First I think it is one of the gmat prep Q, so definetly gmat like. Let us analyse:
Thursday : 5 specially ordered shipment
Friday : Only building supplies
Sat/Sun : closed no work
M/T/W : No idea what happened.
3 of the 4 to Truax were building supplies, on friday only building supplied were sent but not vice versa.
A: What we know for sure is one of the shipment can not be sent on friday. But it can be sent on M/T/W and needn't be special.
B: There is no connection between specially ordered and building shipment other than they were sent on different days.
C: Same as A.
D: What we know for sure that on monday only building material were shipped, but it doesn't mean all building supplies were on friday. So wrong.
So IMO E.
Charged up again to beat the beast
