The suffix "-able" means able to be,so “fathomable” means able to be fathomed—that is, able to be understood. Notice how all of the answer choices use "-able" or ­"-ible"; this means that you will have to try and figure out which answer choice's stem is most similar to “fathom.” The correct answer is "comprehensible" because "comprehend" means understand. As for the other answer choices, “amiable” means friendly or sociable; “agreeable” means pleasant or easy-going; “intangible” means not able to be touched or not able to be defined, and "comfortable" means cozy and pleasant.

"Reprehensible" means disgraceful or shameful, so "shameful" is the correct answer. None of the other answer choices are close in meaning to "shameful": “optical” means related to seeing; “auditory” means related to hearing; "triumphant" means victorious; and "bewildered" means very confused.

The suffix -cide means related to killing, and the prefix homi- means related to humans, or to sameness (depending on context).

Both words share a link with the root “fan,” as in football fan. “Fanaticism” can also be called “zeal,” which is a strong feeling of interest and enthusiasm that makes someone very eager or determined to do something. If you show “zealous” behaviour then you are full of “zealotry.” To help you “idealism” is the attitude of a person who believes that it is possible to live according to very high standards of behavior and honesty. “Jive” means a type of fast lively dance or music that was especially popular in the early part of the twentieth century; it can also mean informal language that includes many slang terms.
