O texto seguinte servirá de base para responder à questão. 

(1º§)It sits on the "line of contact" - an almost 500km (310 mile) long fissure between Ukrainian government territory and two enclaves that have been held by Russian backed separatists since 2014. Families, communities, and services are divided by this line. The enduring conflict here on the eastern front has already claimed more than 14,000 lives - at least 3,000 of them civilians, according to the United Nations.
(2º§)The self-styled Donetsk People's Republic (DNR) and Luhansk People's Republic (LNR) are recognised by no one - for now, not even the Kremlin - but they are home to about four million people. Larysa is one of them. She was wrapped up against the cold in a bright blue jacket, pink jumper, and matching woolly hat. She preferred not to use her last name.
(3º§)It takes permission and patience to get from Ukrainian government territory to the other side. Larysa knows the drill. "I do this every six months," she said. "I have been for a check-up at a hospital in Dnipro (in central Ukraine) and now I am going home to Donetsk." As she waited for sniffer dogs to check her bag, she wasn't too concerned about the Russian military build-up on Ukraine's borders.
(4º§)"We have been bombed, and we have been through a lot," she said."I don't believe there will be an invasion, or if there is, it won't be a big one. That's my view as someone with intuition. I watch TV and what politicians say. I think all of this is just to keep us on our toes and stop us from getting too relaxed."
(5º§)Perhaps. But Western leaders have long feared that President Vladimir Putin would fake a crisis in the Russian-backed rebel areas - or the appearance of one - to use as an excuse to invade. The seeds were sewn on Friday when rebel leaders announced that women and children would be evacuated over the border to Russia because Ukraine was planning to attack. Ukraine denied that and most civilians in those areas appear to have stayed put.
(6º§)"We, the people, do not want any war to happen. We want to live, love... We want to love everybody and give them a hug," said Larysa, eyes smiling above her mask. With that she boarded a bus to take her through no man's land to a checkpoint on the other side.

Q1902724 Inglês
    State and local governments regularly disclose financial information to the public so that the current financial status of the government is recognized publicly. The purpose of such disclosure is to achieve accountability and inform citizens about governments’ financial decisions. Despite the efforts to improve the accessibility and readability of financial information, we do not know whether and how the financial information is processed by citizens. This study investigates how citizens assess the financial condition of governments when different financial information is presented. We conduct an online survey experiment to understand how disclosed financial information shapes citizens’ perceived level of a government’s fiscal stress and their attitudes toward governments’ revenue-raising strategies. We find that citizens prioritize the financial indicators that they are familiar with, such as debt and surplus ratios. While both historical and social reference points play an important role, social reference is more effective in influencing citizens’ perception. We only find limited evidence to support the relationship between citizens’ perception of fiscal stress and their support toward governments’ decisions to raise revenues.

    Leaders at tech companies around the world could face up to two years in prison in the United Kingdom if they do not comply with new online safety laws.

    Draft legislation aims to crack down on social media and other online entities to ensure safety and privacy for users, particularly children. The laws were drafted to prevent uploading and spreading of harmful content such as racism, bullying, fraud and sexual abuse.

     While the legislation has been criticized by Parliament members in the past, the new draft has received bipartisan support.

     The bill has to be voted on by British lawmakers.

   The legislation has been updated several times since its inception. Among the changes are hefty fines or blockages if networks fail to remove harmful content after being notified of its existence, as well as the labeling of sending unsolicited nudes as a criminal offense.

    The fines could be up to 10 percent of the affected company’s annual global income. The Office of Communications (Ofcom), the bill’s regulator, has been granted legal grounds to request information from companies they suspect of not following the bill’s rules.

     If Ofcom is able to prove that the companies withheld information or have not responded properly to notifications of inappropriate or illegal content, the executives would be held criminally liable. This part of the law will be enforced two months after the law itself is enacted, meaning companies and websites will have time to crack down on their content before facing legal consequences.

    Some U.K. residents have pushed back against the new version of the bill, including memes from the Open Rights Group. The organization claims that, despite good intentions, the regulations could result in a slippery slope that could end up violating free speech.

    Information technology (IT) serves a critical role in state operations. State agencies and higher education institutions are increasingly reliant on the automated processing of information. It is important that the IT applications that process information have controls to ensure and protect the accuracy, integrity, reliability, and confidentiality of the State’s information.
     Due to the increased reliance on IT applications, a significant portion of the audits the State Auditor’s Office (SAO) performs include an IT component. Auditors select IT controls for testing during an audit based on a risk assessment. The risk assessment considers, among other factors, the objectives and scope of the audit. Therefore, the SAO does not test all IT controls in every audit, with the high-risk and high-impact IT controls being tested more frequently. In addition, to minimize security risks, the SAO does not publicly report sensitive IT audit issues, in accordance with the Texas Government Code, Section 552.139.

Q1901977 Inglês


    During a ransomware hack, attackers infiltrate a target’s computer system and encrypt its data. They then demand a payment before they will release the decryption key to free the system. This type of extortion has existed for decades, but in the 2010s it exploded in popularity, with online gangs holding local governments, infrastructure and even hospitals hostage. Ransomware is a collective problem—and solving it will require collaborative action from companies, the government and international partners.

     As long as victims keep paying, hackers will keep profiting from this type of attack. But cybersecurity experts are divided on whether the government should prohibit the paying of ransoms. Such a ban would disincentivize hackers, but it would also place some organizations in a moral quandary. For, say, a hospital, unlocking the computer systems as quickly as possible could be a matter of life or death for patients, and the fastest option may be to pay up.

     Collective action can help. If all organizations that fall victim to ransomware report their attacks, they will contribute to a trove of valuable data, which can be used to strike back against attackers. For example, certain ransomware gangs may use the exact same type of encryption in all their attacks. “White hat” hackers can and do study these trends, which allows them to retrieve and publish the decryption keys for specific types of ransomware. Many companies, however, remain reluctant to admit they have experienced a breach, wishing to avoid potential bad press. Overcoming that reluctance may require legislation, such as a bill introduced in the Senate last year that would require companies to report having paid a ransom within 24 hours of the transaction.

Can alternative tailings disposal become the norm in mining?

   There is no doubt that the resources extracted from mining are critical to our way of life. Likely, you’re reading this on your computer, smartphone, or tablet. Mining touches all our lives daily (in addition to metals used in electronics, think about that can of soda you are drinking, or the aggregate used to pave your driveway). The industry works hard to make sure the net impact is positive. 
   However, the waste associated with mining, both past and present, is an unavoidable result of conventional mineral processing. In the future it may be possible to extract metals like copper and gold without crushing and grinding the ore down to fine particle size and adding considerable quantities of liquid, resulting in conventional tailings.
    What are the challenges associated with conventional tailings? Well, it is all about water. Managing seepage from the tailings themselves, monitoring pore water pressure within the tailings dams or designing facilities to safely store or pass flood events. Because such a significant quantity of water is added during mineral processing, “conventional” tailings dams store the tailings as a slurry. Water within the tailing material is either evaporated, migrates as seepage or remains entrained within the tailings impoundment. Removing water prior to disposal through various means is considered “alternative” disposal. Mining low grades of ore has resulted in increased water use per unit of production. In some cases, the availability of water is one of the greatest constraints on mine development.

Q1891013 Inglês
      Mars is the fourth planet from the Sun — a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.

      No other planet has captured our collective imagination quite like Mars.

      In the late 1800s when people first observed the canal-like features on Mars’ surface, many speculated that an intelligent alien species resided there. This led to numerous stories about Martians, some of whom invade Earth, like in the 1938 radio drama, The War of the Worlds. According to an enduring urban legend, many listeners believed the story to be real news coverage of an invasion, causing widespread panic.

      Countless stories since have taken place on Mars or explored the possibilities of its Martian inhabitants. Movies like Total Recall (1990 and 2012) take us to a terraformed Mars and a struggling colony running out of air. A Martian colony and Earth have a prickly relationship in The Expanse television series and novels.

Q1891007 Inglês
      In a world where many of us are glued to our smartphones, Dulcie Cowling is something of an anomaly — she has ditched hers. The 36-year-old decided at the end of last year that getting rid of her handset would improve her mental health. So, over Christmas she told her family and friends that she was switching to an old Nokia phone that could only make and receive calls and text messages. 

      She recalls that one of the pivotal moments that led to her decision was a day at the park with her two boys, aged six and three: “I was on my mobile at a playground with the kids and I looked up and every single parent — there was up to 20 — were looking at their phones, just scrolling away,” she says. 

      “I thought ‘when did this happen?’. Everyone is missing out on real life. I don’t think you get to your death bed and think you should have spent more time on Twitter, or reading articles online.”

      Ms Cowling, who is a creative director at London-based advertising agency Hell Yeah!, adds that the idea to abandon her smartphone had built up during the covid-19 lockdowns.

      “I thought about how much of my life is spent looking at the phone and what else could I do. Being constantly connected to lots of services creates a lot of distractions, and is a lot for the brain to process.”

      She plans to use the time gained from quitting her smartphone to read and sleep more.

      About nine out of 10 people in the UK now own a smartphone, a figure broadly replicated across the developed world. And we are glued to them — one recent study found that the average person spends 4.8 hours a day on their handset.

      Yet for a small, but growing number of people, enough is enough.

      Alex Dunedin binned his smartphone two years ago. “Culturally we have become addicted to these tools,” says the educational researcher and technology expert. “They are blunting cognition and impeding productivity.”

      He has become happier and more productive since he stopped using a smartphone, he says. 

      Mr Dunedin doesn’t even have an old-fashioned mobile phone or even a landline anymore. He is instead only electronically contactable via emails to his home computer. 

     “It has improved my life,” he says. “My thoughts are freed up from constantly being cognitively connected to a machine that I need to feed with energy and money. I think that the danger of technologies is that they are emptying our lives.” 

      Yet, while some worry about how much time they spend on their handset, for millions of others they are a godsend. 

      “More than ever, access to healthcare, education, social services and often to our friends and family is digital, and the smartphone is an essential lifeline for people,” says a spokesperson for UK mobile network Vodafone. 

      “We also create resources to help people get the most from their tech, as well as to stay safe when they’re online — that’s hugely important.”
