The security risks faced by Parliaments, legislatures, elected representatives, and the officials who support them, differ greatly according to their evolving national and local circumstances, among other things. For some, the biggest security risks may stem from disruptive protesters and cyber criminals, but terrorism may pose the most concerning risks for others. In fact, threat actors differ enormously in their intentions and capabilities, which also change over time.

Given that risk is a product of threat, vulnerability, and impact, it follows that ultimately there are only three ways to reduce security risk — namely, by reducing the threat, reducing the vulnerability, or reducing the impact (or some combination thereof). Reducing the threat element of security risk is difficult, especially in the case of determined and capable threat actors. Responsibility for reducing threats tends to lie mainly with national law enforcement, security, and intelligence agencies. That said, parliaments and other organisations can contribute to threat reduction through deterrence — in other words, by influencing the intentions of threat actors. Carefully crafted security-minded communications can convey a discouraging message to potential attackers, to the effect that they should expect to confront professional security measures and face a substantial risk of being caught. For instance, a parliamentary website might advertise that visitors will undergo ‘airport-style screening’, without explaining precisely what that entails. The public should be reassured by such message, whereas some threat actors might be deterred.

Paul Martin. Parliamentary security: an introductory guide. Internet: (adapted). Considering the preceding text, judge the following item.

Based on the text, it is correct to conclude that the possibility of threat reduction being successful varies according to the level of determination and to the ability of those posing threats.

n the second paragraph, both “Given that”, in “Given that risk is a product of threat”, and “to the effect that”, in “can convey a discouraging message to potential attackers, to the effect that they should expect to confront professional security measures” can be respectively replaced with Because and because without this changing the original meaning of the text.

Uma comissão da Câmara dos Deputados está analisando a distribuição de salários de determinada categoria funcional no Brasil. Durante um primeiro estudo promovido pelos deputados, um pesquisador calculou as médias, os desvios padrões e padronizou os valores dos salários brasileiros, para uma amostra de profissionais, com o intuito de comparar o desempenho salarial entre diferentes países.

Esse pesquisador observou que, no Brasil, o salário médio dessa categoria é de R$ 6.000 com desvio padrão de R$ 800, enquanto, em outro país — P —, usado na comparação, o valor tabelado, em dólar, do salário médio dessa mesma categoria é $ 3.500 e o desvio padrão é $ 250. Com base nessa situação hipotética, julgue o item seguinte.

Considere que, no Brasil, o salário de um indivíduo da citada categoria funcional, com determinado tempo de experiência, seja R$ 7.600, ao passo que, no país P, o salário de uma pessoa com o mesmo tempo de experiência do indivíduo citado seja $ 3.950. Nesse caso, após a padronização, o salário do indivíduo no Brasil é estatisticamente inferior ao da pessoa no país P.
