“Birthday” is defined as:

the day of a person’s birth; or
the anniversary of a person’s birth.

Ultimately, I guess it all depends on context. If an acquaintance made an inquiry regarding my birthday, I would give the month and date (i.e., the anniversary of my birth). If, however, a bouncer at a club so inquired, I would offer the month, day and year (i.e., the actual date of my birth). I agree that the context of the quiz was misleading.

In any case, I hope the quiz offered a fun little diversion. I personally like little brain teasers like that. My current problem, however, is that my wife answered every one correctly. I now want a new quiz and a rematch.

Just curious.

2. One. (Everyone has one birthday.)

3. All months have 28 days.

4. Six. (Three in the top of the inning and three in the bottom of the inning.)

5. No, a dead man cannot legally marry in California. (Still confused? Think about the definition of the word “widow”.)

6. Seventy. (30 divided by one half is sixty, and sixty plus ten is seventy.)

7. Two.

8. None. It was Noah’s ark, not Moses’ ark. (This is the one I missed.)

9. Twelve. (A dozen is twelve. Only a baker’s dozen in different — 13.)

10. Nine.

If you missed one or more, don’t feel bad. Many of the questions involve the kind of cultural bias that would prevent them from ever making it into a standardized test.
