An effective way to organize note cards is a. alphabetically. b. a numbering system. c. by length of notes. d. by source.

Depending on what the note card entails, I would either do by A or D

I would do BOTH A AND D. if you organize it based on what it's about and in alphabetical order, then you know what you are looking for and what letter it is in.

When the author asks himself a series of questions, it conveys the way he thinks and where he stands.at least that's what i believe.
