According to text B, after adopting SODIS:
TEXT B
High Marks for Clean Water
Retrieve a discarded water bottle. Tear off the label and fill
it with any water that’s not too murky from a creek, standpipe or a
puddle. Place the bottle on a piece of metal in full sun. In six hours
the UVA radiation will kill viruses, bacteria and parasites in the water,
making it safe to drink. SODIS, the acronym for this Swiss - pioneered water -
disinfection program, is now being used all over the world to provide
drinking water for some four million people. “It’s simple, it’s free, and
it’s effective,” says Ibelatha Mhelela, principal of the Ndolela Primary
School in Tanzania. In 2006 her school started using SODIS to
disinfect its contaminated tap water, placing bottles on the building’s
corrugated metal roof. The result? Absenteeism due to diarrhea has
dropped considerably, and examination scores soared. “Before we
started SODIS, only ten to fifteen percent of the children passed the
national sixth grade exams,” says Mhelela, “Now ninety to ninety -
five percent of the students pass.”

Gabarito comentado
A
Andréia Farias Monitor com apoio de IA
Gabarito: D
Fundamento decisivo: O enunciado pede a situação after adopting SODIS, e o trecho decisivo contrapõe before e now: “Before we started SODIS, only ten to fifteen percent of the children passed... Now ninety to ninety-five percent of the students pass.” Como o dado posterior é 90% a 95%, conclui-se que passou a maioria dos estudantes, o que sustenta o gabarito D.
Tema central: contraste temporal e percentual
Análise das alternativas
A
Errada
Incorreta. O percentual de 15% pertence ao período anterior ao SODIS, conforme o trecho “Before we started SODIS, only ten to fifteen percent...”. A questão exige o cenário posterior à adoção do programa.
B
Errada
Incorreta. Three quarters corresponde a 75%, mas o texto informa, depois do SODIS, uma faixa de 90% a 95%. Há incompatibilidade numérica com o dado expresso.
C
Errada
Incorreta. O percentual de 10% também está no trecho referente ao período anterior ao SODIS. O erro é ignorar o marcador temporal pedido no enunciado: after adopting SODIS.
D
Certa
A alternativa D está correta porque o texto afirma expressamente, no momento posterior à adoção do SODIS, que “Now ninety to ninety-five percent of the students pass.” Essa faixa de 90% a 95% é superior a 50%, portanto sustenta tecnicamente a afirmação de que a maioria dos estudantes passou no exame nacional da sexta série.
E
Errada
Incorreta. Less than half significa menos de 50%, o que contradiz diretamente a informação textual de que, após o SODIS, 90% a 95% dos estudantes passaram.
Pegadinha da questão
A banca explorou a confusão entre os percentuais de antes da adoção do SODIS (10% a 15%) e os percentuais de depois (90% a 95%), além de substituir o número exato por uma formulação geral correta: majority.
Dica para questões semelhantes
- Localize primeiro os marcadores temporais do texto, como before, after e now, para não misturar momentos diferentes.
- Quando a alternativa resume um dado numérico com uma expressão geral, verifique se ela é logicamente compatível com o percentual informado.
- Elimine alternativas com números específicos que não coincidam com a faixa expressa no texto, mesmo que pareçam plausíveis.
