I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Within southern California are two major cities, Los Angeles and San Diego, as well as three of the country's largest metropolitan areas. With a population of 3,792,621, Los Angeles is the most populous city in California and the second most populous in the United States. To the south and with a population of 1,307,402 is San Diego, the second most populous city in the state and the eighth most populous in the nation."? 

What city with a population smaller than 10,000,000 is the northernmost mentioned in the passage?
