Could you explain how you get the answer to this question please;

Ishmael, Ravi, Ed, Lucy and Paddy all traveled by train to Wembly to watch a football match.

Paddy arrived before Ishmel, Lucy and Ed.
Lucy left home at 6.00am.
Ravi traveled further than Ed.
Ishmael left after breakfast and got there second.

If these statements are true, only one of the sentences below MUST be true.

Which one?

A. Lucy lives furthest away.
B. Ravi took longer to get there than Ed.
C. Lucy spent the morning sightseeing in London.
D. Paddy arrived first.
E. Ravi left home before Lucy.

E. Ravi left home before Lucy.
D. Paddy arrived first
because
Paddy arrived before Ishmel, Lucy and Ed.
and
Ishmael left after breakfast and got there second.

If Paddy arrived before Ismael, who got there second, then Paddy must have arrived first

you don't have to prove or disprove all the statements -just find the one that HAS to be true ie because we know Ishmel was second and that Paddy arrived before Ishmel then the statement that Paddy was first has to be true.

Ravi may have taken longer to get there than Ed but we haven't got enough info to tell us.
