The prefix "pre-" means coming before, so it makes sense that "prescience" means knowledge about what is coming in the future, or “foresight." As for the other answer choices, “ignorance” means cluelessness or lack of understanding; “nostalgia” is a feeling of fondness about the past; “prowess” means skill; and “account” means story, version of a story told by a specific person, ledger of money withdrawn and deposited at a bank, or password-protected personal identity on a website.

The prefix "in-" means not, and "credible" includes the root "cred-," suggesting it has something to do with belief like other words that contain this root, like "incredulous" (surprised at something that seems unbelievable). "Credible" by itself means believable or trustworthy, so it makes sense that "incredible" means not able to be believed or surprising. This means that "unbelievable" is the correct answer. As for the other answer choices, "untouchable" means unable to be touched; “edible” means able to be eaten; "pardonable" means able to be pardoned or excused; and "workable" means potentially successful or able to be worked with.

The prefix "im-" means stop or not, and "mobilize" means make able to move or prepare and deploy military troops and units, so it makes sense that "immobilize" means make unable to move or continue. As for the other answer choices, "dissolve" means melt away or, more precisely, put a solid into a liquid solution such that it breaks apart at the molecular level and is no longer visible to the naked eye; “form," when used as a verb, means shape or make; and “function,” when used as a verb, means work.

The prefix "eu-" means good, so it makes sense that "euphoria" is a feeling of great happiness; this means that "elation" is the correct answer, as "elation" also means great happiness. A “district” is a distinct area in a larger area, often in a city; “despair” is hopelessness; “desolation" means despondency, loneliness, or emptiness; and “judgement” means an official decision about a disputed issue, often from an authority figure.

The prefix "ex-" means outside or beyond, and the "-cede" portion of "exceed" derives from a Latin word that means go, so it makes sense that "exceed" means go beyond or do more than you need to. “Surround” means cover or be all around something; “defend” means look after or protect; and “announce” means declare information publicly for the first time.

The prefix "re-" can mean back or again, and the "-vert" part of "revert" stems from a Latin root that means turn and is found in other English words like "invert," "convert," "divert," and "versus." So, it makes sense that "revert" means go back or return to something one did previously or a state one was in previously. As for the other answer choices, “respond” means answer back; "reconsider" means think about once again or go back on one's initial decision in favor of an option one didn't initially choose; “deplete” means reduce or minimize; and “depose” means get rid of a person in power against that person's will.

The word replicate has the prefix "re-," which is very useful for figuring out its meaning. This prefix often means again, as we use it in "repeat" and "recede." The portion "-plicate" actually means to fold. Thus, a replication is like a "re-folding" or a "folding back on oneself." Thus, a "replication" is a copy or a clone of something else.

The prefix "inter-" should help you to figure out this word's meaning, even if you do not know it otherwise. This prefix means between. When you go to a theatre show, there is "intermission." This is the break that is between the main acts. This prefix should not be confused with "intra-," which means within. Now, "interspersed" means scattered between. When something is sparse, it is scattered. Thus, the "-spersed" portion of the word means scattered. When you intersperse something among other things, you mix it into them. Thus, the best option for this question is "mix."

"Immoral" is made up of a root word, "moral," and a Latin prefix, "im." "Moral" means to act correctly based on concepts of right and wrong. The prefix "im" means not. Therefore, immoral means to act incorrectly. An example would be that it is immoral to steal.

The root word, "yield" means to surrender or give way. For instance, a yield sign on a road means that you must allow cars on the other road to have the right of way. The Latin prefix "un" means not. Therefore, "unyielding" means to NOT surrender. The answer, "inflexible" has another Latin prefix, "in," which means not. "Inflexible" means to NOT be flexible or to NOT give way.
