Costuma-se descrever a ciência como uma sucessão de descobertas, cada uma atribuída a uma mente excepcional. Essa descrição é mais simples e, por isso, mais confortável. Porém, é incompleta.

Ideias científicas não emergem no vazio. Elas dependem de um sistema que contém instrumentos, linguagem e dados acumulados, bem como de comunidades capazes de reconhecer e, principalmente, criticar seus significados. Para que haja um desfecho por orientação vetorial que conduza ao que conhecemos como a consagração de uma teoria, é preciso haver, sobretudo, convergência. Uma nova ideia pode se aproximar mais da verdade e, ainda assim, permanecer estéril se os vetores do sistema científico não estiverem suficientemente acoplados para absorvê-la.

Por outro lado, quando múltiplas linhas de evidência passam a operar de forma coerente, mesmo ideias inicialmente controversas tornam-se inevitáveis. A consequência é que a história da ciência é menos uma sucessão de lampejos isolados e mais a de sincronizações oriundas de massas de dados e ideias que vão gradualmente se articulando até que o peso de um novo paradigma se torne insustentável.

Julgue o item seguinte, com base nas ideias e construções linguísticas do texto precedente.

Na oração “Uma nova ideia pode se aproximar mais da verdade” (segundo parágrafo), o emprego do pronome “se” entre as formas verbais “pode” e “aproximar” é típico de textos informais, de modo que, para garantir a formalidade e a correção gramatical do texto, tal pronome deveria ser deslocado para a posição enclítica à forma verbal “aproximar”.

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.

In the excerpt “threat actors differ enormously in their intentions and capabilities, which also change over time” (first paragraph), “which” refers to “threat actors”.

The passage “some combination thereof”, in “reducing the threat, reducing the vulnerability, or reducing the impact (or some combination thereof)” (second paragraph), necessarily indicates a combination of the two last factors mentioned: vulnerability reduction and impact reduction.

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.
