Each year, the United Nations Development Program (UNDP) rates a nation’s development according to the Human Development Index (HDI). The HDI measures the human development in a country based on certain factors. Which is a factor the index uses?

birth rate
education
gross national income
assessable tax base

My guess is D. Is that correct?

http://en.wikipedia.org/wiki/Human_Development_Index

life expectancy, education, and income indices

Im still confused But ill go with B.
The questions wording is a bit off it think...

The Education Index is certainly one measure the HDI uses.

Okay, thank you Writeacher :)

I had to read and reread that question more than once! "Which is a factor the index uses?" <~~"a factor" means one factor out of several. It took me a bit to "get" that!!

You're welcome!

No, the correct answer is B) education. The Human Development Index (HDI) measures a nation's development based on several factors, including life expectancy, education level, and income. While birth rate and gross national income are important aspects of development, they are not specifically considered in calculating the HDI. Assessable tax base is not a factor used in the calculation of the HDI.
