Texto 2
THE NEXT ERA OF DRONES WILL BE DEFINED BY ‘SWARMS’
[ …]
Drones are becoming smaller, cheaper to make, can zoom around on their own, and gather
in groups of hundreds, even thousands, to fly like a flock of birds.
They’re called swarms – get enough of them together, and they could save your life, or they
could be a deadly collaborative force on the battlefield.
[ …]
Plus there is no leader (1) or commander in a swarm; the swarm is a self-organising system
in which allows drones to fly together without colliding. And only one operator (2) is needed
to control the whole swarm.
Swarms are tough. One missile can bring down an aircraft, but a swarm can lose dozens of
members and keep going. Air defences with a limited (3) supply (4) of missiles can be
overwhelmed by enough opponents.
But drones will soon be swarming in many other situations too, from rock concerts to
barnyards. In fact, you probably already have seen swarms of drones in everyday life.
Chinese company eHang claimed the record for the biggest swarm, in a spectacular New
Year show in which 1,000 drones formed a map of China and the Chinese character for
'blessings' (5).
Drone swarms may even have a place on the farm. They can spot plant disease and help
manage water use, or spray pesticides and herbicides only in the exact spot needed, all
working cooperatively to cover the area and fill in gaps.
So, what does the future hold for swarming (6) drones? Swarming drone technology is still
very much in their infancy. But it’s evolving fast. In fact, they could one day live alongside us.

Gabarito comentado
Tema central:
A questão aborda interpretação de texto em Inglês, focando na compreensão de ideias principais, inferências e identificação de informações incorretas sobre o avanço tecnológico de drones em "swarms" (enxames).
Comentário e Justificativa do Gabarito:
A alternativa B está incorreta, pois ela afirma: “The swarm is a system that is fully tested and can be used in all different fields immediately.” Entretanto, segundo o texto, a tecnologia de enxames ainda ‘está em sua infância’ (“swarming drone technology is still very much in their infancy”), ou seja, não está completamente desenvolvida ou pronta para uso imediato em todas as áreas. A leitura atenta desta parte do texto é essencial para perceber a incoerência entre a alternativa e o conteúdo.
Estratégia de interpretação:
Uma técnica importante é buscar por expressões no texto que indiquem etapa de desenvolvimento ou limitação (infancy, evolving fast), confrontando-as com termos absolutos (“fully tested”, “immediately”, “in all different fields”). Fique atento: alternativas que generalizam ou absolutizam frequentemente trazem erros, configurando verdadeiras “pegadinhas”.
Análise das alternativas:
A) Correta – O texto confirma que “only one operator is needed to control the whole swarm”, justificando a afirmação.
B) Incorreta (Gabarito) – Contradiz a realidade apresentada sobre o estágio atual da tecnologia.
C) Correta – O texto sugere o potencial de uso em batalhas futuras (“could be a deadly collaborative force on the battlefield”).
D) Correta – Todas as características citadas (“smaller, cheaper, autonomous, fly in groups”) estão presentes no texto.
E) Correta – O texto relata usos em fazendas e manejo agrícola (“They can spot plant disease and help manage water use…”).
Dica de prova:
Fique atento a palavras como “fully”, “immediately” ou “all”, que criam afirmações absolutas. Muitos textos, especialmente tecnológicos, enfatizam o estágio inicial ou as limitações das inovações.
Resumo: A alternativa B é a incorreta, pois não condiz com a informação textual sobre a maturidade dos enxames de drones. Saber comparar ideias do texto com as alternativas é essencial para obter êxito em questões de interpretação de texto.
