1. Sample Text 1 — Artificial Intelligence

Artificial intelligence refers to computer systems designed to perform tasks that normally require human intelligence, such as recognising speech, identifying images, translating languages, and making decisions. Modern AI systems are typically trained on large datasets using machine learning algorithms that identify patterns and adjust their parameters to improve performance over time.

Incorrect words — audio says: “written” not “designed”; “huge” not “large”; “change” not “adjust”

2. Sample Text 2 — Tectonic Activity

Earth’s surface is divided into large tectonic plates that move slowly across the mantle, driven by convection currents of heat from the planet’s interior. Where plates collide, mountains form or one plate is forced beneath the other in a process called subduction. Earthquakes and volcanic eruptions occur most frequently along these boundaries.

Incorrect words — audio says: “crust” not “surface”; “thermal” not “convection”; “pushed” not “forced”
