You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.

How are i.e. and e.g. pronounced?
Solution: i.e. stands for id est (Latin), which means 'that is'. You use it to link in a deeper explanation about something. Pronounce it 'eye - ee'. e.g. stands for exempli gratia (also Latin), which means 'for example'. You use it to link in an example of a more generic term. Pronounce it 'ee - jee'
Why? Perfect answer because it's consistent with context uses required information from the question to provide the detailed answer with an example.

New input: When should whilst be used instead of while? For example, should I use the first or the second sentence? They don't do this whilst they do that. They don't do this while they do that. Which would be correct?.
Solution:
I believe while and whilst are interchangeable, but whilst is more archaic and adds a nice flavoring to the sentence. That being said, 'whilst' doesn't seem to come up so often in the middle of a sentence as you had it there, so I would use 'while' in that case, even though both are grammatically correct. Whilst seems more apt to be put at the beginnings of sentences, e.g. Whilst going about my merry way I chanced upon a vagabond. Taking this serendipitous opportunity to satiate my bloodlust I decapitated him with a fork.
