According to Text , what is one of the findings of another study on the same issue?
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
Resposta correta: C — People will wash their hands if they are being watched.
Tema central: interpretação de texto — identificar informação explícita em um trecho específico. Aqui é preciso reconhecer qual afirmação pertence a estudos “outros” mencionados no texto (marca discursiva: Other hand-washing research has found...).
Resumo teórico rápido: em reading comprehension, procure por conectivos que introduzem novas fontes ou resultados (ex.: "other", "however", "in contrast"). Esses sinais indicam que a informação seguinte refere-se a estudos diferentes do principal. Faça scan no parágrafo para localizar a lista de achados e escolha a opção que reproduz literalmente (ou porparáfrase fiel) um desses achados.
Justificativa da alternativa C: o trecho diz explicitamente que outras pesquisas encontraram que “people will wash their hands if they're being watched.” A alternativa C é, portanto, uma repetição fiel dessa ideia — trata-se de informação explícita no texto e corresponde exatamente ao enunciado solicitado.
Análise das alternativas incorretas:
A — "Antibacterial soap is worse than the regular kind." O texto afirma que antibacterial soap "isn't much better than the regular kind" (não é muito melhor), ou seja, não há afirmação de que seja pior. A alternativa altera o sentido (troca “não muito melhor” por “pior”) — pegadinha semântica.
B — "People are more likely to wash their hands if there is a sign." Esse resultado aparece no próprio estudo principal (lista de “tidbits”), não em “other research”. A pergunta pede um achado de outra pesquisa, portanto B refere-se ao estudo principal e é incorreta no contexto solicitado.
D — "People are less likely to wash their hands if the sink is not clean." Semelhante à B: o texto menciona que, no estudo principal, pessoas lavavam menos as mãos se a pia estava suja. Mas a pergunta pede um achado de outra pesquisa; logo D também não responde corretamente ao que foi solicitado.
Estratégias úteis para provas:
- Localize conectivos (ex.: "Other", "however") que mudam a referência dos dados. - Prefira respostas que reproduzam o sentido literal do texto em vez de reinterpretações que invertem ou exageram. - Cuidado com sinônimos que mudam o escopo (ex.: "study" principal × "other studies").
Fonte útil: CDC — recomenda lavar as mãos com água e sabão por pelo menos 20 segundos (ver orientações do CDC sobre handwashing).
