The doctors … Bola's grandmother after the heart attack.

Step 1: Analyze the question The sentence is: "The doctors ..... Bola's grandmother after the heart attack." We need the word that describes what doctors do to bring someone back to life or consciousness after the heart stops or fails.

Step 2: Understand each option

• A. resuscitated: to revive someone from unconsciousness or apparent death, especially by medical techniques such as CPR, defibrillation or oxygen. This is the standard medical term.
• B. regenerated: to grow back or renew, e.g. tissue, a forest, or an economy. It doesn't fit a person recovering from a heart attack.
• C. revivified: to give new life or vigour to something. It is rare and literary, and not the usual medical term.
• D. resurrected: to bring back from the dead, in a religious or miraculous sense (e.g. the resurrection of Jesus). Doctors don't resurrect people, since resurrection means returning after being truly dead.

Step 3: Choose the best fit The context is medical (doctors, heart attack), and the most precise word for restoring a person's breathing or heartbeat is resuscitated.

Answer: A. resuscitated

Exam tip: Link the word to its context.

• Resuscitate goes with doctors, CPR and emergencies.
• Resurrect goes with religion or bringing back something long dead (e.g. "resurrect an old tradition").
• Regenerate goes with growth and renewal.

In "best completes the sentence" questions, always pick the word that matches the setting, not just one that sounds close in meaning.
