I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In June 1990, The Times ceased its policy of using courtesy titles ("Mr", "Mrs", or "Miss" prefixes) for living persons before full names on first reference, but it continues to use them before surnames on subsequent references. The more formal style is now confined to the "Court and Social" page, though "Ms" is now acceptable in that section, as well as before surnames in news sections."? 

Humans interact with others and cooperate in society, and are good examples of what kind of beings?
