• Sentence (i) is correct. The expression “interfere in someone’s personal affairs” is grammatically acceptable.
• Sentence (ii) is incorrect because personal is an adjective meaning private or relating to a person. The correct noun is personnel, which means the employees or staff of an organization.

• A one-eyed person
• An honest man (honest starts with a vowel sound)
• An hour (hour has a silent h)

Explanation: The prefix dis- is added to embark to form disembark, which means to leave or get off a ship, aircraft, train, or other vehicle.

Exam Tip: Common prefix pairs:

• Embark ↔ Disembark
• Appear ↔ Disappear

• Honest ↔ Dishonest

Explanation: To change a declarative sentence into an interrogative sentence, place the auxiliary verb is before the subject honesty. This forms a simple yes/no question without changing the meaning.

Exam Tip: For sentences containing am, is, are, was, were, has, have, had, will, can, should, simply move the auxiliary verb before the subject to form an interrogative sentence.

• He is ready. → Is he ready?
