"Ubiquitous" is defined as present, appearing, or found everywhere; thus, "everywhere" is the best answer choice.

“Lofty” means high up when referring to physical location, or noble when referring to ideas, so "high" is the correct answer. To provide further help, “narrow” means thin in width; “excessive” means too much; and “serene” means quiet and peaceful. 

"Maritime" is an adjective that means "connected with the sea, especially in relation to seafaring commercial or military activity," "living or found in or near the sea," "bordering on the sea," or "denoting a climate that is moist and temperate owing to the influence of the sea." While "wet" might look like the correct answer because both "wet" and "maritime" can be associated with water, "wet" does not mean the same thing as "maritime" and cannot be the correct answer. "Nautical," however, means "of or concerning sailors or navigation; maritime," and because it is the answer choice closest in meaning to "maritime," "nautical" is the correct answer.

The adjective "prior" indicates that something comes before another thing. For instance, if you already have some knowledge of frog anatomy when your class begins to cover this subject, your biology teacher could say that you have "prior knowledge." The word "prior" is opposed to the word "posterior," which means coming after. A "prior commitment" is a commitment or meeting that you have scheduled at an earlier point in time. While things like "prior knowledge" might be simple in comparison with later developments of that knowledge, the best option among the answers is the one that draws attention to the general notion of being "before." Hence, "preceding" is the best option, for "preceding" means coming before.

"Exterior" means outside.

The word “urban” means having to do with the city or life in the city as opposed to the country and life in the country, so "metropolitan" is the correct answer, since it means having to do with a metropolis, or in other words, having to do with a large city. The word “rural,” on the other hand, means having to do with the countryside or life in the country. To provide further help, the “coast” is the border between the land and a large body of water or the area near this border.

The adjective "cosmic" refers to something in the sky. "Heavenly" and "angelic" are closely related in meaning. "Above" is the opposite of "under," which is the root of the word "underground." The word "underground" is closest in meaning to the word "buried."

We can arrive at the correct answer using process of elimination. The words "quick" and "speedy" both mean exactly the same thing. They refer to something that is fast. Both of these words cannot be the correct answer, so it is best to eliminate these two choices. The word "first" means the opposite of "last." The word "foremost also means first; consider the common expression "first and foremost." This only leaves the word "final." "Last" and "final" are synonymous.

The words "inward" and "inside" are synonymous; both words are used to describe a direction headed to the interior of something. "Underground" refers to something that is under the ground. The words "outside" and "outdoor" mean the same thing. And the word "open" refers to something that is "accessible."

"Laconic" means concise and to the point, using few words.
