If something is benign such as the weather, it indicates that it is mild. In the case of weather, benign conditions are the opposite of inclement weather.

When used as a noun, "pedestrian" means "a person walking along a road or in a developed area." When used as an adjective, however, "pedestrian" means "lacking inspiration or excitement; dull." "Thrilling" cannot be the correct answer because "thrilling" is an antonym of "vim," and while "languid" may seem close in meaning to "pedestrian," "languid" means "displaying or having a disinclination for physical exertion or effort; slow and relaxed" when describing a person, manner, or gesture, "pleasantly lazy and peaceful" when describing an occasion or period of time, or "weak or faint from illness or fatigue." "Uneventful," an adjective that means "not marked by interesting or exciting events," is the closest synonym to "pedestrian" amongst the listed answer choices, so "uneventful" is the correct answer.

The definition of "mundane" is everyday or ordinary, making "common" the only possible choice.

When something is banal, it is extremely overused and has little meaning because of that. For instance, one might speak of a “banal phrase” that is really nothing but empty words or “banal song lyrics” that really express no meaning at all. When something is “vapid,” it does not stimulate at all. The word “vapid” comes from the Latin for “flat” or “tasteless.”

Among your options, it might be tempting to choose “unreliable”; however, the closest meaning for “erratic” is “irregular” or unpredictable. The word comes originally from the Latin meaning to stray or wander. When someone “errs,” he or she might make a mistake, but the strict sense is that person “goes the wrong way.” Someone might be “unreliable” because they are erratic; however, that is only because that person is irregular or unpredictable. Because they are so, they are thus unreliable.

The word “edifying” is related to the English “edifice,” meaning building. Most strictly, “to edify” means to improve someone intellectually or morally. It is often used in the sense of “improvement” in general, though this is a secondary usage. Bearing this qualification in mind, “improving” is still the best option among those given. One can speak of “edification” when describing the instruction itself, as in, “He provided edification to the young man in order to improve his moral behavior.”

We tend to think of “deviant” as used in the phrase “social deviant.” This is often applied to people (perhaps problem-causing children) who are involved in activities that society frowns upon. This usage must not lead us to think that “deviant” means one who does illegal things. It is better understood from the perspective of the word “deviate,” which means to stray beyond the norms. When something is an anomaly, it is just this, namely something that goes away from the norm.

The word “myriad” is derived from the Greek for "10,000." In general, it is used to describe a countless multitude of things. For that reason, the best option among the provided answers is “innumerable.” An example usage would be, “Roger wished to do something so foolish that his friends were able to provide him with myriad reasons, overwhelming him with reasons for making such a stupid choice.”

The word “trite” is often used in expressions like “his trite, meaningless remarks” or “the phrase was rather trite and common.” It often implies that something is insignificant or not important, but this sense follows on the main meaning of the word, namely, overused. It applies to expressions and ideas that have been repeated so often that they have lost their force. They become common knowledge and seem rather uninformative—“everyone knows that trite truth.” Among the options given in the answers, “clichéd” is the best, as it means overused and unoriginal.

You might be more familiar with the word “platitude” than with “platitudinous.” The former is the related noun form of the same base. A “platitude” is an expression, often moral in nature, that has been so overused that it has lost its meaning. You might know someone who recites such expressions as, “Everything happens for a reason.” Such remarks either tell you nothing or often just frustrate you when horrible things happen. They provide little consolation or direction. Although a “platitudinous” expression could be called “annoying,” it is most properly said to be something “overused.” The annoyance follows on the fact that overuse has totally shorn it of its meaning and significance.

The word “prodigious” is related to the same root word as “prodigy,” which is often used to describe a person who has great skills. For instance, many people talked of Mozart as a “child prodigy” because he could play the piano with great skill at a young age. When something is “prodigious,” it is impressive, magnificent, or at least grand in scope or degree. Among the options provided, “monumental” best captures this sense.

The word “prolific” comes from the Latin for “bearing offspring.” When an animal is “prolific” it bears much fruit or many children. When an artist is prolific, he or she produces many works. An example sentence would be, “The old man had been a prolific author during his lifetime, writing over a hundred best-selling thriller novels.”

"Tantamount" means the same or identical and is typically found in the phrase "X is tantamount to Y." That makes "same" the correct answer; as for the other answer choices, "stringent" means rigid or tight; "ironic" means coincidental or unexpected; "bubbly" means lively or energetic; and "cryptic" means secret or obscure in meaning.

Originally used to describe beverages lacking in flavor, "vapid" came to describe anything that is dull or insipid.

"Aesthetic" describes something having to do with beauty. Be careful not to confuse it with similar sounding words like "ascetic" (harshly disciplined) or "aseptic" (sanitary).

Something that is "garish" is excessively and crudely showy. "Gaudy" carries the same sense of being tastelessly flashy. "Modest" is an antonym.

"Wretched" and "deplorable" both mean terrible or miserable. "Reassuring" means bolstering or cheerful. "Willful" means stubborn or obstinate. "Wary" means careful or cautious. "Queasy" means uncomfortable or fidgety.

"Tawdry" and "tacky" both mean cheap or tasteless. "Sophisticated" means refined or elegant. "Nebulous" means confused or obscure. "Taciturn" means uncommnicative. "Urbane" means cosmopolitan or sophisticated.
