A "teacher" works inside a "classroom," similar to how a "scientist" works inside a "laboratory." A scientist may study "biology" or perform "experiments," but he does not work inside either of them. To further help you, a "lavatory" is a washroom or bathroom; a "labyrinth" is a complex maze.

"Drove" is the past tense expression of the verb "drive," so to solve this analogy, you have to find the past tense expression of the word "eat." “Ate” is the past tense expression of "eat," so "ate" is the correct answer.

The best answer is "museum is to painting," as a museum houses paintings for public viewing, much like how a library keeps books for public reading. Some of the other answer choices may be tempting, but are switched in structure, such as "money is to bank" instead of "bank is to money." "Zoo is to monkeys," may also be a tempting answer choice, but is too specific ("Zoo is to animal" would be a much better choice).

Milk is produced by cows at a dairy, but "dairy" could also refer to the group of food items to which milk belongs, as milk is a "dairy product." To figure out which of these analogies is at work, we should consider the answer choices through each lens to see in which way the correct answer relates to "bread." None of the answer choices describe a category to which bread belongs (like in the "milk is to dairy product" relationship), so we need to find an answer choice that describes the location at which bread is produced. Bread is produced at a bakery, just as milk is produced at a dairy, so "bakery" is the correct answer.

Since a bedroom is a room in which one sleeps, we need to pick out a word that describes an action that typically takes place in a kitchen. Of the possible answer choices that are verbs - "dance," "cook," and "snooze," "cook" makes the most sense. Since just as you sleep in a bedroom, you cook in a kitchen, "cook" is the correct answer.

To solve this analogy you first need to know that "emaciated" means starving, extremely skinny due to lack of food. So, if someone who is denied "food" becomes "emaciated" what does someone become who is denied "education?" The correct answer is "ignorant," which means lacking in knowledge, not understanding something.

To solve this analogy you first need to know that "anemic" means lacking color and energy. So, someone who is lacking "energy" is "anemic," what is someone who is lacking "hair" called? The correct answer is, of course, "bald."

The correct answer is "Houston is to city."

The first part of the analogy expresses that South America is a continent, and deals with geographical content. 

Houston is a city and also falls under the category of geography. 

"Metropolitan" means related to the city, urban. So, to solve this analogy you need to determine which of these words means related to the countryside, rural. The correct answer is "agrarian."

"Anorexia" is a medical condition that arises from a lack of food. So, to solve this analogy you need to determine what "insomnia" arises from a lack of. The correct answer is "sleep."
