We called the carpenter to repair the broken door.

Analyze the question: The underlined word is repair, as in "We called the carpenter to repair the broken door." We need the word closest in meaning to it in this context.

Explain the concept: Repair means to fix something that is damaged or broken so that it works or looks right again. Many words overlap with it, so you must pick the one that fits the sentence best.

Go through the options:

• A. restore: This means to bring something back to its original condition, usually something old or worn, like restoring an antique or old building. It is not the everyday word for fixing a broken door.
• B. renovate: This means to improve or modernize something, usually a whole building or room, so it is not just fixing a break.
• C. replace: This means to take away the broken thing and put a new one in its place. Repairing a door is not the same as getting a new door.
• D. mend: This means to fix something broken or damaged. It is the closest synonym to repair.

Answer: The best match is D. mend.

Tip: In synonym questions, test each option by putting it into the sentence. "We called the carpenter to mend the broken door" keeps the meaning exactly. Also watch for distractors that sound similar but mean something bigger (renovate) or different (replace).
