SAP智力題 3-way puzzle ★★★★★★★

This is a variation of 2-way puzzle.
You are at an intersection, and there are 3 ways, 2 ways lead to death, 1 way leads to life. Fortunately, there is a god at the intersection. If he likes you, he speaks truly, otherwise he speaks falsely. You can ask only one yes-no question. How you find out which way leads to life? Be noted, if your question can not be answered in yes or no, he will keep silence.
