Question: Read the following statements carefully:
The payoff from ________ in education is so ______ and _______ that it is almost ________ as a predictor of economic change over a five to ten year period.
Fill in the blanks meaningfully, in the above statement, from the following options.
The first three options are eliminated as payoff is usually derived from “investment” and not “expenditure” or “productivity”. If the payoff is “slow and predictable”, it cannot be an irrelevant predictor of economic change. Thus, [5] is eliminated. Also, if data is “erratic”, meaning “inconsistent” or “uncertain”, it is useless in predicting anything.
Hence, the correct answer is option 4.
