Answer:
The lines are ambiguous because they have more than one possible meaning.
Step-by-step explanation:
Ambiguity is the duplicity of meanings in the same sentence.
Because it brings together more than one possible interpretation, ambiguities can lead to disagreement in discourse, which is why they should be avoided in formal discourses. However, this is a feature widely used in poetic texts, as it offers greater expressiveness to the text. Based on this, we can conclude that the lines of Emily Dickinson's poem are ambiguous because they have more than one possible meaning.
