If you're following the protocol many of us do,
1. Orientation
2. All the "If" questions
3. Everything else
then you have a lot of previous work at your disposal by the time you get to Q15.
Here's what I had after doing 14, 16, 17
Q14:
R ( QT, U ) | S
S R Q T | U
Q16
U T S R | Q
U Q T R | S
Q17
S R Q T | U
S Q T U | R
Q T S U | R
A) Have we seen RS? Nope, keep this.
B) Have we seen SQ? Yup, in Q17
C) Have we seen ST? Nope, keep this.
D) Have we seen TR? Yup, in Q16
E) Have we seen UT? Yup, in Q16
So you'd only need to do plug and chug with (A) and (C).
