Final answer:
The words "regret" and "removal" convey a sense of sorrow and loss, creating a regretful tone in the text. These terms are linked with negative feelings and reflection on undesirable outcomes or the absence of something, which does not align with joyfulness, neutrality, or hopefulness.
Step-by-step explanation:
The tone a writer uses is critical in conveying the emotion and mood of the text to the reader. In the context of words such as "regret" and "removal", these terms typically signify a sense of loss or sorrow.
The word "regret" inherently carries a sense of sadness and reflection on past actions or events that one wishes could have been different, or decisions that lead to negative outcomes. The term "removal" suggests that something has been taken away, which can often lead to a feeling of emptiness or loss. Given these connotations, it is clear that the tone created by using these words is not joyful, neutral, or hopeful.
