  1. 1. Grammar & Sentence Structure

    The number of applicants ___ increased sharply this year. Which choice is correct?

    • a.has
    • b.have
    • c.are
    • d.were

    Answer: a

    Explanation: The phrase 'the number of' is treated as singular, so it takes the singular verb 'has'. (By contrast, 'a number of applicants have' would be plural.)

  2. 2. Grammar & Sentence Structure

    If it ___ tomorrow, we will cancel the outdoor event. Which choice is correct?

    • a.will rain
    • b.would rain
    • c.rains
    • d.rained

    Answer: c

    Explanation: This is a first conditional about a real future possibility. The 'if' clause uses the present simple 'rains', while the main clause uses 'will cancel'.

  3. 3. Grammar & Sentence Structure

    He enjoys reading, writing, and ___. Which choice keeps the sentence parallel?

    • a.painting
    • b.to paint
    • c.paints
    • d.painted

    Answer: a

    Explanation: Items in a series must share the same grammatical form. Since 'reading' and 'writing' are gerunds, the third item must also be a gerund: 'painting'.

  4. 4. Vocabulary in Context

    His ___ remarks offended several guests at the dinner. Which word best fits?

    • a.gracious
    • b.timid
    • c.tactless
    • d.fluent

    Answer: c

    Explanation: 'Tactless' means lacking sensitivity, which explains why the remarks offended people. 'Gracious' would mean kind and polite, contradicting the result.

  5. 5. Vocabulary in Context

    The new medication helped ___ the patient's pain within minutes. Which word best fits?

    • a.alleviate
    • b.aggravate
    • c.ignore
    • d.prolong

    Answer: a

    Explanation: 'Alleviate' means to relieve or lessen, which fits reducing pain. 'Aggravate' means to make worse, and 'prolong' means to extend, both contradicting the context.

  6. 6. Word Forms & Collocations

    She answered every question with great ___. Which word form is correct?

    • a.confident
    • b.confidently
    • c.confide
    • d.confidence

    Answer: d

    Explanation: After 'with great', a noun is required. 'Confidence' is the noun; 'confident' is an adjective and 'confidently' is an adverb.

  7. 7. Word Forms & Collocations

    The samples were ___ examined before the results were published. Which word form is correct?

    • a.thorough
    • b.thoroughly
    • c.thoroughness
    • d.more thorough

    Answer: b

    Explanation: An adverb is needed to modify the verb 'examined'. 'Thoroughly' is the adverb; 'thorough' is an adjective and 'thoroughness' is a noun.

  8. 8. Connectors & Cohesion

    She prepared for months; ___, she passed the interview with ease. Which connector fits best?

    • a.however
    • b.otherwise
    • c.instead
    • d.consequently

    Answer: d

    Explanation: The second clause is a result of the first, so a cause-and-effect connector is needed. 'Consequently' correctly signals the result of the preparation.

  9. 9. Connectors & Cohesion

    The proposal is expensive. ___, it could generate substantial long-term savings. Which connector fits best?

    • a.Therefore
    • b.However
    • c.Thus
    • d.Hence

    Answer: b

    Explanation: The second sentence contrasts the cost with a benefit, so a contrast connector is needed. 'However' introduces that contrast; 'therefore', 'thus', and 'hence' all show results.

  10. 10. Common Usage Errors

    We need ___ chairs than we currently have for the event. Which choice is correct?

    • a.less
    • b.lesser
    • c.little
    • d.fewer

    Answer: d

    Explanation: 'Chairs' is a countable noun, so 'fewer' is correct. 'Less' is used with uncountable nouns, such as 'less water'.
