2. Correct errors in the original: While it is important to ensure accuracy when summarizing, correcting errors in the original material is not the primary purpose of a summary. The focus is on capturing the essential points and main ideas, rather than addressing mistakes or inaccuracies.

3. Change technical terms to everyday language: While simplifying technical terms for better understanding may be employed in a summary, it is not the primary purpose of summarization. The main aim is to present the core concepts and essential information, regardless of whether technical terms are simplified or retained.

4. Include your opinion on the topic: Summaries are objective and should not include personal opinions. They aim to provide a factual and concise overview of the main points, without introducing personal biases or subjective viewpoints.

Therefore, after considering each option, it becomes evident that the correct purpose of a summary is to save the reader time by providing a condensed version of the original material.
