Which word means concerned with acquisition of knowledge?

• A. Abstruse
• B. Adjunct
• C. Cognitive
• D. Truculent

Answer: (C)

Think about terms that describe how we think, know, and learn. The word that fits best is one that directly relates to mental processes involved in gaining knowledge—thinking, understanding, and learning. That term is cognitive, which covers things like perception, memory, problem-solving, and how we acquire information.

Abstruse means something is difficult to understand, not about how we learn or think. Adjunct refers to something added on or an assistant, not a mental process. Truculent describes someone who is aggressively defiant or combative, again not related to knowledge or learning.

So the word that means concerned with acquisition of knowledge is cognitive. For example, cognitive skills are the abilities used to learn and process information.
