The "ed-" in "educate" stems from the "ex-" prefix, here meaning out of; the "-ducate" portion of the word stems from Latin roots meaning lead. So, to "educate" stems from roots that mean lead out of or train. "Educate" has since shifted its definition and now means instruct as a student or "teach." As for the other answer choices, “demand” means forcefully ask for or say something has to be done or given; “elude” means get away from or hide from; “irritate” means annoy or vex; and "learn" means gain knowledge about a specific concept or procedure.

"Imply" means suggest something without stating it explicitly, so "suggest" is the correct answer. "Describe" means provide details regarding a person or some event. "Classify" means arrange in groups according to the qualities of the thing being sorted. "Contribute" means fund or to give money to some cause. "Earn" can mean either deserve when referring to something like respect, or get in return for work when referring to money.

"Baffle" means confuse, so "confuse" is the correct answer.

First of all, do not confuse the word "commend" with "comment." The latter ("comment") might be used to mean remark when used as a noun, as when we "make a comment"; it can also be used as a verb meaning say, as in "to comment on something." The word we are looking for is a synonym of "commend." When we "re-commend" someone, we tell judge that someone is good at something and tell another person that they should think the same. When we do this, we "re-praise" the person; we praise him or her again to someone else. The word "commend" is a verb that means praise, generally indicating that the praise is being done in a formal ceremony of sorts—some sort of official praising. When we "salute," we do not necessarily make a gesture like a soldier in the military. The word "salute" can be used to describe the action of praising someone. Indeed, when a soldier "salutes" his or her general, he is recognizing and praising the authority of that person. There is at least a relation between the two uses for "salute." Since the word "commend" means recognize or praise and so does "salute," the latter is the best option given for a synonym.

"Retort," when used as a verb, means answer or reply. When used as a noun, a "retort" is an answer or a reply. The best choice is "reply," as it is a part of the definition of "retort." Considering the other choices, "conclude" means come to a decision or finish, "compose" means write, and "halt" means stop.

When something is "deceiving," it is tricky. It looks one way when, in fact, it is another thing. Thus, when we try to "deceive" someone, we try to trick that person. We attempt to make them think that one thing is true when, in fact, something else is the case. Thus, the best option here is "mislead." When we deceive someone, we "lead" them to believe the wrong thing.

When we "express" a thought, we attempt to communicate it in words as well as in bodily movements. An "expressive song" is one that has the power of communicating a message powerfully. An "expression" is a series of words communicating some kind of meaning. Thus, the best option for "express" is "communicate," for this alone focuses on the idea of making known some sort of message.

To "abuse" something is to hurt it. Something that has been "abused" has been hurt or tormented. To provide further help, "abolish" and "repeal" are synonyms - both words mean to stop, to formally discontinue. 

To "pardon" someone means to forgive them, to excuse behavior. To provide further help, "remedy" means fix, solution, solve; "quake" means tremor, shake. 

The word "acknowledge" clearly has a root of "knowledge" in it. It has to do with showing your awareness of something or someone. For example, "acknowledging a person's dignity," means, "recognizing his or her dignity." It can also mean merely to admit, as when we say, "I acknowledged that I broke the glass." This means that you admit that you broke it.
