TOEIC Grammar & Vocabulary — Sentence Completion

"Throughout" is the correct preposition because it indicates the delay lasted for the entire duration of the monsoon season. "While" requires a clause, "despite" signals contrast, and "until" would imply the delay ended at a specific point rather than spanning the whole period.

A sentence adverb is needed to modify the entire clause. "Regrettably" correctly expresses that the outcome is unfortunate from an objective standpoint. "Regretfully" implies the subject personally feels regret, which doesn't fit here. "Regrettable" and "unfortunate" are adjectives and cannot open a clause this way.

"Selection" best fits because it refers to a curated range of available items. "Choice" typically implies an act of choosing rather than the available set. "Option" refers to a single alternative, and "preference" describes a personal inclination rather than what is on offer.

"As well as" correctly joins two parallel elements — technical writing and presentation skills — indicating both are included. "Either" and "rather" require different constructions, and "instead" implies one replaces the other, which contradicts the meaning.

"Upon" signals that the warranty activates immediately after a specific trigger — registering the product. "Until" implies waiting, "unless" introduces a negative condition, and "toward" indicates direction, none of which are appropriate here.

"Even though" introduces a concessive subordinate clause, acknowledging the early completion while noting the client's additional requests. "Despite of" is grammatically incorrect — the correct form is "despite" followed by a noun phrase. "Nevertheless" and "however" are conjunctive adverbs that connect independent clauses, not introduce subordinate ones.

"From" indicates the source material — the brass was transformed into the clock. "Of" is used for general composition (e.g., "made of brass") but "crafted from" specifically highlights origin and transformation. "With" suggests a tool, and "by" indicates an agent.

"In" correctly indicates a future point in time — the meeting will happen after two weeks have passed. "For" indicates duration, "at" is used for specific clock times, and "by" implies a deadline rather than a scheduled occurrence.

A noun is required after the determiner "utmost." "Confidentiality" correctly fills this role as it refers to the quality of keeping information private. "Confidential" is an adjective, "confident" relates to self-assurance, and "confidentially" is an adverb — none of which can follow "utmost" in this construction.

"Those" is used to refer back to "sales figures" — a plural noun that is distant or previously mentioned. "These" refers to something nearby or just introduced, "them" is an object pronoun and cannot replace a noun in a comparative structure, and "it" is singular.

An adverb is needed to modify the adjective "larger." "Considerably" correctly intensifies the comparison. "Considerable" is an adjective, "consideration" is a noun, and "considerate" means thoughtful toward others — none of which can modify an adjective in this context.

"Either in... or" is the correct paired conjunction structure here, presenting two storage options. "Between" and "among" are prepositions used for positional relationships, not choices. "Both in" would require "and," not "or," and would imply both locations must be used simultaneously.

"Until" correctly expresses that approval is withheld pending a specific condition — independent verification of the projections. "Since" indicates a reason or starting point, "while" indicates simultaneity, and "as soon as" would imply approval happens immediately upon verification, reversing the conditional meaning.

"Although" introduces a concessive clause, acknowledging the positive reception while noting a reservation. "Because" indicates cause, "therefore" signals a conclusion, and "so that" expresses purpose — none of which capture the contrast intended here.

"Applicable" is the correct adjective here, meaning the regulations apply to everyone. "Applied" is the past tense verb form, "application" is a noun, and "applying" is a present participle — none of which fit the predicate adjective slot after the linking verb "are" in this sentence.
