官方解說：
The "because" structure of the sentence indicates that the first part of the sentence gives a reason for a conclusion reached in the second part of the sentence. The conclusion is that economists have been unable to provide governments with a "method for predicting unemployment rates." Of the choices given, "precede" works best in the blank in spelling out a reason for this conclusion: information (currently lacking) about what indicators usually precede a rise or fall in employment would certainly helpful for predicting unemployment rates.
Thus the correct answer is precede.
