Rearrange the parts to form a meaningful sentence: P: lay outside her existing life Q: she knew that the answer R: somewhere in the back of her mind S: to her questions about life

The correct sequence is RQSP: 'Somewhere in the back of her mind she knew that the answer to her questions about life lay outside her existing life.' R sets the location (back of her mind), Q introduces what she knew, S specifies the answer relates to her questions, and P concludes where it lay.
