Q1. Correct answer is 3.
Reasoning:
1.The situation is not drastic enough for you to relegate an important
official task to secondary status, by giving precedence to a purely personal
matter. In any case, a friend who has so little consideration for you that
he imposes himself without warning, and insists that you neglect/ imperil
your job to boot, hardly merits this kind of response.
2.You need rest and sleep, and cannot do justice to both your job and to
your friend. You'll end up falling asleep at your desk or at the restaurant,
to your friend's indignation .
3.
He'll get the message that responsibilities cannot be
put on the back-burner for random, inconsequential personal affiliations
which, in any case, can be duly attended to, and compensated for adequately
later on without any personal animosities involved. It's just a matter of
taking a mature, professional, responsible and adult approach to the issue
4.Akin to (2)… Indecision has exacerbated matters. Even (1) is better than
this.
