Singapore Queries-la!

A few things that I wonder about in Singapore:

a)How are the trains from different lines synchronised at MRT interchange stations to arrive in a manner that you get out off one to immediately walk into another?
b)How come the trees are all to a uniform trim & how come you don’t see them being trimmed?
c)How come a place so close to the equator manages to remain pest-free?
d)Precisely when in history did the national religion evolve to being shopping?
e)What did Orchard road look like before the malls were invented?
f)How come all sense of Singapore discipline breaks down the minute you enter Little India?
g)How does Mustapha do it – keep so many things under one roof at such prices?
h)When did the ‘can-la’ patois actually start?
i)Why did they build high rise condo’s with re-inforced concrete bomb shelters in each of the apartments? Further, in the eventuality of their actual use, how did they intend to get the people cooped up inside, down from the 40th floor, assuming that everything else got wiped out?
j)Why do they bother to publish such a thick newspaper?
k)How come there aren’t so many DVD rental places?
l)Do they seriously need to publish everything in 4 languages?
