Previous Year Question

Statement 1 is correct. AI can analyse sensors and operational data in industrial units to forecast energy demand. It helps reduce electricity consumption and energy wastage by optimising the operation of machinery, heating, cooling, lighting and production schedules. Inefficient equipment can also be identified through predictive maintenance.

Statement 2 was not considered correct at that time. In 2020, AI could generate text and music, but reliably creating meaningful stories and songs with consistent meaning, human emotion and creativity was not considered an effective and mature capability.

Statement 3 is correct. AI can assist doctors in identifying and diagnosing diseases by analysing patterns in medical images, laboratory data and clinical records. For example, it is used in the screening of diabetic retinopathy, cancerous lesions and radiological abnormalities. AI is not automatically a complete substitute for a doctor; its safe use requires clinical validation and human oversight.

Statement 4 is correct. Text-to-Speech technology converts written text into synthesised human-like speech. AI and deep neural networks improve pronunciation, rhythm, tone and naturalness. It is used in screen readers, virtual assistants, navigation systems and accessibility tools.

Statement 5 is incorrect. Wireless transmission of electrical energy is based on physical principles such as electromagnetic induction, resonant coupling, radio waves or microwaves. AI may control or optimise these systems, but the wireless transmission of energy is not itself a function of AI.
