The suffixes "_-_able" and "-ible" generally mean able to be or able to do, as in the the word “manageable,” which means able to be managed. To solve this analogy, you need to determine which of these answer choices means able to be defended. The correct answer is “defensible."

The suffix ­_-ible_ means able to be, so the word “edible” means able to be eaten, and the word “tangible” means able to be touched. The prefix tan- generally suggests things touching or being able to touch. To provide further help, “audible” means able to be heard; “visible” means able to be seen.

"Tasty" food is food that is enjoyable to taste, so you need to pick out an answer choice that describes something that can be "melodious." A "melodious" sound is a sound that is pleasant to listen to, so "sound" is the correct answer, because just as food can be "tasty," sound can be "melodious."

A “wizard” is a male witch. To provide further help, “witchcraft” is the practice of magic by witches. The suffix "-craft" suggests a type of work or craft. A “humanist” is someone who has great faith in the capabilities of mankind and who thinks rationally about the world.

The suffix "-ten" means to make, so “lengthen” means to make longer and “moisten” means to make wetter.

A “magician” is someone who practices magic, so to solve this analogy, you have to find the word that means someone who studies history, or “historian.” “Magician” and “historian” both have the suffix "-ian," which means type of person. To provide further help, “historiography” is the study of historical practice; a “scientist” is someone who studies science; “humanities” is a broad subject group including history, art, and literature; a “warlock” is a male witch, a wizard.

The suffix "_-_ward" means having to do with the direction of \[adjective or preposition\]. Moving "forward" is the opposite of moving "backward," so you need to pick out an answer choice which represents the opposite of "up." "Down" is the opposite of "up," so "down" is the correct answer.

The suffix "-meter" suggests that the word in question will relate to the measurement of something. The prefix "therm-" or "thermo-" means having to do with heat, temperature, or fire, so a “thermometer” is something used to measure temperature. So, to solve this analogy, you need to pick out an answer choice that describes what a ruler measures. A ruler measures length, so "length" is the correct answer.

"Get" and "obtain" are synonyms because they mean the same thing, so to solve the analogy, you need to pick out the answer choice which is a synonym of "deceive."
