You are emailing three colleagues to ask them to review a document before a Thursday deadline. Where should the request and the deadline appear?
توضیح
Recipients decide whether and when to deal with a message from its opening, and many will not read a long message to the end on first pass. Putting the ask and the date where that decision is made ensures the action is registered even by someone skimming; the background remains available for those who need it. Options 2 and 3 place the only time-critical element where it is least likely to be seen. Repetition (option 4) adds length and obscures which statement of the deadline is authoritative.
