Answer:
Without a specific reference to the essay by Jhumpa Lahiri in question, it is challenging to give a precise answer. However, I can provide some general insights.
An author may choose to end an essay with a quotation for various reasons:
1. It might be used to encapsulate the theme or message of the essay, bringing the reader back to the central idea.
2. A quotation can lend an external authority to the author's argument, making it more convincing.
3. Quotations can stimulate thought and leave a lasting impression, effectively making the conclusion more memorable.
Whether or not this is an effective strategy largely depends on the content of the essay, the quotation chosen, and how well it ties into the overall argument or theme of the essay.
As for alternative strategies, there are several:
1. Summarizing the main points: This helps to consolidate the argument and make it easier for the reader to remember.
2. Presenting a call to action: If the essay is persuasive in nature, the author might want to encourage readers to take some action in response to the argument presented.
3. Ending with a question: This could stimulate thought and encourage further exploration of the topic.
4. Providing a future prediction or implication: This helps the reader understand the potential impact or importance of the essay's argument.
Each of these strategies could be effective depending on the context, goals, and style of the essay.
