Something that is "blatant" is easily observable. Something that is easily observable is often "obvious" because it would be difficult not to see. Therefore, "obvious" is the best answer. The other answer choices have meanings unrelated to "blatant": "brave" means demonstrating courage; "scary" means causing one to feel afraid; and "disagreeable" means unpleasant or horrible.

The word "partial" comes from the root "part." A "partial" action is one that only completes part of the total action to be performed. Sometimes, the word is extended to mean something akin to "only seeing and/or acknowledging part of reality." This is means that someone is "biased" or favors one thing over another, though perhaps without a good reason—or at least one that he or she can explain. The word "prejudiced" means having an opinion without really knowing all of the details. The word literally comes from the suffix "pre-," meaning before, and "-judiced," which is related to "to judge." A prejudice "pre-judges" a matter before all the facts have been presented. Someone who is "partial" can (in some circumstances) be called "prejudiced."

Both of the meanings of the word "prone" in English derive from a Latin root meaning "leaning forward." In a physical sense, this leads to the meaning of lying face down (now popularly called "planking"), and in a less-literal sense—as in this question—it can mean having a tendency toward something. One might be prone to anger, or prone to speak out of turn in class. The word "wont," (which is a homophone of the more-familiar word "want"), also means to be inclined toward something.

"Onerous" is an adjective that means "involving an amount of effort or difficulty that is overly burdensome." Fun is clearly incorrect, as is talented. So scary sounds possible, since onerous looks a little like ominous, but just because something is challenging does not make it scary, so that's out. Rude is close, and onerous can certainly be used in a context that might mean rude, but ultimately, difficult is the closest synonym.

"Susceptible" means in danger from something specific or vulnerable to something. To help you, "impregnable" means not able to be broken into, "tempestuous" means passionate and emotional, to "harangue" someone means to lecture, berate, or criticize him or her, and "quixotic" means idealistic and impractical.

"Arduous" means challenging and/or causing strain. Something that is "difficult" is hard to accomplish. Thus, "difficult" is the best synonym of "arduous." While "ardent" may seem like a tempting answer, as it sounds similar to the word "arduous," it means passionate, which is very different in meaning than the definition of "arduous."

The word "peckish" is an adjective that means slightly hungry. The best choice is "hungry" because it is part of the definition of "peckish." "Famished" (incredibly hungry) is too strong of a word to be a better synonym of "peckish" than "hungry" is, and "parched" (extremely thirsty) is too distant in meaning to be the correct answer. Considering the other answer choices, "full" means abundant and "mottled" means spotted.

"Labor" means work, so it makes sense that “laborious” means involving hard work, or "difficult." “Mundane” means boring or ordinary; “mediocre” means average when higher quality was expected; and "overt" means obvious or easy to notice.

Resistant. Impervious most nearly means, impenetrable and impassable. Something that is "impervious" is resistant to certain or all things. For instance, a sentence using the word would be "He was impervious to her reasoning."

Most of the other choices are antonyms, with the exception of "nervous" which is unrelated.

The word "disparate" means unequal or uneven. The best choice is "uneven," as it is a part of the definition of "disparate." Considering the other choices, "delayed" means put off to a later time, "cold" means having a relatively low temperature, and "bombastic" describes language and means sounding impressive but not actually meaning much.
