The central idea of the selection is more likely to be "There are different ways to measure and express intelligence.”
This is because the selection talks about how intelligence can be measured in various ways, such as through IQ tests, emotional intelligence, and creativity. It also discusses how people can have different types of intelligence and how these different types can be valuable in different contexts.
"People who don’t know math well cannot appreciate math geniuses" is not mentioned in the selection and is not a central idea of the text.
