In your example and in Spanish grammar is the “a ella” repetition of the indirect object “le” essential or is it an optional extention added for the sake of clarity?

The professor gives the certificate TO ME, looks like a indirect object pronoun ie me te le nos os les. Yet the lesson uses mi an adjectival pronoun??   In the test the answer requires Ella a subject pronoun as do some of the examples. 

The question does not enquire about the existence of a florist but the location. Therefore according to the lesson explanation the answer should be “Donde está”.  Please point me to the part of the lesson I have not understood.
