In social science research, "highest education level

[BTGmoderatorDC]

In social science research, "highest education level attained" would refer to the most advanced grade or degree achieved by an individual-for some individuals, it may be a grade in grade school, and for other individuals, it may be a Bachelor's Degree, a Master's Degree, or Ph.D. (which is considered the highest education level). A recent study has shown a strong correlation between highest education level attained and proficiency in chess. Another result, studied at many points throughout the 20th century, shows a marked positive correlation between highest education level attained and income level.

Assuming the statements above are true, what conclusion can be drawn from them?


A) If one practices chess enough to raise one's proficiency, one has a good chance of raising one's income level.

B) It is possible that a person who has attained only a sixth grade level of education could earn more than a person who has a Ph. D.

C) If Jane has a Ph. D., and Chris has not finished his undergraduate degree, then Jane will usually beat Chris in chess.

D) The average salary for people who have completed three-year Master's Programs is higher than the average salary of people who have completed two-year Master's Programs.

E) An individual's proficiency at chess rises consistently during that individual's years of school, and levels off once that individual has finished her years of formal education.
