A "neophyte" is someone who is a beginner or a novice, so "novice" is the correct answer.

For further help, "intermediate" means middle or of a difficulty between easy and challenging. Finally, "cathartic" means healing due to allowing one to purge one's negative emotions.

"Credible" means believable or trustworthy. For example, a newspaper is credible if it has high reporting standards and rarely makes mistakes or reports inaccurate information. So, "trustworthy" is the correct answer.

If you connected the adjective, "pacific," with the Pacific Ocean, you made a proper connection, though it probably didn't help you with the definition, as all of the options could describe that body of water.

The Latin root "carn" means meat or body, so a “carnivore” is a meat-eater. A “herbivore” is an animal that eats plants (the root "herb" meaning plants); a “vegetarian” is a human that does not eat meat; and an “omnivore” is an animal that eats both plants and meats, the prefix "omni-" meaning all. "Voracious" means extremely hungry or fervent.

The Latin root "jud" means law, so “judgment” is a ruling by a court of law. It can also refer to the ability to make good decisions or having good sense. “Nonsense” means speech or writing that makes no sense; “wit” is the ability to be funny by being clever; “resolve” is determination; and "honesty" is truthfulness.

The Latin root "fid" means faith or trust, and the Latin prefix "con-" means with, so it makes sense that to “confide” means to put trust in and to tell secrets to someone. The Latin prefix "mis-" means not, so it makes sense that “mistrust” means to suspect and not trust and that “misunderstand” means to not understand, or to understand incorrectly. “Reprimand” means to punish for a relatively small wrongdoing.

The root "scribe" means write, and the prefix "pre-" means before, so it makes sense that “prescribe” means recommend the use of (often specifically in the sense of a doctor recommending and authorizing that medicine be given to a patient), since when a doctor prescribes a patient a medication, he writes down a prescription; this means that "recommend" is the answer choice closest in meaning to "prescribe."
