The purpose of a "furnace" is to provide "heat." So, to solve this analogy you need to determine what the purpose of a "generator" is. Well, a "generator" generates "electricity," so this is the correct answer.

A "legislator" is someone who works in government and makes "laws." So, to solve this analogy you need to determine which of these is an item made by a "cobbler." The correct answer is that "cobblers" make "shoes."

A "crater" is a hole in the ground formed by the impact of a meteor with the surface of a planet. A "crater" is therefore formed by a "collision." So, to solve this analogy you need to determine which of these is formed by "erosion." Well, "erosion" is the process of wearing something down through constant exposure to wind and water. "Cliffs" are formed by "erosion."

A "microscope" is a piece of machinery used to look at the small world, so to solve this analogy you have to identify the name of the machine used to look at the much larger world. The correct answer is “telescope.” The prefix, micro­-, means small, and the prefix, macro­-, means big; however in this instance you use the prefix, tele-, which means at a distance or far away. For clarification, "garrulous" means talkative.

A bed is an object which is used to fulfill the action of resting. So, to solve this analogy you have to identify which of these answer choices is an action intended to be undertaken in a car. The correct answer is “travel.” For clarification, "automobile" means car, and "supplant" means to replace.

One might use a shovel to dig something, and "dug" is the past tense of "dig," so we need to pick out a word that both a.) is a verb describing what someone might do with a paintbrush and b.) is in the past tense. While "paint," "painter," "painted" and "painting" may all seem like potentially correct answers, "paint" is either a noun or a present-tense verb, "painter" a noun meaning a person who paints, and "painting" a present progressive verb, so the only answer choice that fulfills both our requirements is "painted."

A tablecloth covers a table, so we need to pick out an answer choice that describes something that covers and protects a person. While “quilt” and “sail” might each look like a potentially correct answer, because each refers to a piece of cloth, a “sail” is specifically the piece of cloth that catches the wind on a sailboat and propels it and does not necessarily cover and protect a person. A “quilt,” however, is defined as a large sewn covering used on beds made up of many small pieces of cloth joined together over a layer of padding and a back layer of cloth. Just as a tablecloth covers a table, a quilt is made to cover a person, so “quilt” is the correct answer.

A phone allows one to communicate, so to solve this analogy, you have to determine what it is that a car allows one to do. The correct answer is "travel." 

We use "toothbrushes" in our "mouths." We use "combs" in our "hair." The relationship is tool to body part. None of the other analogies have this relationship.

Bats are used in baseball, but humans do not have baseballs as parts of their body. Chain-link fence is composed of wire, but neither word is related to a body part. Writers use pens but writers are not a body part. Feather is a body part of a bird, but bird is not a part of the human body.

A sword is the weapon used in fencing, while a lance is the weapon used in the medieval sport of jousting. This analogy relates an implement to the fighting sport for which it is used. The rest of the options are, indeed, sports, but they are sports that do not require a lance.
