TEXT A Since Barack Obama was elected in 2008, the price of solar energy has fallen 78 percent, and the cost of wind energy has also fallen by 58 percent, thanks largely to technological advancements and economies of scale. In isolation, these numbers are not impressive. But what makes the difference is that the global economy grew by 3 percent in 2014 while world emissions remained flat. Cheaper alternative energy is the best hope the world has left. People are not willing to fundamentally change their lives for problems far off in the future, even ones as potentially catastrophic as climate change. To avoid the worst effects of climate change, alternative energies need to become as cheap and reliable as their carbon-emitting counterparts, and quickly. TEXTB The thoroughly modern phenomenon of cybercrime and economic espionage is estimated to cost the world more than $445 billion every year. And while it hasn't happened yet, the fear that cyberattacks can spill over and trigger real-world conflicts remains an ongoing concern. A decade ago, the Pentagon had a stockpile of fewer than 50 drones; today it has an arsenal of about 7,000. The Pentagon estimates that China will build nearly 42,000 drones by 2023. Others will follow suit. Technology has given terrorist groups like ISIS an unparalleled platform to spread their messages of hate. The knowledge needed to build bombs in the comfort of your own home is now just a few short clicks away. Technology is capable of empowering every single individual in the world, even the worst of us. Disponível em: . Acesso em: 16 maio 2021.

Across the board, suicide rates among young Americans have risen; from 2007 to 2018, suicide rates for Americans ages 10 to 24 rose by 57%, and the increase was particularly significant among young girls, contributing to a narrowing of the persistent suicide gender gap. Rates plateaued from 2018 to 2019—the most recent year with available federal data—but they stood far higher than those of decades past. A multinational study published in the Lancet Psychiatry in April found that U.S. suicide rates actually decreased somewhat during the early months of the pandemic, compared to the year before it—but given spiking anxiety and depression rates during the pandemic, which studies suggest took a particularly harsh toll on young people, there’s good reason for continuing concern. Girls of color are increasingly accounting for this trend. According to one 2019 Pediatrics study, the number of white children attempting suicide in the U.S. decreased from 1991 to 2017, while the number of Black children attempting suicide went up. “Black youths are two times more likely to die by suicide compared to their white counterparts,” says Arielle Sheftall. Now, she says, “we're trying to figure this out.” There's rarely a single thing that drives someone to attempt suicide, and similarly there are many factors—from bullying to stigma to childhood trauma and racism—but no one cause that could help to explain the increase in suicides among Black youth.

An astonishing 40% of bees die every year as a result of disease, pesticides and climate change — in part because busy commercial beekeepers miss warning signs. That's where Beewise, an artificial-intelligence-powered hive, comes in. Using precision robotics, computer vision and Al, a Beehome — which costs $15 a month and might host 2 million bees — monitors the insects 24/7. When a hive is exposed to, say, parasites or experiences irregular temperatures, its internal systems respond immediately by applying pesticides, for example. Use of the smart technology can double pollination capacity and honey production, while decreasing colonies’ mortality rate. “Not only do bees not die,” says Saar Safra, Beewise’s CEO. “They thrive.” Disponivel em: . Acesso em: 30 maio 2021. Com base no texto acima, é INCORRETO afirmar que A) a ciência desconhece as causas da mortandade de abelhas. B) as abelhas podem morrer por ausência de ações preventivas. C) a inteligência artificial pode ser usada para proteger apiários. D) Beewise pode ajudar no aumento da produção de mel.

It might not be the slickest thing on four wheels, and it definitely won't win any time trials, but Chinese logistics firm Cainiao's new Xiao G delivery cart could be the future. Every hour, the three-foot by five-foot automated vehicle picks up packages from Cainiao’s depot in Hangzhou—a city of 10 million people in China’s booming east—and tours a nearby neighborhood. Locals in pajamas pop down to meet the driverless cart at their nearest delivery point and type in a reference number. A door in the vehicle’s side flips open and the customer's parcel can be retrieved. Xiao G heads onto the next stop, weaving ponderously through traffic via 360-degree sensors. “It sends a message to customers after setting off and another when it arrives at a pick-up point so they know to come down,” says Cainiao engineer Long Fei. “Some models allow customers to drop off as well as pick up packages.” In terms of innovations in logistics, Xiao G may not be as earth-shaking as the shipping container or the cargo jet. But it is the most visible aspect of a stealthy revolution powered by Cainiao, which was founded in 2014. The $10 billion subsidiary of e-commerce giant Alibaba says it is poised to transform worldwide trade. Disponivel em: . Acesso em: 16 maio 2021. Based on this text about the Chinese logistics firm Cainiao’s new delivery cart, we can infer that |. customers may pick up their product and also send packages using Xiao G. Il. it may influence how businesses in other parts of the world deliver products. Ill. it will probably be more impactful in logistics than shipping containers. IV. it can move fast through heavy city traffics using 360-degree sensors. V. it relies on mobile technology and driverless vehicles to make its deliveries. Assinale a alternativa que apresenta as afirmativas corretas. A) Apenas |e IV. B) Apenas llle V. C) Apenas lleV. D) Apenas le Ill.
