Answer:
in as few words as possible.
without using any notes.
without missing any details.
.
Step-by-step explanation:
I'm on the edge of "without missing any details" but I don't think you need to use this.
"In as few words as possible" would be true because if you use more than - at least - over eight or six sentences, you'd probably be revealing too many parts of what you are summarizing. The least sentences I would use would be three.
"Without using any notes" I mean you could use notes if your teacher allows you too, but usually you do use notes, or you just go off your mind because you've read the book or whatever you're summarizing, so you know what it's about.
I underlined the one that I was confident was the answer and italicized the ones I was on the brink of.
