In which examples is the person who does it (the agent) not needed? Scientists in China have discovered an unusual way of predicting earthquakes — snakes! Experts are observing snakes at local snake farms to see if their behaviour changes before an earthquake. The scientists link cameras to a broadband Internet connection. They believe that the snakes can sense earthquakes from 120 km away, three to five days before they happen. They abandon their nests or even smash into walls to escape. Because frequent earthquakes strike China, scientists must find a reliable method of predicting them to avoid the terrible injury and loss of life, they cause. *Цитирирование части задания со ссылкой на учебник производится исключительно в учебных целях для лучшего понимания разбора решения задания.

Ответ

Scientists in China have discovered an unusual way of predicting earthquakes — snakes! Snakes are being observed by experts at local snake farms to see if their behaviour changes before an earthquake. Cameras are linked to a broadband Internet connection. It is believed that earthquakes can be sensed by the snakes from 120 km away, three to five days before they happen. Their nests are abandoned or even walls are smashed into to escape. Because China is struck by frequent earthquakes, a reliable method of predicting them must be found to avoid the terrible injury and loss of life they cause.

Agent not needed: in passive sentences where the doer is unknown, unimportant, or obvious.
