DAILY TRAIN SCHEDULE
Train X
Scheduled Departure Station S at 7:08 (EST)*
Scheduled Arrival Station T at 8:10 (EST)
The table above shows the morning schedule for train X . If Juan took train X on Monday morning, did he arrive at station T on schedule?
(1) Juan arrived at station T on Monday morning 1 hour and 2 minutes after he left station S .
(2) Juan arrived at his office at 8:30 (EST) on Monday morning, which was 20 minutes after he arrived at station T .
B.
From (1) we can not conlude whether the train departed from Station S on schedule.
Old topic that I found , I feel it needs a bit of discussion
We have been able to prove that A is not sufficient , because we cannot assume that the train left Station S on time .
Which is very correct , we shouldn't assume anything, right?
For statement B why are we assuming that Train arrived at station T the same Monday morning that it left station S.
It is highly impractical but not entirely impossible that due to a calamity the train was stuck in between and it took 7 days to repair the tracks and only then the next Monday morning the train arrived at station S,coincidentally at 8:10 EST.
I think we also shouldn't assume that 8:10 Monday arrival at T is the same Monday morning it left S , it could be the next week Monday morning or even after 2 weeks.
No where in Statement B does it say Juan arrived at T the
same Monday morning it left S.
Please tell me why is this scenario not possible at all.
I think there is a small scope for argument that B too is insufficient based on the logic above.
I think C would be more accurate , because if Juan arrived at 8:10 at Station T and it took 1 hour 2 minutes then Train arrived at T the same Monday morning it left S .
I vote for C.
Hope others will agree.
The questions asks: "did he arrive at station T on schedule?" We know that Scheduled Arrival at Station T is at 8:10 (EST). From (2) we get that he arrived at Station T at 8:10 (EST). Thus (2) is sufficient.
