- 1. Grammar & Sentence Structure
The number of applicants ___ increased sharply this year. Which choice is correct?
- a.have
- b.are
- c.has
- d.were
Answer: c
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. Grammar & Sentence Structure
If it ___ tomorrow, we will cancel the outdoor event. Which choice is correct?
- a.rained
- b.would rain
- c.rains
- d.will rain
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. Grammar & Sentence Structure
He enjoys reading, writing, and ___. Which choice keeps the sentence parallel?
- a.painted
- b.painting
- c.paints
- d.to paint
Answer: b
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. Vocabulary in Context
His ___ remarks offended several guests at the dinner. Which word best fits?
- a.timid
- b.gracious
- 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. Vocabulary in Context
The new medication helped ___ the patient's pain within minutes. Which word best fits?
- a.alleviate
- b.ignore
- c.prolong
- d.aggravate
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. Word Forms & Collocations
She answered every question with great ___. Which word form is correct?
- a.confidently
- b.confident
- c.confidence
- d.confide
Answer: c
Explanation: After 'with great', a noun is required. 'Confidence' is the noun; 'confident' is an adjective and 'confidently' is an adverb.
- 7. Word Forms & Collocations
The samples were ___ examined before the results were published. Which word form is correct?
- a.thoroughly
- b.thorough
- c.thoroughness
- d.more thorough
Answer: a
Explanation: An adverb is needed to modify the verb 'examined'. 'Thoroughly' is the adverb; 'thorough' is an adjective and 'thoroughness' is a noun.
- 8. Connectors & Cohesion
She prepared for months; ___, she passed the interview with ease. Which connector fits best?
- a.however
- b.otherwise
- c.consequently
- d.instead
Answer: c
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. Connectors & Cohesion
The proposal is expensive. ___, it could generate substantial long-term savings. Which connector fits best?
- a.However
- b.Thus
- c.Therefore
- d.Hence
Answer: a
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.

We need ___ chairs than we currently have for the event. Which choice is correct?
- a.little
- b.fewer
- c.less
