B. the history of California
For a speech, 10 minutes is really just enough time to pretty much cover the basics. When we consider that the average time it takes to read/speak is approximately 250 words a minute, and with the understanding that one typed page is 250 words, this means that 10 minutes would cover only four pages of text. With that in mind, the topic of “The History of California,” it can be safely assumed that only a superficial covering of the history would be covered because there is so much that could be covered, especially keeping in mind that California’s history could include everything from prehistoric times (or earlier) to the present day. When deciding on a topic, one should always keep the required length in mind and decide whether the topic is suitable for the page/time length because for broad topics many pages and lots of time would be required in order to adequately cover everything of which it is comprised. For low page/time requirements, a narrow topic is what would be needed.
D. "this was an uneasy secret..."
