Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 27 to 34.

In recent decades, rapid advancements in science and technology have profoundly reshaped modern life from household management to healthcare and urban development.

Scientific and technological innovations have become inextricably integrated in daily life, fundamentally transforming how individuals perform routine activities. Smart systems, powered by artificial intelligence and interconnected infrastructures, enable users to regulate domestic functions such as illumination, thermal conditions, and security with remarkable precision. By assimilating data from disparate sources, these systems generate adaptive environments that respond dynamically to users’ behavioural patterns.

A prominent application can be observed in energy optimisation. Sophisticated monitoring devices allow households to analyse consumption patterns and adjust usage accordingly. Certain appliances are programmed to operate during off-peak intervals, while surplus energy derived from renewable sources may be conserved for subsequent utilisation.Consequently, overall efficiency is augmented, although the amount of money saved may fluctuate depending on consumption habits.

Technological advancements have also redefined healthcare practices. Wearable devices continuously register physiological indicators, including heart rate variability and sleep quality, transmitting such data to digital platforms for comprehensive analysis. These systems are capable of detecting anomalies and issuing early alerts, thereby enabling users to undertake preventive measures before minor conditions deteriorate. Nevertheless, their efficiency remains contingent upon users’ responsiveness to the feedback provided.

Furthermore, smart urban infrastructures have enhanced the administration of public systems. Real-time data collected from sensors embedded in transport networks facilitate the optimisation of traffic flow and the mitigation of congestion. While such systems cannot entirely eradicate delays, they substantially enhance efficiency and alleviate environmental impact. These developments underscore the role of technology in fostering sustainable and manageable urban environments.

In conclusion, technological innovations continue to play a vital role in improving various aspects of human life. While they offer substantial benefits in efficiency, healthcare, and urban management, their limitations highlight the need for responsible and effective use to maximise their potential.
