Extra credit on a test: Follow Up

The question I decided on is this: "Portland is the largest city in Maine. What is its population, to with 10,000 people?"

I'll post the answer when everyone has taken the test. Hint: it's pretty small for a state's largest city.

The test is over. The answer is about 64,000. I got answers ranging anywhere from 8,000 to 4 million (nearly four times the population of the entire state of Maine). It's kind of sad and amusing at the same time when you realize that so many kids have such little concept of anything like that.
