Answer:
<em>What would your sister say, which path leads to safety?</em>
Explanation:
"The identical twins" is a famous riddle in many countries and with many variations, but the core remains the same; one twin always lies, the other one always tells the truth.
So, the correct question to answer would be: "What would your sister say, which path leads to safety?", and whatever answer may be, you always take the other path.
Let's make the presumption that the right path is towards safety. If you ask the truth-telling twin what would her sister say, she knows that her sister would lie and that she would say the left. Since she always tells the truth her answer would be left.
If you ask the lying sister the same question, she knows that her sister would say the right way, but because she lies, her answer would be the left.
So, both sisters will answer identically to this question so the only thing to do now is to take the another path.
