Reading Comprehension

Passage: Healthcare innovation has accelerated dramatically in recent decades, transforming medical diagnosis, treatment, and prevention. Breakthroughs in genomics have enabled personalised medicine, where treatments are tailored to individual genetic profiles. Telemedicine has expanded access to healthcare, particularly in remote areas, while artificial intelligence is being deployed to analyse medical images and predict patient outcomes with increasing accuracy. Despite these advances, significant challenges remain. Healthcare costs continue to rise, creating barriers to access for many populations. The development of new pharmaceuticals is increasingly expensive, with some treatments costing hundreds of thousands of dollars. Disparities in healthcare outcomes persist along socioeconomic and geographic lines. Ethical questions about gene editing, data privacy, and the appropriate use of AI in medical decision-making continue to provoke debate. As healthcare systems worldwide grapple with ageing populations and chronic disease burdens, balancing innovation with accessibility and equity remains a critical challenge.
