Sherlock Holmes Info Page

From the website

http://www.crimelibrary.com/gangsters_outlaws/cops_others/sherlock_holmes/1.html

In a sea of fictional detectives that includes the greats, the near-greats, and a great many wannabes, the lighthouse that shines above them all is, of course, Sherlock Holmes. Created by Sir Arthur Conan Doyle and presented through the narration of the fictional Dr. Watson, Holmes is the most brilliant detective ever. His powers of observation seem supernatural until he utters the famous phrase,

“Elementary, my dear Watson,” and

proceeds to enumerate the logical

steps that have brought him to a

prescient conclusion. The most

innocuous detail can lead Holmes to

profound revelations.

There is another way to refer to the students who JUST watch MTV or JUST play video games. We use subtraction!

The blue area, MTV only students, is the same as M-G, because all of circle G, the green and yellow areas, gets subtracted out.

Same thing with the yellow area, video game only students.

It is the same as G-M.
