The general idea of this sentence is that the development of robotics is viewed by some as being a bad thing. Thus, it is viewed as being detrimental to human well-being.

Since she made the effort to add to the outfit, we can assume the basic outfit was neither “sublime” nor “plush.” “Sophistries” sounds similar to “sophisticated,” but it is actually a fallacious method of reasoning. “Wanting . . . accessories” is the correct response.

Note that “inconsiderable” is not synonymous with “considerable.” “Inconsiderable” means it is not worth considering or noticing. To find the correct answer, we must check both words to see if they render a cogent sentence. “Acclivity” is an upward slope. “Laborious” means it requires a lot of work. These two words logically combine to give us the best answer.

A “denunciation” is a public reprimand, so it doesn’t fit with the clues of “fine service” or “highly classified.” “Conspicuous” and “monumental” can likewise be eliminated. An “accolade” is an award or honor. “Clandestine” means done in secret. Together, these form the correct answer.

"Usage . . . unexpected" makes sense. Usage is one of the nouns that makes sense in the context of DVDs. The word "random" further solidifies that strength of this choice; the earlier adverb "unexpectedly" makes "random" a clear choice.

A “neophyte” is a beginner, which wouldn’t make sense given the context. An “optimist” takes a favorable view of an outcome. “Reluctant” or “uncertain” would be the right choice if the sentence had started with “since” instead of “despite.” “Adamant . . . skeptics” is the correct answer.

“Dudgeon” means a feeling of indignation. A “mainstay” is a supporter. “Paltry” and “diminutive” don’t work as well as the other three options since a small amount of research would be associated with a disinterest or disbelief in the subject, and there is a sentence shift after the word “only.” “Exorbitant . . . addendum” is the correct answer.

“Sequestered” is similar to “remote” in that it refers to providing privacy or seclusion. If seeing inside the kitchen was easy, we can assume neither of these words apply. “Somnambulism” and “noctambulism” are synonymous with sleepwalking. “Adjoining . . . somnambulism” is the correct response.

“Obsequious” describes acting in a servile manner, but almost overly so. An obsequious person could easily be called a “teacher’s pet.” An “adjutant” is often someone who serves as an assistant to someone of higher rank, like a general; but it can also be used to describe a loyal follower in a classroom. “Obsequious . . . adjutant” is the correct answer.
