Answer:
The biggest problem with this paragraph is the "Wildflowers in high meadows. Butterflies hovering" fragments.
Explanation:
A fragment is a group of words that is similar to a sentence in the sense that it starts with a capital letter and ends with punctuation (like a period) but that it is not a sentence as it does not convey a complete idea, thus, they are usually wrong.
The fragments "Wildflowers in high meadows." and "Butterflies hovering." are the two errors in the paragraph, and we can correct them by either adding a main clause that completes the idea or adding this fragments to an already-existing main clause.
For example, a way we can fix them are "We would enjoy the view of wildflowers in high meadows and butterflies hovering".
