The document discusses how to ask questions about someone's age in English using the verb "to be". It explains that in English, we use "to be" followed by their age in years to ask "How old are you/he/she/they?". For example, "How old is Jack Nicholson? He is 74 years old." It also notes that in Spanish, we use the verb "tener" (to have) instead of "ser" (to be) when giving someone's age, as in "Jack Nicholson tiene 74 años". The document provides examples of asking the ages of individuals and couples, and emphasizes only using the verb "to be" followed by years old in English.
