HIGH-TECH EAVESDROPPING ON THE GANGES RIVER DOLPHIN SONAR SIGNALS HOLD CLUES THAT COULD SAVE AN ENDANGERED SPECIES
The Ganges river dolphin is one of only two remaining freshwater dolphin species on Earth. But pollution, fishing, and dams threaten to wipe it out entirely. So acoustical engineer Harumi Sugimatsu and her team have deployed an experimental sonar monitoring system just under the surface of the murky water. The hope is to track the dolphins by the high-frequency clicks they use to navigate and hunt. By eavesdropping on their underwater lives, Sugimatsu believes she can gather data about their behavior and geographical range—data that conservationists can use in their struggle to keep the species from going extinct.

Why is the word eavesdrop used?
Gabarito:
Because dolphins seem unaware of the interception of communication.
Resolução:
A palavra "eavesdrop" significa bisbilhotar/ouvir por acaso e foi usada no texto porque os golfinhos parecem não ter consciência da interceptação de comunicação, o que está de acordo com a alternativa E) Because dolphins seem unaware of the interception of communication. Portanto, bisbilhotando a vida dos golfinhos debaixo d'água, Sugimatsu acredita poder conseguir informações necessárias para impedir a espécie de extinção.
As outras alternativas estão incorretas.
A) Porque as pesquisas vão ser capazes de manter as espécies que vivem no Ganges.
B) Porque cientistas e golfinhos podem se rastrear través da água turva.
C) Porque golfinhos podem se comunicar e indicar a presença de cientistas.
D) Porque pesquisadores precisam lidar com obstáculos.
