What is the most adequate title for Text ?
Text
"Many people do not wash their hands when the behavior in which they engage would warrant it," begins a recent study from
Michigan State University, and I'm sorry to say it only gets grosser from there. Researchers sneakily observed 3,749 people
in public restrooms and found that nearly all of them—95 percent—didn't wash their hands long enough to kill germs.
Even scarier, 15 percent of men and 7 percent of women did not wash their hands at all. When they did bother to turn on a
faucet, half of men and 22 percent of women neglected to use soap! (Or, as the researchers describe it: They "attempted to
wash their hands," but failed.)
The CDC says you need to wash your hands—with soap!—for at least 20 seconds in order to kill disease-causing germs.
Alas, the people in this study only washed their hands for an average of 6 seconds (...)
This extensive study founds lots of other interesting tidbits about hand-washing habits. Here are a few:
• People were more likely to wash their hands in the morning
• People were less likely to wash their hands if the sink was dirty
• People were more likely to wash their hands if there was sign to remind them
Other hand-washing research has found that college students are disgusting, people will wash their hands if they're being
watched, and antibacterial soap isn't much better than the regular kind.
The study appears in the Journal of Environmental Health.

Gabarito comentado
Alternativa correta: B - Only 5 percent of people wash their hands correctly.
Tema central: interpretar a ideia principal de um texto jornalístico-científico e escolher o título que a resume melhor. Aqui é necessário identificar qual informação constitui o núcleo do texto — no caso, a baixa proporção de pessoas que lavam as mãos pelo tempo e com o cuidado recomendados.
Resumo teórico e estratégia: para escolher título adequado, procure (1) a ideia mais repetida ou enfatizada; (2) dados numéricos centrais; (3) instruções ou recomendações citadas (ex.: CDC recomenda 20 segundos). Títulos devem ser concisos, precisos e refletir o foco do texto. Fonte de respaldo: CDC — recomenda lavar as mãos por pelo menos 20 segundos para eliminar germes.
Por que B está certa: o texto enfatiza estatística-chave: apenas uma pequena fração das pessoas lava as mãos corretamente (o estudo aponta que 95% não lavam tempo suficiente), portanto ≈5% lavam corretamente. O título B reproduz com precisão esse dado central e resume a mensagem principal de forma direta.
Por que as outras alternativas estão erradas:
A - People in public restrooms do not bathe properly. — incorreta: “bathe” é exagero e fora de contexto; o texto trata de lavar as mãos, não do banho corporal. Além disso é generalizadora e imprecisa.
C - Men are more inattentive when washing hands. — incorreta: embora o texto apresente diferenças por gênero (percentuais diferentes), esse detalhe é secundário. O foco principal é a baixa taxa geral de lavagem correta, não apenas comportamento masculino.
D - Faucets in restrooms are not adequate for washing hands correctly. — incorreta: o texto menciona que pia suja desestimula a lavagem, mas não afirma que as torneiras são inadequadas. Essa alternativa insere uma conclusão não sustentada pelo texto.
Dica prática para provas: priorize títulos que reflitam a tese central e dados estatísticos destacados; risque opções que ampliem, distorçam ou especulem além do texto. Use números e palavras-chave do parágrafo inicial e conclusivo como pistas.
