TOEFL Preparation Quiz: Structure

“Be replaced” is correct because “scheduled to” must be followed by an infinitive form. Since the security door receives the action, the passive infinitive is needed. The sentence describes a planned maintenance action, not something the door will do itself. Therefore, “be replaced” is the only grammatically correct and meaningful choice in this workplace notice.

“Due to” is correct because it clearly shows the reason for the early closing. The holiday weekend is the cause of the schedule change. The other options do not express cause properly in this sentence. In workplace announcements and notices, “due to” is commonly used to explain closures, delays, or changes in operating hours.

“Succeed” is correct because it means to take over a position after someone leaves it. The sentence refers to Adam Lopez replacing Tom Green if Tom resigns. The other choices do not match this leadership or job-transition meaning. In business English, “succeed someone” is the standard verb for following another person in a position.

“More than” is correct because it modifies “doubled” to show the increase exceeded two times the original amount. The sentence is about financial growth, and “has more than doubled” is a natural business expression. The other options do not fit grammatically or logically before “doubled,” so they fail to express the intended degree of increase.

“Consecutive” is correct because it means following one after another without interruption. The sentence describes five quarters in a row with lower net income. This is common financial reporting language. The other words do not accurately describe uninterrupted sequence, so they do not fit the meaning needed in a business performance statement.

“Distribution” is correct because it completes a logical list of business functions: manufacture, sale, and distribution. These are parallel nouns that describe how a company produces and delivers products. The other options do not fit the meaning of appliance operations. “Distribution” is the only choice that matches both the grammar and the business context.

“All” is correct because the instruction tells the reader to follow every step on the first page. Technical directions usually require full compliance, not partial action. “Most of,” “much,” and “almost” do not work naturally before plural countable noun “steps” in this context. The sentence needs a complete and direct instruction, which “all” provides clearly.

“In exchange for” is correct because it shows what volunteers receive in return for their work. They give time and labor, and they receive food and accommodation. This phrase is commonly used when describing mutual arrangements. The other options are ungrammatical or unnatural, so they do not properly express the idea of compensation.

“Tickets” is correct because the sentence refers to multiple admission passes that are valid for the Auto Show. The adjective “discounted” naturally modifies a plural noun here. The other choices are incorrect word forms. In event and sales language, “discounted tickets” is the standard and most natural expression for reduced-price admission.

“Convinced” is correct because it functions as an adjective after the linking verb “are.” The sentence expresses confidence that the project will succeed. “Convincing” describes something persuasive, “convinces” is a verb, and “convincement” is not standard usage. “Be convinced that” is a common business structure for expressing strong belief or certainty.

“Introducing” is correct because it follows “will be,” which requires the present participle for an ongoing future activity. The sentence describes what companies will do at their booths during the event. The other forms do not fit the tense structure. This is a standard way to describe planned activity at exhibitions and trade shows.

“Of” is correct because the fixed expression is “take advantage of.” It means to benefit from something, in this case a discount. The other prepositions do not form the correct idiom. Business English relies heavily on accurate verb-preposition combinations, and “take advantage of” is the only accepted phrase that fits this pricing sentence.

“Being made” is correct because the sentence is passive and describes action currently in progress. The focus is on the efforts, not on who is making them. “Is being made” is the correct passive continuous structure. The other options do not complete the verb phrase correctly, so they fail grammatically in this workplace problem-solving statement.

“Through” is correct because it expresses the method by which children learn. The philosophy says learning happens through hands-on activities, meaning by means of active involvement. The other options do not fit naturally here. In educational writing, “learn through experience” and similar patterns are common for describing practical or activity-based learning approaches.

“Separately” is correct because it means the invoices are sent apart from the book orders. The sentence contrasts the normal procedure with an exception requested by the buyer. “Jointly,” “diversely,” and “partially” do not match that meaning. In order processing and billing, “sent separately” is a standard phrase used to describe separate documentation.
