplemental hormones as women living
(B) college-educated women and women living in the South and West as significantly more likely to use supplemental hormones than if they are living
(C) college-educated women and those living in the South and West being significantly more likely to use supplemental hormones than if they lived
(D) that college-educated women and women who live in the South and West are significantly more likely to be using supplemental hormones as were women that lived
(E) that college-educated women and women living in the South and West are significantly more likely to use supplemental hormones than women living
(D) that college-educated women and women who live in the South and West are significantly more likely to be using supplemental hormones as were women that lived
(E) that college-educated women and women living in the South and West are significantly more likely to use supplemental hormones than women living
"results have shown that" is necessary, we can eliminate A B C.
If we continue to read the choices left we'll notice some errors in D:"more likely to be using" VS "more likely to use"(more clear) and "more (...) as" VS "more (...) than" (the correct idom). E is the correct answer
