Final answer:
The best description of Robert J. Sternberg's triarchic theory of intelligence is that intelligence consists of three related components: analytical, creative, and practical intelligence. These three components show how Sternberg's theory views intelligence as more complex than a single ability or something solely influenced by genetics or environment.
Step-by-step explanation:
The triarchic theory of intelligence, proposed by Robert J. Sternberg in 1986, describes intelligence as composed of three interconnected components: analytical intelligence, creative intelligence, and practical intelligence. Analytical intelligence involves the ability to process and analyze information, creative intelligence is associated with the capacity to deal with novel situations and devise innovative solutions, and practical intelligence refers to the ability to adapt to, shape, or select environments to meet both personal goals and the demands of one's everyday world. These facets represent a broader vision of intelligence beyond traditional academic skills.
Regarding the student's question, the answer that best describes Sternberg's triarchic theory of intelligence is that intelligence involves three distinct but related components: analytical, creative, and practical intelligence. This reflects the multifaceted nature of intelligence as opposed to a singular general ability, or a factor primarily determined by genetics or environment alone.
