What Is TOEIC® Part 5?

TOEIC® Reading Part 5 consists of 30 incomplete sentences. For each question, you must choose from 4 options (A, B, C, D) the word or phrase that correctly completes the sentence. This section primarily tests your command of English grammar and vocabulary in a professional context.

The recommended time is 10 minutes maximum, which is about 20 seconds per question. This is the section where time management is most critical: every second saved here can be reinvested in Part 7, which is far more demanding in terms of reading time.

The 4 Question Types

Understanding the different question types allows you to adapt your strategy and save time:

Type Description % of Questions
VocabularyChoose the word with the correct meaning~25%
Word FormNoun, verb, adjective, or adverb?~30%
GrammarTenses, agreement, prepositions~35%
ConnectorsLinking words (however, therefore)~10%

Strategy for Vocabulary Questions

Vocabulary questions ask you to choose the word with the correct meaning in the context of the sentence. Here is how to approach them:

  1. Read the entire sentence: Do not stop at the blank. The full context is essential for understanding the intended meaning.
  2. Identify the topic area: Is the sentence about finance, human resources, or logistics? This narrows down the vocabulary choices.
  3. Watch out for false friends: Words like eventually (in the end, not possibly), actually (in fact, not currently), or sensible (practical, not sensitive) are classic TOEIC® traps.
  4. Check collocations: Certain words naturally go together in English. For example, we say make a decision (not do a decision) and submit a report (not give a report).

Example: "The marketing team will ______ a new campaign next quarter."
(A) launch (B) open (C) start (D) begin
The answer is (A) launch because launch a campaign is the correct collocation in business English.

Strategy for Word Form Questions

These questions test your ability to identify the correct part of speech (noun, verb, adjective, adverb) needed to complete the sentence. This is often the fastest question type to solve.

  1. Look at what comes BEFORE the blank: An article (a, the) or possessive adjective (his, their) signals a noun. A verb often requires an adverb or a complement.
  2. Look at what comes AFTER the blank: If a noun follows, you probably need an adjective. If a verb follows, it is often an adverb or a subject.
  3. Master the key suffixes:
    • -tion, -ment, -ness, -ity = noun
    • -ly = adverb
    • -ive, -ous, -ful, -able = adjective
    • -ize, -ify, -en = verb

Example: "The manager provided a ______ explanation of the new policy."
(A) detail (B) detailed (C) detailing (D) details
The answer is (B) detailed because an adjective is needed before the noun explanation.

Strategy for Grammar Questions

Grammar accounts for the largest share of Part 5 questions. The most commonly tested grammar points are:

  • Subject-verb agreement: Watch out for complex subjects. "The list of items was updated" (not were, because the subject is list).
  • Tense consistency: Spot time markers (last week, next month, since, already) to determine the correct tense.
  • Conditionals: If + simple present = will + base verb. See our guide on English conditionals.
  • Passive voice: Very common in business English. "The report was submitted by the team." See our guide on the passive voice.
  • Prepositions: Prepositions are often tested with specific verbs or adjectives (responsible for, comply with). See our guide on English prepositions.

The 10 Most Tested Grammar Rules in Part 5

Here are the 10 grammar points that appear most frequently in TOEIC® Part 5. Mastering these rules will allow you to correctly answer the majority of grammar questions:

  1. Subject-verb agreement: The verb must agree with the main subject, even when other phrases come between them.
  2. Verb tenses (present perfect vs past simple): The present perfect is used for actions connected to the present; the past simple is for completed actions.
  3. Passive voice: Very common in professional contexts to emphasize the action rather than the actor. See our guide on the passive voice in English.
  4. Conditionals: Conditional structures (if-clauses) are regularly tested, especially types 0, 1, and 2. See our guide on English conditionals.
  5. Articles (a/an/the): Knowing when to use the definite article, indefinite article, or no article is essential, especially with countable and uncountable nouns. See our guide on English nouns.
  6. Comparatives/superlatives: Comparative (-er/more) and superlative (-est/most) forms are frequently tested with common adjectives.
  7. Relative pronouns (who/which/that): Choosing the correct relative pronoun depends on the type of antecedent (person, thing) and whether the clause is restrictive or non-restrictive.
  8. Prepositions of time and place: The prepositions in, on, and at are often confused. See our guide on English prepositions.
  9. Modals: Modal verbs (can, could, should, must, may, might) express ability, obligation, or possibility. See our guide on English modal verbs.
  10. Gerund vs infinitive forms: Some verbs are followed by a gerund (enjoy doing), others by an infinitive (decide to do), and some accept both with a change in meaning.

Part 5 Example Questions

Here are three TOEIC®-style Part 5 example questions to illustrate the different categories. These are not official questions, but they reflect the style and difficulty of the exam:

Example 1: Word Form Question

"The company made a ______ decision to expand into new markets."
(A) decisive (B) decisively (C) decision (D) decide

Answer: (A) decisive — An adjective is needed to modify the noun decision. The suffix -ive indicates an adjective. Decisively is an adverb (-ly), decision is a noun, and decide is a verb.

Example 2: Grammar Question

"If the report ______ on time, we can proceed with the analysis."
(A) is submitted (B) will submit (C) submitting (D) submitted

Answer: (A) is submitted — This is a type 1 conditional structure (if + present = will/can + base verb). Additionally, the report is being submitted (passive voice), so is submitted is correct. See our guides on conditionals and the passive voice for more detail.

Example 3: Connector Question

"The budget was reduced; ______, the project continued as planned."
(A) however (B) moreover (C) therefore (D) furthermore

Answer: (A) however — The second part of the sentence expresses a contrast with the first (budget reduction vs project continuation). However is the appropriate contrast connector. Moreover and furthermore express addition, and therefore expresses consequence.

Strategy for Connectors

Connectors (linking words) make up about 10% of questions, but they are predictable if you know their logical function:

Connector Function Example
howeverContrastSales increased; however, profits declined.
thereforeCause / consequenceCosts rose; therefore, prices were adjusted.
moreoverAdditionThe plan is efficient. Moreover, it is cost-effective.
neverthelessConcessionThe project was delayed; nevertheless, it was completed on time.
furthermoreAdditionThe product is durable. Furthermore, it comes with a warranty.

Tip: First identify the logical relationship between the two parts of the sentence (contrast, cause, addition), then choose the matching connector.

Time Management

Time management is critical in Part 5. You have 75 minutes for all 100 Reading questions (Parts 5, 6, and 7). Here is the ideal breakdown:

  • Part 5: 10 minutes (30 questions)
  • Part 6: 10 minutes (16 questions)
  • Part 7: 55 minutes (54 questions)

The golden rule: if you are unsure after 20 seconds, mark your best guess and move on to the next question. Never get stuck on a single question. The time saved in Part 5 is crucial for Part 7, where each passage requires careful reading.

Practical tip: start with word form questions (the fastest to solve) and save vocabulary questions for last if needed.

The Most Common Traps

Here are the 5 most common traps in Part 5, with examples to help you recognize them:

  1. Similar-looking words: affect (verb: to influence) vs effect (noun: result). "The new policy will ______ all employees." Answer: affect.
  2. Wrong word form: economic (adjective: relating to the economy) vs economical (adjective: cost-effective). "The company adopted a more ______ approach." Answer: economical.
  3. Tense traps: Present perfect with since or for. "She has worked here ______ 2015." Answer: since (not for, because 2015 is a point in time).
  4. Collocation errors: make vs do. "The team needs to ______ a presentation." Answer: make (the correct collocation is make a presentation).
  5. Double-meaning words: current can mean "present" or "electrical flow." "Please review the ______ budget." Answer: current (present). Context is key.
