The proprietor has promised to … the dilapidated classroom blocks.

Analyze the question The sentence is about "dilapidated classroom blocks". We need a verb that fits buildings that are old, run-down, and falling apart.

Explain the concept "Dilapidated" means in a state of disrepair or ruin because of age or neglect. The best verb is one that means to restore or repair something that already exists, so that it becomes good again.

Check each option

• A. erect means to build or put up something new. It does not suit blocks that already exist, so it is wrong.
• B. renovate means to restore an old or damaged building to good condition. It fits perfectly.
• C. patch means to mend a small hole or damaged spot, usually temporarily. It is too minor for whole dilapidated blocks, and a proprietor "promising" to do a big job suggests something more complete.
• D. fabricate means to manufacture or make up (a story, a lie). It is not used for repairing buildings.

Answer The sentence reads: "The proprietor has promised to renovate the dilapidated classroom blocks."

Tip Link words to their partners: dilapidated goes with renovate, repair, or rehabilitate. Remember the prefix re- in renovate means "again", so it means "make new again". On the exam, ask yourself whether the thing already exists (renovate) or is being built from nothing (erect).
