Which term describes accumulated knowledge?

• A. Fluid intelligence
• B. Whole-brain death
• C. Brain death
• D. Crystallized intelligence

Answer: (D)

Crystallized intelligence describes accumulated knowledge and skills gained through education and life experiences. It includes things like vocabulary, general information, and cultural know-how. This type of intelligence builds up over time and tends to stay strong or even improve with age, unlike fluid intelligence, which is the ability to reason and solve new problems without relying on what you already know. The other terms aren’t about knowledge—they either describe problem-solving with novel information (fluid intelligence) or refer to irreversible loss of brain function (brain death, whole-brain death). So the term for accumulated knowledge is crystallized intelligence.
