Translation:You will think about this exercise for Thursday.
What does it mean? To what does "jeudi" relate? To exercise? Then is it an exercise that must be finished before Thursday, or that must be performed on Thursday being previously thought out for several days? Or should I think about the already totally failed exercise till Thursday when it'll be discussed? Or finally is this Translation an exercise to translate a highly ambiguous French phrase into equally ambiguous English one, thus achieving a perfect match in their outstanding ambiguity?
