TEXT I

Is peanut butter a good source of protein? Nutrition experts explain.

[1] Protein is the macronutrient du jour. Discussions about nutrition online as of late are all about making sure you're consuming enough protein every day.

[2] The Recommended Dietary Allowance (RDA) for protein is currently 0.36 grams of protein per pound, according to Harvard Health, or about 54 grams daily for a person who weighs 150 pounds.

[3] But diet experts are increasingly pushing for consuming higher amounts of protein: upwards of 60 to 90 grams daily. Registered dietitian Jamie Nadeau previously told USA TODAY that she recommends getting "at least 20 grams of protein per meal for satiety," though she notes everyone has different needs.

[4] To what extent can peanut butter help you reach those goals? Nutrition experts explain.

[5] A two-tablespoon serving of peanut butter contains about 7 grams of protein, according to the U.S. Department of Agriculture's (USDA) food database.

[6] That doesn't mean you shouldn't eat peanut butter – experts say it just means peanut butter is meant to be a small part of more well-rounded meals. Thomason suggests pairing a serving of peanut butter with a carb, protein and a fruit or vegetable. Some favorite combos include peanut butter and an apple, peanut butter and banana toast and a smoothie or oatmeal with peanut butter.

[7] "Those things are going to help you balance it out and not feel like it's easy to overeat," she says.

[8] To hit that recommended 20-gram goal, you'd have to eat about 6 tablespoons – nearly three servings of peanut butter – which amounts to nearly 600 calories. While experts say eating more than the serving size isn't harmful, per se, there are much easier (and less calorie-dense) food options to get more protein.

(Adapted from https://www.usatoday.com)

The pronoun "it" in the sentence "Those things are going to help you balance it out and not feel like it's easy to overeat, [...]" (paragraph 7) refers to:

Resolução comentada

O pronome 'it' retoma 'peanut butter'.

No parágrafo 7, 'Those things' são os acompanhamentos citados (carboidrato, proteína, fruta ou vegetais). Eles ajudam a equilibrar a pasta de amendoim, que é o tema central do trecho. O 'it' retoma, portanto, 'peanut butter'.

Análise das alternativas

A, B, C e D) Maçã, torrada de banana, smoothie e aveia são exemplos de combinações. Eles fazem parte do que 'Those things' designa e não são aquilo que se equilibra. E) Correta.

According to text I:

Selecione uma alternativa A) Harvard Health believes consumers' daily intake of protein should be increased. B) Peanut butter should be our first choice of protein, according to nutrition experts. C) Jamie Nadeau recommends adding other sources of protein to peanut butter. D) There are people who do not need to consume at least 20 grams of protein per meal. E) One serving of peanut butter is one tablespoon and contains nearly 100 calories.

Resolução comentada

Segundo o texto, as necessidades de proteína variam de pessoa para pessoa.

No parágrafo 3, a nutricionista recomenda pelo menos 20 g de proteína por refeição, mas ressalva que 'everyone has different needs'. Logo, há pessoas que não precisam consumir esse mínimo, o que torna D correta.

Análise das alternativas

A) A Harvard Health apenas informa a RDA. Quem defende quantidades maiores são 'diet experts'. B) O texto diz que a pasta de amendoim deve ser parte pequena de refeições variadas e que há opções melhores de proteína. C) Nadeau não fala em combinar a pasta com outras fontes de proteína. Quem sugere combinações é Thomason. E) Uma porção são duas colheres de sopa, não uma, e o texto dá cerca de 200 calorias por porção (600 kcal para quase três porções).

Chinese divers surrounded by sharks

Jan 03, 2025

[1] Nine Chinese individuals, including seven tourists and two diving instructors, went missing while diving in Palau on December 26.

[2] Experienced diving instructor Liu Xin and another diving guide took seven Chinese tourists to dive on December 26 around 9:30 am. As the dive was coming to an end, Liu sent a signal to the surface. Typically, after seeing the signal, the captain would slowly maneuver the boat to follow the divers, allowing them to board once they floated off. __________, when they surfaced, they could not locate the boat.

[3] They could only float in the sea for nearly three hours, believing that someone would come to rescue them, but the ocean current changed direction, and they were swept by currents into an area between two islands. At that point, a new threat emerged. The underwater terrain shifted, and the most physically fit diver among the nine felt as if he had stepped on something. Liu looked down and noticed that a bull shark was circling around his feet, along with six other sharks nearby.

[4] Liu swiftly assembled everyone to make themselves appear larger as most wild animals typically target creatures that are smaller and tend to avoid approaching larger groups. Fortunately, with Liu and the entire team huddled together, the sharks refrained from acting aggressively, and they avoided any danger.

[5] By evening, they had gone nearly 11 hours without food. To conserve their energy, they used their diving masks to collect rainwater and drank it to stay hydrated. After spending too much time in the water, they started to feel cold, so they used their buoyancy devices to hold each other to stay together and preserve warmth. And, to prevent falling asleep and risking hypothermia, they took turns calling out their numbers every 30 minutes to stay alert.

[6] After drifting in the water for about 27 hours, a rescue boat located the nine individuals.

[7] "All nine Chinese citizens who went missing while diving in Palau have been rescued and are reported to be in stable condition", the Chinese Embassy in the Federated States of Micronesia said on Friday.

[8] Liu said that the key reasons for their safe return included the selfless assistance from fellow travelers, the favorable ocean currents that kept them in proximity to their initial location, and, most importantly, the excellent physical condition and positive attitude of the group. "Throughout those 20-plus hours, we maintained a light-hearted atmosphere, chatting and laughing without any complaints," Liu said.

(Adapted from https://www.globaltimes.cn)

The word "selfless" (paragraph 8) means:

Resolução comentada

Sentido de 'selfless' no texto: generoso, altruísta.

'Selfless' significa desprendido, que pensa nos outros antes de si. No parágrafo 8, 'selfless assistance from fellow travelers' é a ajuda generosa dos companheiros de viagem. Por isso 'generous' é o sinônimo mais próximo.

Análise das alternativas

B) 'quick' significa rápido. C) 'recent' significa recente. D) 'selfish' é egoísta, o antônimo. E) 'unexpected' significa inesperado.

Não se usa "will" na oração com if; E é a incorreta.

Em condicionais, a oração com "if" não leva "will" para o futuro. Na alternativa E, "if anonymity will be outlawed" está incorreto, e o certo seria "is outlawed". As demais seguem as estruturas condicionais corretas.

Análise das alternativas

A) Segundo condicional (o uso de "was" é aceito na língua informal). B) Segundo condicional bem formado. C) Primeiro condicional correto. D) Condicional zero/primeiro correto.

Discurso indireto: will → would; tomorrow → the following day.

Ao reportar "I will travel tomorrow" com verbo introdutório no passado, "will" vira "would" e "tomorrow" vira "the following day". A opção E faz isso corretamente: "Carol said she would travel the following day".

Análise das alternativas

A) "Said me" é incorreto e o tempo está errado. B) "Told that" está sem objeto e muda o sujeito. C) "Says" e "I will" não foram ajustados. D) "Will" e "the day before" não correspondem a "tomorrow".

Which question completes the dialogue below correctly?

Richard: She's won a gold medal.
Paul: _____

Selecione uma alternativa A) Neither am I. B) So have I. C) Neither is she. D) So am I. E) Neither have I.

Resolução comentada

Concordância afirmativa com present perfect: So have I.

A frase de Richard está no present perfect ("has won"). Para concordar com uma afirmação, usa-se "So + auxiliar + sujeito", e Paul fala de si mesmo, então "So have I".

Análise das alternativas

A, C e E usam "Neither", que serve para concordar com frases negativas. D usa "am", mas o auxiliar deveria ser "have".
