Depends on the plot but the last one
The correct answer to this open question is the following.
The last time I used a text reference successfully to preview, prepare for, review, or locate the information I was learning was precisely last week.
I was trying to learn more about the Revolutionary War of Independence, trying to collect some valid information to write an essay. So I had to search on the internet because the school library and the local library are closed. So I search on the internet to look for some secondary sources that could help me do my work.
To do so, I had to use a text reference to search for the proper information and be more specific. Doing this I found very good information about the reasons the American colonists had to start the Revolutionary War against the British troops. I even found something that caught my attention: Thomas Pain's "Common Sense." A pamphlet which ideas served as inspiration for the American colonists.
