To "inundate" means to flood, either literally with water or (more commonly) metaphorically with anything that happens to be "swamping" you. If you have a waterbed, you will be familiar with its "undulations" (movements in wavelike motions), which is a related word. You may have recognized the "in-" root, meaning "into," and chosen "enter." Though this is incorrect, don't beat yourself up over it—it's better to base a guess on one root than to guess randomly.

The prefix "en-" means put into or cause to be completely something, in this instance the word “engulf” means completely overcome or completely surround. It is usually heard in a sentence like “the log was engulfed in flames” meaning that it was overcome or surrounded by fire. So, "overcome" is the correct answer. None of the other answer choices are close in meaning to "engulf": ”embitter” means make someone bitter; “parody” means make fun of or imitate in order to make a joke about; “akin” means similar to; and “amiable” means sociable and friendly.

"Convene" means meet up or begin, so "meet" is the correct answer. To help you, "abolish" means get rid of, "suspend" means pause, "deny" means refuse, and "abject" means hopeless and miserable.

“Abdicate” means to give up the throne, to relinquish the throne. It can mean to relinquish any authority, but is most commonly linked to a King giving up power. The prefix ab- means to move away from, to give away, as seen in “abdicate” and “abstract,” which means away from the normal, not related to concrete objects. To provide further help, “abolish” means get rid of; “descend” means go down; “despair” means feel sad and hopeless, go down emotionally; an “atheist” is someone who does not believe in God.

The prefix ob- means in the way of, against. The word “obviate” means to make something unnecessary, to prevent something from happening. As such, it is closest in meaning to “preclude” which means to stop something from happening. To provide further help, “secede” means pull out of an union; “recede” means go back; “wanton” means random; “apparent” means obvious. 

"Decipher" means derive information from something that is encoded. Therefore, the synonym is "decode."

“Postpone” means to delay. The prefix post- ought to have been a clue here, because it means after. To provide further help, “commence” means begin; “pugnacious” means aggressive and determined; “aggravate” means make worse; “insinuate” means to imply an accusation, to suggest someone has done something wrong.

The suffix "-duce" means to lead to, to cause, so the word “induce” means to cause a reaction, to lead to action. It is most similar in definition to “stimulate,” which means to cause to happen, to inspire to action. To provide further help, “discern” means tell the difference, distinguish; “sanctify” means make holy; to “indulge” is to allow to have something pleasurable; “inculcate” means to instill, to teach through repetition.

"Disingenuous" is an adjective meaning "not truly honest or sincere" or "giving the false appearance of being honest or sincere," so we need to pick out an answer choice that is also an adjective and means something like "not honest." While "candid" may look like a potentially correct answer because it has to do with truth, "candid" actually means "truthful and straightforward; frank," so it is an antonym of "disingenuous" and cannot be the correct answer. "Deceitful," however, means "guilty of or involving deceit; deceiving or misleading others," so "deceitful" is the correct answer because it is the answer choice closest in meaning to "disingenuous."

"Disinterested" is an adjective that can mean either "not influenced by personal feelings, opinions, or concerns" or "having no desire to know about a particular thing : not interested." So, we need to pick out an answer choice that means something like "not influenced by emotions" or "not interested." "Partial," then, cannot be the correct answer because "partial" means " favoring one side in a dispute above the other; biased," making it an antonym of "disinterested." "Unbiased," however, is an adjective that means "showing no prejudice for or against something; impartial," and because it is the answer choice closest in meaning to "disinterested," "unbiased" is the correct answer.
