Considere um quadrado ABCD, de lado “a”. No segmento AD, os pontos E e F dividem esse lado em três segmentos congruentes, isto é, AE = EF = FD. No segmento BC, o ponto G é tal que BG = GC. Em seguida, o segmento BG é dividido em três segmentos congruentes pelos pontos H e I, de modo que BH = HI = IG. Por fim, no segmento AE, os pontos J e L dividem esse segmento em três partes congruentes, isto é, AJ = JL= LE.

    The Brazilian National Common Curricular Base (BNCC) introduced a significant paradigm shift by framing the English language as a mandatory curriculum component within an English as a Lingua Franca (ELF) perspective. This framework recognizes English as a global language used dynamically in multilingual settings, meaning that its instruction does not need to adhere strictly to the linguistic or cultural norms of native speakers from hegemonic countries. Consequently, English is no longer categorized merely as a traditional "foreign language" in Brazil, but rather as a widespread instrument of international communication.
     Furthermore, the BNCC justifies the inclusion of English within the curriculum as an essential element of a critical education agenda. Instead of focusing on a purely instrumental or mechanical view of grammar, the official guidelines underscore the formative function of the language, linking it to the social and political dimensions of communication. Learning English under this light is equated with equipping students with the necessary knowledge to enable wider global interaction, social mobility, and active citizenship.

Read the following statements about the use of linking words in English and their logical functions, based on the framework proposed by Halliday & Hasan (1976). The authors classify linking words (conjunctive adjuncts) into four semantic categories: additive, adversative, causal, and temporal. This classification underpins the analysis required in this question.
I- “Furthermore” is an additive linking word used to introduce an idea that reinforces or expands upon a previously stated point, and it is typically found in formal or academic registers.
II- “Nevertheless” and “however” are both adversative connectives that establish a contrast with the preceding clause or sentence; they are interchangeable in all contexts without difference in emphasis or position.
III- “Therefore” is a causal-resultative connective: it introduces a conclusion or consequence that logically follows from information already presented.
IV- “Meanwhile” belongs to the temporal category of linking words and is used to indicate that two actions or situations occur simultaneously or overlap in time.
Considering the semantic functions of linking words as classified by Halliday & Hasan (1976), mark the CORRECTalternative:

“Standardized testing has become the measuring stick of modern education – precise, efficient, and deeply inadequate. It tells us what students can recall under pressure, not what they can think when no one is watching. The highest-performing countries in international rankings have, paradoxically, begun dismantling their test-heavy curricula in search of something harder to measure: genuine understanding.” Source: adapted from an opinion column on education policy — genre: op-ed

Students using A.I. over humans to learn English (23rd December 2024)

    More and more students in Japan are using artificial intelligence (AI) to learn English and other languages. The languagelearning app Duolingo conducted a survey on how students study languages. More than 4,700 Japanese students answered questions about their language-learning habits. The survey found that the number of people using ChatGPTand other AI tools increased by more than 80 per cent in 2024. AI was particularly popular with younger people. The researchers said more young people used AI than took face-to-face lessons. However, some people in their 20s were not totally happy with AI lessons. They said AI lacked natural responses and was a little boring.
    Duolingo said: "We're in the midst of an AI revolution.…Technology has long had an impact on language learning." It found that apps were the most popular method in Japan to learn languages. English was the most studied language, followed by Korean. People are studying Korean "to understand the language as spoken by…favourite artists and celebrities." Duolingo said around 58 per cent of people who took the survey used language-learning apps. This was followed by video streaming platforms like YouTube and Netflix (37%), textbooks (36%) and online lessons (16%). The number of people going to a language school is decreasing. Just 13.8 per cent of people went to classes with a teacher.
