When a person uses information that she or he has been taught to solve problems in a rational way, Robert Sternberg's triarchic theory of intelligence would suggest that person was demonstrating what kind of intelligence? experiential intelligence componential intelligence practical intelligence contextual intelligence

The correct answer is:

**componential intelligence**

### Explanation:
Robert Sternberg's triarchic theory of intelligence identifies three types of intelligence:

1. **Componential Intelligence (Analytical Intelligence):**
- This refers to the ability to analyze, evaluate, and solve problems using logical reasoning and critical thinking.
- It involves skills like comparing, contrasting, evaluating, and applying knowledge that has been taught.
- In this case, the person is using information they have learned to solve problems in a rational way, which aligns with componential intelligence.

2. **Experiential Intelligence (Creative Intelligence):**
- This involves the ability to deal with novel situations and generate new ideas or solutions.
- It focuses on creativity and innovation rather than applying pre-learned knowledge.

3. **Practical Intelligence (Contextual Intelligence):**
- This refers to the ability to adapt to, shape, or select environments to meet one's goals.
- It is often referred to as "street smarts" or common sense.

4. **Contextual Intelligence:**
- This term is sometimes used interchangeably with practical intelligence, as it relates to understanding and navigating real-world contexts effectively.

Since the question specifies solving problems in a rational way using learned information, **componential intelligence** is the best fit.
