It seems to me that, at least at the A1/present tense level here, this exercise might best be reworded to say "Cécile takes their order" - this is in the present. I am not sure there is any benefit in this exercise to using "goes and takes".
Using "Cécile goes and takes", while present tense, is really one action (taking the order), however the "goes" and that the acceptable answer uses "va prendre", to me anyway, implies near future tense, which is beyond the scope of this exercise it seems.
If the intent is to use near future, then use "Cécile will go and take their order", but that does not make sense for this exercise.
Based on other comments, it seems others have similar issues.
Similarly, on the last sentence, the answer seems to match the actual text, using "faire" instead of the text in the hint, which would imply using "prendre". I might recommend just deleting the hint.
