A que se refere o pronome it, na oração it reduces carbon missions by between 65% and 80% ?
Sustainable flight
TAM was the first airline in South America to carry out an experimental flight using biofuel on November 22, 2010. Produced from the oil of 100% domestic nettlespurge, known in Portuguese as pinhão-manso, it reduces carbon emissions by between 65% and 80% compared with petroleum-derived kerosene, according to research. Besides, the plant does not threatens the food chain, as it is not edible for humans nor animals. “Compared with other biofuels, the fuel from this plant is very promising for the Brazilian scenario,” says Paulus Figueiredo, TAM’s fuel manager. The next step in the project is to implement a farming unit, in reduced scale, at TAM’s Technological Center in São Carlos (SP), exclusively to conduct studies and make better cultivation techniques viable. “The objective is to carry out studies concerning technical and economic viability to build a biofuel Brazilian platform based on nettlespurge,” explains TAM’s CEO, Líbano Barroso. The experimental flight was a joint effort between TAM, Airbus, CFM International (joint venture between U.S.’s GE and the French Safran Group) and Air BP. The trip was authorized by Brazil’s National Civil Aviation Agency (ANAC) and by the European Aviation Safety Agency (EASA).

Gabarito comentado
Gabarito: A
Fundamento decisivo: O critério decisivo é a coesão referencial por compatibilidade semântica: no trecho "Produced from the oil of 100% domestic nettlespurge, known in Portuguese as pinhão-manso, it reduces carbon emissions by between 65% and 80% compared with petroleum-derived kerosene", o pronome "it" retoma o referente que pode exercer a ação de "reduces carbon emissions" e integrar a comparação com "petroleum-derived kerosene". Esse referente é o biofuel/fuel produzido a partir da planta, o que sustenta o gabarito A.
- Não escolha o antecedente pelo critério de proximidade; teste qual termo mantém sentido com o verbo da oração.
- Quando houver estrutura como "produced from", separe a matéria-prima do produto antes de identificar o referente pronominal.
- Em comparações com "compared with", verifique quais elementos pertencem à mesma categoria; aqui, a comparação é entre combustíveis.
