Why doesn't Omar know his exact age?

Why doesn't Omar know his exact age?

• A. Because he isn't sure when his birthday is.
• B. Because he never celebrates birthdays.
• C. Because his birthday is in a leap year.
• D. Because he forgot his birth date.

Answer: (A)

Knowing your exact age depends on knowing your birth date, because age is counted from that date each year. If Omar isn’t sure when his birthday is, he can’t reliably tell whether he has already had his birthday this year or if it’s still coming, which leaves his exact age uncertain by a year. The other ideas don’t directly explain the gap in knowledge: not celebrating birthdays doesn’t erase knowing the date, leap year is just a calendar quirk and doesn’t remove awareness of your birth date, and forgetting the birth date would also cause not knowing, but the clearest reason given is the uncertainty about the birthday itself.
