Which pronoun correctly completes the elliptical clause?

typically, jasmine arrives earlier than

a.
us

b.
we

Typically, Jasmine arrives earlier than A. us.
The correct answer is A.

This is because you need to use an objective pronoun - the word us is an object of this sentence, and the pronoun we can only be used as a subject. Just substitute the last pronoun with I (subject pronoun) or me (object pronoun). You'd definitely say - She arrived earlier than me (and not than I), and thus you know it is an object, not a subject.

"Oh, God", he thought, "what a strenuous career it is that I've chosen! Travelling day in and day out. Doing business like this takes much more effort than doing your own business at home, and on top of that there's the curse of travelling, worries about making train connections, bad and irregular food, contact with different people all the time so that you can never get to know anyone or become friendly with them. It can all go to Hell!"

"Getting up early all the time", he thought, "it makes you stupid. You've got to get enough sleep. Other travelling salesmen live a life of luxury. For instance, whenever I go back to the guest house during the morning to copy out the contract, these gentlemen are always still sitting there eating their breakfasts. I ought to just try that with my boss; I'd get kicked out on the spot. But who knows, maybe that would be the best thing for me. If I didn't have my parents to think about I'd have given in my notice a long time ago, I'd have gone up to the boss and told him just what I think, tell him everything I would, let him know just what I feel."
