For women, the most accurate predictor of their length of life is

A. biological age.
B. chronological age at menopause.
C. level of physical activity.
D. nutritional intake over the past decade.

Having already found differing answers to these questions online, I think you better use the ones in your text book.

i don't have one that's why im so confused because i do online schooling and i don't have text books

Aww! Come on! You can't learn anything without a book or at least recommendations for online information.

Drop these classes, NOW! You are not getting an education! You are being cheated!
