Exercise 5 - Part 2
For questions 1-8, think of the best word that fits each gap. Use only one word in each gap. All answers must be in lowercase.
Animal migration stands as one of the most compelling phenomena in the natural world. Every year, millions of creatures undertake perilous journeys across vast distances, often returning to the exact spot (1) they were born. How they navigate with such astonishing accuracy remains a subject of intense scientific scrutiny. Evidence suggests that birds, for example, rely on a combination of celestial cues and the Earth's magnetic field. This internal compass is so sophisticated that even when thrown (2) course by severe storms, they can recalibrate their trajectory. (3) though it may seem, some insect species also perform multi-generational migrations, passing navigation secrets down to offspring that have (4) seen the destination. Human activity, however, poses a significant threat to these ancient routes. Climate change and urban development are disrupting habitats, making these arduous trips (5) the more hazardous. (6) no circumstances can we ignore the importance of wildlife corridors. Protecting these zones is crucial if future generations are (7) witness these spectacular seasonal journeys, which are vital for global ecological balance (8) a whole.
