I believe “satisfyingly” would work, the definition of satisfyingly is: “in a way that gives fulfillment or the pleasure associated with this.” The definition of “proudly” is: “with a feeling of deep pleasure or satisfaction in one's own achievements, qualities, or possessions or those of someone with whom one is closely associated.” The word satisfy is used in the definition so I believe they are similar!
Answer:
D. It is a fragment and needs a subject.
Explanation:
"Flew through the meadow" describes something that an object does. It doesn't specify a subject and it doesn't make much sense without one. A good example of a subject for this sentence fragment would be "The bird" or "The butterfly", which would make the sentence "The bird/butterfly flew through the meadow." That would be a complete, logical sentence, since an object to perform the given action is present.
