- Refer to the Venn diagram. Which animal should be written in the overlapping region of "Farm Animals" and "Can Fly"?
Answer: duck
A duck lives on farms and is able to fly, so it belongs in the intersection. A cow and goat are farm animals that cannot fly, while an eagle can fly but is not typically a farm animal.
- Refer to the stacked bar chart. Which weather word belongs in the segment representing 'precipitation'?
Answer: rain
Rain is a form of precipitation. Fog, wind, and sun are other weather phenomena but not classified as precipitation.
- Look at the diagram. Which food belongs in the intersecting area of both circles?
Answer: cheddar
Cheddar cheese is both dairy and protein, so it belongs in the overlapping area. Salmon is protein but not dairy, broccoli is a vegetable, and apple is a fruit.
- If you were classifying words by their relationship to time and permanence, which word would be grouped differently from the others?
Answer: Eternal
Temporary, brief, and momentary all describe things that last for a short or limited time. Eternal describes something that lasts forever, without beginning or end, making it the opposite concept and therefore belonging to a different category based on duration and permanence.
- When classifying by the type of skill or ability required, which activity requires fundamentally different capabilities than the others?
Answer: Solving a mathematics problem
Composing a symphony, writing a novel, and creating a sculpture all require primarily creative, artistic abilities and imagination. Solving a mathematics problem requires primarily logical, analytical thinking and systematic reasoning, making it fundamentally different from the creative arts in terms of the type of mental processes involved.
- When considering the method of movement or locomotion, which word represents a fundamentally different category from the others?
Answer: Swimming
This question tests your ability to categorize different types of movement by identifying which one requires a fundamentally different environment or mechanism.
When you examine each movement type, three of them share a crucial characteristic: they all occur on solid surfaces using body contact with the ground. Slithering (A) describes how snakes move by pushing their bodies against the ground in wave-like motions. Crawling (C) involves moving on hands and knees or belly along a surface. Creeping (D) refers to slow, careful movement along the ground, often staying low to avoid detection.
Swimming (B) is fundamentally different because it requires a liquid environment rather than a solid surface. While the other three movements involve friction and contact with the ground, swimming involves displacing water and using buoyancy. The mechanics, environment, and physical principles are completely distinct from ground-based locomotion.
Looking at why the wrong answers don't work: Choice A (slithering) is surface-based movement like crawling and creeping. Choice C (crawling) shares the same ground-contact principle as slithering and creeping. Choice D (creeping) also involves moving along solid surfaces using the same basic mechanical principles as the others.
For CogAT classification questions, look for the item that operates under different rules, environments, or mechanisms rather than just superficial differences. The key is identifying which choice requires a fundamentally different set of conditions or principles to function, not just variations of the same basic concept.
- Refer to the pie chart below. Which month should go into the smallest slice labeled "Winter Month"?
Answer: December
December occurs in winter. The other months are summer (July), spring (April), and autumn (October).
- Which word belongs in a different category when considering the level of certainty or definiteness each word expresses?
Answer: Probably
Absolutely, definitely, and certainly all express complete certainty or 100% confidence. Probably indicates likelihood but not complete certainty, expressing only a high degree of possibility rather than absolute conviction, placing it in a different category of certainty level.
- Use the bar graph below. Which sport fits the empty bar labeled "Indoor Team Sport"?
Answer: basketball
Basketball is a team sport played indoors. Surfing and skiing are outdoor individual sports, archery is usually individual.
- Look at the bar graph. Which book type belongs in the empty Fiction category?
Answer: fantasy novel
Fantasy novels belong in the fiction category. Biography, poetry, and atlas are non-fiction or separate literary categories.
- Which word belongs in a different category when considering the source or origin of the attribute being described?
Answer: Learned
This question tests your ability to categorize words based on their underlying meaning and origin. When you see questions asking about grouping words by category, look for the common thread that connects most options, then identify the outlier.
Three of these words—genetic (B), inherited (C), and hereditary (D)—all describe traits or characteristics that are passed down naturally from parents to offspring through biological processes. These terms relate to what you're born with: your eye color is genetic, height tendencies are inherited, and certain diseases can be hereditary. They all share the same source or origin: biological transmission from one generation to the next.
However, "learned" (A) describes something completely different in terms of origin. Learned behaviors, skills, or knowledge come from experience, education, practice, or environmental exposure after birth. When you learn to ride a bike, speak a language, or solve math problems, these abilities aren't passed down through genes—they're acquired through your interactions with the world around you.
Choice B (genetic) is wrong because it refers to traits determined by genes passed from parents. Choice C (inherited) is wrong because it describes characteristics received from ancestors through biological inheritance. Choice D (hereditary) is wrong because it means traits that run in families due to genetic factors.
Remember this pattern: when categorizing words on the CogAT, look for the fundamental difference in meaning or origin. Often, three choices will share a common source while one stands apart with a completely different underlying concept.
