Q. Consider the following statements:

1. Caffeine is present naturally in coffee, cacao, and tea.
2. By dry weight, tea leaves contain more caffeine than coffee beans.

Which of the above statements is/are correct?
Answer: Both 1 and 2
Notes: Caffeine occurs naturally in coffee beans, cacao beans, and tea leaves. Statement 1 is correct. Tea leaves have more caffeine than coffee beans by dry weight, but brewing typically extracts less, so a cup of tea generally has less caffeine than coffee. Statement 2 is also correct in the context of dry weight. Thus, both statements are correct.
