Final answer:
The introduction presents the topic and thesis, sparking interest in the reader, while the conclusion provides a summary and reiterates the main argument and thesis, often suggesting further research or broader implications.
Step-by-step explanation:
The introduction acquaints the reader with the topic, while the conclusion summarizes or supports the paper's main idea. In the introduction, the issue or main idea of the research is presented, its importance is established, and the author's thesis is posed. This section is crucial as it sparks interest and leads to a clear thesis statement.
The conclusion, on the other hand, often revisits the main points of the paper, providing a summary of the arguments and a restatement or reinforcement of the thesis. It discusses the results in the context of the bigger picture and may propose future research needs or highlight unanswered questions.
The conclusion may also show the implications of the claims or the connections between the literature and real life, leaving a lasting impression on the reader.
