Last year I had the opportunity to encounter a set of five things. I learned that the names of these things are A, B, C, D, and E. In fact, these names were made verbally clear to me: “A as in Alpha, B as in Bravo, C as in Charlie, D as in David, and E as in Echo.” What are these things?
I read about these things in a Wikipedia article this week, which reminded me of my encounter from last year. Some of you might be familiar with these things. Others might need some more information than is offered in the previous paragraph. Feel free to ask yes-no questions, a la lateral thinking puzzles, in the comments.
