The question states "If the table is auctioned on a date that is later than both the date on which the mirror is auctioned and the date on which the vase is auctioned, then which one of the following could be true?" This means that we must put M>T and V>T. In your suggestion of L-S-H-T-M-V, this condition is not met as T is before both M and V.
I hope this helps to clarify. Please let us know if you have any additional questions!
