Last Year Kanya Immigrated to This Country from Thailand

Last year Kanya immigrated to this country from Thailand. Although she now feels comfortable speaking English in everyday conversations,she still has only a limited knowledge of English vocabulary,and she struggles with some of the English language's complex grammatical constructions. Near the end of the school year Kanya must take the same standardized set of achievement tests that her classmates take. For Kanya,we might reasonably suspect that the tests will:

A) Have low practicality.
B) Have low reliability.
C) Be culturally biased.
D) Have high predictive validity.
