    Leia o soneto de Luís de Camões para responder à questões.



    Quem diz que Amor é falso ou enganoso,

    ligeiro, ingrato, vão, desconhecido,

    sem falta1 lhe terá bem merecido

    que lhe seja cruel ou rigoroso.


    Amor é brando2, é doce e é piadoso3.

    Quem o contrário diz não seja crido;

    seja por cego e apaixonado tido,

    e aos homens, e inda4 aos deuses, odioso.


    Se males faz Amor, em mim se veem;

    em mim mostrando todo o seu rigor,

    ao mundo quis mostrar quanto podia.


    Mas todas suas iras são de amor;

    todos estes seus males são um bem,

    que eu por todo outro bem não trocaria.



    (Luís de Camões. Sonetos: antologia comentada, 2012.)



    1 sem falta: sem dúvida.

    2 brando: manso, meigo.

    3 piadoso: piedoso.

    4 inda: ainda.

    “Se males faz Amor, em mim se veem;” (3ª estrofe)

        In my research recently published in an open access journal, I used a popular language model, GPT-4 by OpenAI, to create simple summaries of scientific papers. These summaries generated by artificial intelligence (AI) used simpler language and more common words, like “job” instead of “occupation”, than summaries written by the researchers who had done the work.


        In one experiment, I found that readers of the AI-generated summaries had a better understanding of the science than readers of the human-written summaries. A second experiment investigated what effects the simpler summaries might have on people’s perceptions of the scientists who performed the research. In this experiment, participants rated the scientists whose work was described in the simpler texts as more credible than the scientists whose work was described in the more complex texts.


        Have you ever read about a scientific discovery and felt like it was written in a foreign language? New scientific information is probably hard to understand — especially if you try to read a science article in a research journal. In an era where understanding science is crucial for informed decision--making, the abilities to comprehend and communicate complex ideas are more important than ever. Trust in science has been declining for years, and one contributing factor may be the challenge of understanding scientific jargon.


        As AI continues to evolve, its role in science communication may expand, especially if using generative AI becomes more commonplace. Simple science descriptions are preferable to and more beneficial than complex ones, and AI tools can help. But scientists could also achieve the same goals by working harder to minimize jargon and communicate clearly — no AI necessary.

    Literatura

    A Literatura não está dissociada do meio. Os fragmentos abaixo descrevem três autores representantes do Modernismo/Pós-Modernismo da literatura brasileira e o contexto no qual estavam inseridos.

    − “Em 1936, ..................................... foi preso por atividades consideradas subversivas, mas libertado no ano seguinte. Essas experiências pessoais foram retratadas em seu livro Memórias do cárcere. É tido hoje como o autor que levou ao limite o clima de tensão presente nas relações homem/meio natural e homem/meio social, tensão essa geradora de um relacionamento violento, capaz de moldar personalidades e de transfigurar o que os homens têm de bom. A luta pela sobrevivência, portanto, parece ser o grande ponto de contato entre todos os personagens; a lei maior é a da selva."
    − “Publicando seu primeiro livro em 1946, um ano após a queda de Getúlio Vargas e o início das produções da chamada Geração de 45, ..................................... apontaria novos rumos para a literatura brasileira. Os contos Sagarana abririam uma nova perspectiva para o regionalismo. A princípio, percebe-se uma revalorização da linguagem; depois, a universalização do regional."
    − “Com o AI-5 e os ataques de grupos de extrema-direita, desmantela-se o teatro de resistência; autores importantes, como Augusto Boal e José Celso, vão para o exílio; outros, como ....................................., continuam a produzir textos apesar da repressão. Sua obra O berço do herói é censurada, e mesmo uma década depois, já com outro nome, Roque Santeiro, numa adaptação para a televisão, ainda é vetada no dia da estreia." Adap. TERRA, Ernani, NICOLA, José. Gramática, literatura e redação para o 2º grau. São Paulo: Scipione, 1997.

    Americans May Add Five Times More Plastic to the Oceans Than Thought

    The United States is using more
    plastic than ever, and waste exported for
    recycling is often mishandled, according
    to a new study.
    The United States contribution
    to coastal plastic pollution worldwide is
    significantly larger than previously
    thought, possibly by as much as five
    times, according to a study published
    Friday. The research, published in Science
    Advances, is the sequel to a 2015 paper
    by the same authors. Two factors
    contributed to the sharp increase:
    Americans are using more plastic than
    ever and the current study included
    pollution generated by United States
    exports of plastic waste, while the earlier
    one did not.
    The United States, which does
    not have sufficient infrastructure to
    handle its recycling demands at home,
    exports about half of its recyclable waste.
    Of the total exported, about 88 percent
    ends up in countries considered to have
    inadequate waste management.
    “When you consider how much
    of our plastic waste isn’t actually
    recyclable because it is low-value,
    contaminated or difficult to process, it’s
    not surprising that a lot of it ends up
    polluting the environment,” said the
    study’s lead author, Kara Lavender Law,
    research professor of oceanography at
    Sea Education Association, in a
    statement.
    The study estimates that in
    2016, the United States contributed
    between 1.1 and 2.2 million metric tons of
    plastic waste to the oceans through a
    combination of littering, dumping and 
    mismanaged exports. At a minimum,
    that’s almost double the total estimated
    waste in the team’s previous study. At the
    high end, it would be a fivefold increase
    over the earlier estimate.
    Nicholas Mallos, a senior
    director at the Ocean Conservancy and an
    author of the study, said the upper
    estimate would be equal to a pile of
    plastic covering the area of the White
    House Lawn and reaching as high as the
    Empire State Building.
    The ranges are wide partly
    because “there’s no real standard for
    being able to provide good quality data on
    collection and disposal of waste in
    general,” said Ted Siegler, a resource
    economist at DSM Environmental
    Solutions, a consulting firm, and an
    author of the study. Mr. Siegler said the
    researchers had evaluated waste-disposal
    practices in countries around the world
    and used their “best professional
    judgment” to determine the lowest and
    highest amounts of plastic waste likely to
    escape into the environment. They settled
    on a range of 25 percent to 75 percent.
    Tony Walker, an associate
    professor at the Dalhousie University
    School for Resource and Environmental
    Studies in Halifax, Nova Scotia, said that
    analyzing waste data can amount to a
    “data minefield” because there are no
    data standards across municipalities.
    Moreover, once plastic waste is shipped
    overseas, he said, data is often not
    recorded at all.
    Nonetheless, Dr. Walker, who
    was not involved in the study, said it
    could offer a more accurate accounting of
    plastic pollution than the previous study,
    which likely underestimated the United
    States’ contribution. “They’ve put their
    best estimate, as accurate as they can be
    with this data,” he said, and used ranges,
    which underscores that the figures are
    estimates.
    Of the plastics that go into the
    United States recycling system, about 9
    percent of the country’s total plastic
    waste, there is no guarantee that they’ll
    be remade into new consumer goods. New
    plastic is so inexpensive to manufacture
    that only certain expensive, high-grade
    plastics are profitable to recycle within the
    United States, which is why roughly half
    of the country’s plastic waste was shipped
    abroad in 2016, the most recent year for
    which data is available.
    Since 2016, however, the
    recycling landscape has changed. China
    and many countries in Southeast Asia
    have stopped accepting plastic waste
    imports. And lower oil prices have further
    reduced the market for recycled plastic.
    “What the new study really underscores is
    we have to get a handle on source
    reduction at home,” Mr. Mallos said. “That
    starts with eliminating unnecessary and
    problematic single-use plastics.”

    plastic is so inexpensive to manufacture
    that only certain expensive, high-grade

    Americans May Add Five Times More Plastic to the Oceans Than Thought

    The United States is using more
    plastic than ever, and waste exported for
    recycling is often mishandled, according
    to a new study.
    The United States contribution
    to coastal plastic pollution worldwide is
    significantly larger than previously
    thought, possibly by as much as five
    times, according to a study published
    Friday. The research, published in Science
    Advances, is the sequel to a 2015 paper
    by the same authors. Two factors
    contributed to the sharp increase:
    Americans are using more plastic than
    ever and the current study included
    pollution generated by United States
    exports of plastic waste, while the earlier
    one did not.
    The United States, which does
    not have sufficient infrastructure to
    handle its recycling demands at home,
    exports about half of its recyclable waste.
    Of the total exported, about 88 percent
    ends up in countries considered to have
    inadequate waste management.
    “When you consider how much
    of our plastic waste isn’t actually
    recyclable because it is low-value,
    contaminated or difficult to process, it’s
    not surprising that a lot of it ends up
    polluting the environment,” said the
    study’s lead author, Kara Lavender Law,
    research professor of oceanography at
    Sea Education Association, in a
    statement.
    The study estimates that in
    2016, the United States contributed
    between 1.1 and 2.2 million metric tons of
    plastic waste to the oceans through a
    combination of littering, dumping and 
    mismanaged exports. At a minimum,
    that’s almost double the total estimated
    waste in the team’s previous study. At the
    high end, it would be a fivefold increase
    over the earlier estimate.
    Nicholas Mallos, a senior
    director at the Ocean Conservancy and an
    author of the study, said the upper
    estimate would be equal to a pile of
    plastic covering the area of the White
    House Lawn and reaching as high as the
    Empire State Building.
    The ranges are wide partly
    because “there’s no real standard for
    being able to provide good quality data on
    collection and disposal of waste in
    general,” said Ted Siegler, a resource
    economist at DSM Environmental
    Solutions, a consulting firm, and an
    author of the study. Mr. Siegler said the

    Advances, is the sequel to a 2015 paper
    by the same authors. Two factors
    contributed to the sharp increase:
    Americans are using more plastic than
    ever and the current study included
    pollution generated by United States
    exports of plastic waste, while the earlier
    one did not.
    The United States, which does
    not have sufficient infrastructure to
    handle its recycling demands at home,
    exports about half of its recyclable waste.
    Of the total exported, about 88 percent
    ends up in countries considered to have
    inadequate waste management.
    “When you consider how much
    of our plastic waste isn’t actually
    recyclable because it is low-value,
    contaminated or difficult to process, it’s
    not surprising that a lot of it ends up
    polluting the environment,” said the
    study’s lead author, Kara Lavender Law,
    research professor of oceanography at
    Sea Education Association, in a
    statement.
    The study estimates that in
    2016, the United States contributed
    between 1.1 and 2.2 million metric tons of
    plastic waste to the oceans through a
    combination of littering, dumping and 
    mismanaged exports. At a minimum,
    that’s almost double the total estimated
    waste in the team’s previous study. At the
    high end, it would be a fivefold increase
    over the earlier estimate.
    Nicholas Mallos, a senior
    director at the Ocean Conservancy and an
    author of the study, said the upper
    estimate would be equal to a pile of
    plastic covering the area of the White
    House Lawn and reaching as high as the
    Empire State Building.
    The ranges are wide partly
    because “there’s no real standard for
    being able to provide good quality data on
    collection and disposal of waste in
    general,” said Ted Siegler, a resource
    economist at DSM Environmental
    Solutions, a consulting firm, and an
    author of the study. Mr. Siegler said the
    researchers had evaluated waste-disposal
    practices in countries around the world
    and used their “best professional
    judgment” to determine the lowest and
    highest amounts of plastic waste likely to
    escape into the environment. They settled
    on a range of 25 percent to 75 percent.
    Tony Walker, an associate
    professor at the Dalhousie University
    School for Resource and Environmental
    Studies in Halifax, Nova Scotia, said that
    analyzing waste data can amount to a
    “data minefield” because there are no
    data standards across municipalities.
    Moreover, once plastic waste is shipped
    overseas, he said, data is often not
    recorded at all.
    Nonetheless, Dr. Walker, who
    was not involved in the study, said it
    could offer a more accurate accounting of
    plastic pollution than the previous study,
    which likely underestimated the United
    States’ contribution. “They’ve put their
    best estimate, as accurate as they can be
    with this data,” he said, and used ranges,
    which underscores that the figures are
    estimates.
    Of the plastics that go into the
    United States recycling system, about 9
    percent of the country’s total plastic
    waste, there is no guarantee that they’ll
    be remade into new consumer goods. New
    plastic is so inexpensive to manufacture
    that only certain expensive, high-grade
    plastics are profitable to recycle within the
    United States, which is why roughly half
    of the country’s plastic waste was shipped
    abroad in 2016, the most recent year for
    which data is available.
    Since 2016, however, the
    recycling landscape has changed. China
    and many countries in Southeast Asia
    have stopped accepting plastic waste
    imports. And lower oil prices have further
    reduced the market for recycled plastic.
    “What the new study really underscores is
    we have to get a handle on source
    reduction at home,” Mr. Mallos said. “That
    starts with eliminating unnecessary and
    problematic single-use plastics.”

    Americans May Add Five Times More Plastic to the Oceans Than Thought

    The United States is using more
    plastic than ever, and waste exported for
    recycling is often mishandled, according
    to a new study.
    The United States contribution
    to coastal plastic pollution worldwide is
