The prefix "super-" usually means better or best but can also mean over or on top, so the word “superimpose” means to put something on top of something else. The closest answer choice to this is “overlay.” To provide further help, “interject” means interrupt; “mitigate” means lessen, alleviate; “declare” means announce, say formally; “promote” means support.

The prefix per- means through, so the word “pervade” means to spread, or to have spread, throughout something. To provide further help, “undermine” means weaken. 

In this question, the answer that makes the most sense is strengthen or support.  When you reinforce, you strengthen something.

To "expedite" literally means "to free the foot;" (you may recognize the "ped" root from words such as "pedicure"). It derives from the same roots as the noun, "expedition," though it has a different meaning. Given the etymology of "expedite," you might (logically) think that it means "to flee." A red flag arises, however, when you see the other option of "evacuate," which has a very similar sense to "flee." Sometimes you can use an observation like this to eliminate possibilities: two near-synonyms among your answer choices likely means that both are wrong. The true sense of the English word "expedite" is to make easier or facilitate: your "foot" is "freed" (metaphorically) from imPEDiments.

The root "cis" means related to cutting and the prefix "ex-" means related to leaving or being sent away. So “excise” literally means to cut away, but also means “remove.” To provide further help, “prepare” means get ready; “create” means make; “edify” means build; “invoke” means call upon. 

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.
