I want to know the answer to the following question:
What historical mission is a major tourist attraction in San Diego?
All the background I'm provided with is that "Tourism is a major industry owing to the city's climate, its beaches, and numerous tourist attractions such as Balboa Park, Belmont amusement park, San Diego Zoo, San Diego Zoo Safari Park, and SeaWorld San Diego.". Is that enough to answer the question?
Answer: no
