Hi,

Schedule 4 in Question 1 and Schedule 3 in Question 2 are both missing semicolons.  Can you please confirm this a typo or does this mean the two events happen at the same time? 

E.g.: Does "T1:w(Y) T2:w(X)" mean "T1:w(X)" first, then "T2:w(X)" or that these two happen at the same time?

Thanks,

Nelson
