Section E: Spot the Error

C — Assistive technologies are used in homes, schools, workplaces and public spaces — not only in hospitals and clinics. They support people with disabilities in any setting where they need help to perform tasks. Line 2 is wrong.

B — GPS does not require an internet connection to determine location — it uses signals from satellites in orbit. An internet connection may be needed to download maps but is not required for the GPS positioning itself. Line 1 is wrong.

A — Robots can be programmed with decision-making logic to respond to sensor data and changing conditions. Modern robotic systems use software to make real-time decisions about how to perform tasks. Line 0 is wrong.

D — Digital financial systems serve individuals, small businesses and large organisations alike. Mobile banking apps, payment platforms and investment tools are all available to individual users, not only large banks. Line 3 is wrong.

C — Traffic management systems control far more than pedestrian crossings — they manage traffic lights, variable speed signs, tunnel ventilation, incident detection and overall vehicle flow on roads and motorways. Line 2 is wrong.
