Select the most appropriate title for the given passage.

Concept

A strong passage title captures the central subject and the overall direction of the whole passage. It should cover the beginning, development, and conclusion without adding a claim that the passage does not make.

Application

The passage traces lobotomy from its creation and early popularity through its harmful effects, decline, and present-day ethical judgment. That complete arc concerns lobotomy’s historical impact on mental-health treatment.

Contrast

• “Understanding Lobotomy’s Permanent Popularity in Psychiatry” conflicts with the passage’s statement that its use declined and that it is now considered outdated.

• “Examining Lobotomy’s Role in Enhancing Cognitive Abilities” introduces an effect the passage contradicts by describing impaired thinking among patients.

• “Exploring Lobotomy’s Contribution to Modern Neurosurgery” adds a modern-neurosurgery focus that the passage does not develop.

Result

“Investigating Lobotomy’s Historical Impact on Mental Health” is the most appropriate title because it covers the passage’s full historical arc without introducing an unsupported claim.
