One way "intelligence" can be interpreted is as "general problem$-$solving ability." Explain why it is not valid to measure intelligence by a test that asks questions such as

Who wrote "The Star$-$Spangled Banner?"

Who won the last soccer World Cup?

These questions are a valid way to measure intelligence because knowledge of facts is an important part of being intelligent.

These questions measure knowledge of facts rather than general problem$-$solving ability.

These questions could be used to measure intelligence in countries other than the United States, where people are not as familiar with the Star$-$Spangled Banner.

There are too many different forms of intelligence for it to be measured in any meaningful way.
