Leia o texto para responder às questões de 24 a 30. When does the brain work best? The peak times and ages for learning [IMAGEM] What’s your ideal time of the day for brain performance? Surprisingly, the answer to this isn’t as simple as being a morning or a night person. New research has shown that certain times of the day are best for completing specific tasks, and listening to your body’s natural clock may help you to accomplish more in 24 hours. Science suggests that the best time for our natural peak productivity is late morning. Our body temperatures start to rise just before we wake up in the morning and continue to increase through midday, Steve Kay, a professor of molecular and computational biology at the University of Southern California told The Wall Street Journal. This gradual increase in body temperature means that our working memory, alertness, and concentration also gradually improve, peaking at about mid morning. Our alertness tends to dip after this point, but one study suggested that midday fatigue may actually boost our creative abilities. For a 2011 study, 428 students were asked to solve a series of two types of problems, requiring either analytical or novel thinking. Results showed that their performance on the second type was best at non-peak times of day when they were tired. As for the age where our brains are at peak condition, science has long held that fluid intelligence, or the ability to think quickly and recall information, peaks at around age

1. A) body temperature gets higher at this time of the day.
2. B) specific tasks stimulate the brain.
3. C) most people wake up quite early.
4. D) it’s easier to solve problems in the morning than at midday.
5. E) human natural rhythm reaches a steady level.

✅ Resposta correta: alternativa A

Resolução passo a passo

1. O enunciado pergunta por que o texto considera o final da manhã (late morning) o melhor momento para a produtividade natural. Para responder, procure no texto a justificativa dada pelo professor Steve Kay. Passo 2: O texto afirma que a temperatura corporal começa a subir pouco antes de acordarmos e continua a aumentar até o meio-dia. Passo 3: Esse aumento gradual da temperatura faz com que a memória de trabalho, o estado de alerta e a concentração também melhorem gradualmente, atingindo o pico por volta de meio da manhã. Passo 4: Portanto, a alternativa correta é a A, pois a temperatura corporal fica mais alta nesse horário, o que explica o pico de desempenho. Passo 5: Por que as outras estão erradas: B fala de tarefas específicas estimulando o cérebro, mas o texto apenas diz que certos horários são melhores para certas tarefas, sem explicar a causa. C menciona que a maioria das pessoas acorda cedo, algo que não aparece como explicação no texto. D compara a facilidade de resolver problemas de manhã e ao meio-dia, mas o texto diz que o desempenho em problemas de pensamento novo foi melhor em horários de baixa energia e cansaço. E sugere que o ritmo natural se mantém em um nível constante, quando o texto descreve justamente um ritmo que varia ao longo do dia.

💡 Dica: Leia atentamente o texto para identificar a informação correta.
