You need the answers "by" today.
;)

First, Ted came up with 8 different theories as to where
Salim may be. He discussed all 8 of the theories until he arrived to the one which was
correct. The coriolis effect, and how things around earth invisibly go from one point to
another, affecting everything around us as a domino effect. Then, he put it all together
and saw that the Barrick's building was "just around the corner" and remembered that
Salim was totally into really tall buildings. Ted then remembered that such building was
to be demolished, so everyone ran towards Barricks and found Salim on the 21st floor: He
had indeed gone up there to the top to take pictures, but got stuck trying to get down
and was shortly about to get killed  by the demolishing truck if Ted had not figured it
all out.
