A crocodile is a kind of reptile, so we need to pick out an answer choice that describes a category that a penguin would fall into. While “bird” and “bird of prey” might each look like a potentially correct answer, “bird of prey” specifically means “a predatory bird; a raptor,” and because a penguin does not fall into this specific category of birds, but is still a bird, “bird” is the correct answer.

Since a brontosaurus is a kind of dinosaur, we need to pick out an answer choice which is a kind of cat. Of the answer choices that are nouns ("leopard," "tyrannosaurus," and "zoo"), only two are animals ("leopard" and "tyrannosaurus") and only "leopard" is a kind of cat. Because a leopard is a type of cat, just like a brontosaurus is a type of dinosaur, "leopard" is the correct answer.

Since a daisy is a kind of flower, we are looking for an answer in which the first word is a type of the second word. Thus, the best answer choice is "lollipop is to candy" because lollipops are a type of candy!

Since a daisy is a type of flower, we're looking for another pair of words in which the first word is a type or kind of the second word. While "oak is to tree" and "pinecone is to tree" may both look like correct answers, "pinecone is to tree" can't be the right answer because while a pinecone is a part of a tree, it is not a type or kind of tree. "Oak is to tree," on the other hand, is the correct answer because just like a daisy is a kind of flower, an oak is a kind of tree.

In this analogy, tea is an example of a beverage, so we need to pick out the answer choice in which the first word is an example of the second. The only answer choice that fits this description is "library is to building," since a library is a type of building just like tea is a type of beverage.

A “shark” is a “predator,” a “predator” is an animal that hunts other animals. So to solve this analogy you have to determine which of these groups a “mouse” fits into. The correct answer is “prey,” which means an animal that is hunted by other animals.

"Lunch" is a specific kind of "meal," so this analogy relates a general term to a category into which that term falls. "Cook is to food," "drink is to thirsty," and "race is to run" do not meet this criteria. "Kitchen is to house" may look like it is similar to "lunch is to meal," but a "kitchen" is a part of a house, not a specific kind of house, so "kitchen is to house" cannot be the correct answer. Lunch is a specific kind of meal just as baseball is a specific kind of sport. Therefore, "baseball is to sport" is the correct answer.

The first phrase in this analogy relates a skill set to an occupation to whom such a skill set would be useful. "Corruption is to judge" is incorrect because we would not want a judge to be corrupt. "Microscope is to farmer" and "strength is to dentist" do not relate useful traits to their given occupations, and '"education is to machine" does not make sense either. Generally, speed is useful to an athlete just as wit is useful to a comedian. Therefore, "wit is to comedian" is correct.

Since a zebra is a type of animal, we are looking for an answer in which the first word is a type of the second word. The best answer is "rose is to flower" because a rose is a type of flower.

Red is an example of a color, so, to solve this analogy, you have to determine which of the answer choices is a category in which "eighteen" can be placed. The correct answer is therefore "number," because "eighteen" is a number.
