Answer:
to share insights about personal experiences
Explanation:
Reflection means to think about something that happened in the past, so we can immediately eliminate answer choices 2 and 3. Comparing the past and the present is just seeing how they are different, and reflections are often personal, so I would go with the first answer choice.
Some domains such as .com, .org, and .net can be purchased and used by any individual. However, the domain .edu is reserved for colleges and universities, while .gov denotes a government website. These two are usually credible sources for information (though occasionally a university will assign a .edu address to each of its students for personal use, in which case use caution when citing). Be careful with the domain .org, because .org is usually used by non-profit organizations which may have an agenda different than educating.
