Most people have an intuitive【C1】______of what intelligence is, and many words in the Engl

ish language distinguish【C2】______different levels of intellectual skill: bright, dull, smart, stupid, clever, slow, and so on. Yet no【C3】______accepted definition of intelligence【C4】______, and people continue to debate【C5】______, exactly, it is.【C6】______scientists are asked to define intelligence【C7】______what causes it or what it actually is, almost every scientist【C8】______a different definition. For example, in 1921 an academic journal asked 14【C9】______psychologists and educators to define intelligence. The journal received 14 different definitions. People in the general population have【C10】______different conceptions of intelligence than do most experts. Now some scholars argue that this definition is【C11】______and that intelligence is whatever abilities are【C12】______by one's culture.【C13】______to this perspective, conceptions of intelligence【C14】______from culture to culture. For example, North Americans often associate verbal and【C15】______skills with intelligence, but some【C16】______cultures in the islands of the South Pacific view【C17】______memory and navigational skills as【C18】______of intelligence. Those who believe intelligence is culturally【C19】______dispute the idea that any one test could fairly measure intelligence【C20】______different cultures.
