Answer:
9
Step-by-step explanation:
The world has proven that every year, 30% of people with IQ scores below average still achieve outstanding success.
In response to the question of how IQ is determined to succeed, after years of research, in 1988, Professor Howard Gardner and his team put forward the theory of "multi-intelligence".
According to this theory, intelligence is initially divided into 7 categories, known as 7 thinking powers.
By 1999, Howard Gardner divided intelligence into 9 thinking powers, whereby every ordinary person was to some degree intelligent at one or more of these 9 thinking powers.
