try this:
Service B&C are good buddies. They travel together until Avenue
M. Then they will say good bye to each other for a while.
So after B & C went to their routes, they meet back at Road
N. From then on they will travel together.
Upon reaching expressway O, Service A, who starts at the same
interchange as B & C, joins them on their journey.
Halfway through the journey, A & B needs to go to the
''washroom''. After A & B came out of the ''washroom'',
the 3 services carry on their journey on expressway P
So they travelled on the expressway till they reached Avenue Q
where A will say ''goodbye'' to B and ''See You Later''
to C.
After saying good bye to A, B&C carry on their journey till
they reach Avenue R, there B will say good bye to C and will carry
on its journey on expressway P to its looping point
A and C meets each other again at Avenue S for a short while
then they will proceed on to their respective interchanges.
Identify Service A B & C, Avenues M, R, Q and S. Expressway
O and P, and Road N and the ''washroom''
This should be quite easy.
Not sure if anyone noticed. but i missed out KTPH part for
858(B) totally slipped my mind.
