I. Assim sendo, enquanto a análise fonética se preocupa tão somente com a articulação, a fonêmica atenta somente para o fonema que, reunindo um feixe de traços que o distingue de outro fonema, permite a comunicação linguística.
II. A fonética pode reconhecer, e realmente o faz, diversas realizações para o / t/ da série ta-te-ti-to-tu; a fonêmica não leva em conta as variações (que se chamam alofones), porque delas não tomam conhecimento os falantes de língua portuguesa.
III. Um fonema admite uma gama variada de realizações fonéticas que vai até a conservação da integridade do vocábulo: quando isto não ocorre, diz-se que houve mudança de fonema.

Está CORRETO o que se afirma em:
Texto III para responder à questão.
Bons tempos os que vivemos, em que tudo tem prazo de validade e tudo pode ser descartável. Meu pai herdara uma máquina fotográfica do meu avô, foi com ela que registrou os primeiros passos de seus filhos, o batizado, a primeira comunhão, chegou mesmo a fotografar o casamento do irmão mais velho com o mesmo equipamento, que era chamado de “caixote”. Ainda tenho fotos tiradas por aquela ancestral das atuais câmaras digitais, que duram o espaço daquelas rosas de Malherbe.
Apesar de tanto e tamanho progresso tecnológico, muita coisa ainda precisa ser inventada e fatalmente o será; já disseram por aí que tudo o que homem pensa, mais cedo ou mais tarde pode ser realizado materialmente. A viagem à Lua, o submarino, aquele termômetro dentro do peito do peru para apitar na hora em que estiver pronto – são muitas as invenções do engenho humano, desde a roda dos sumérios ao “Jingle Bells” tocado nos celulares durante as festas do Natal.
De minha parte, já confessei que fiquei pasmo com uma das invenções do admirável mundo novo que muito me beneficiaram. Em criança, obrigavam-me a engraxar os sapatos, era quase uma exigência da higiene corporal andar de sapatos engraxados. E as latas de graxa eram insidiosas, custavam a ser abertas, batia-se com elas em algum lugar duro, ficavam amassadas e aí mesmo é que se recusavam a abrir.
Até que um gênio, maior do que Leonardo, maior do que Edison, inventou uma pequena alavanca lateral na parte de cima da lata. Se Arquimedes garantiu que levantaria a Terra se tivesse um ponto de apoio no espaço onde pudesse colocar uma alavanca, eu me senti um Arquimedes do Lins de Vasconcelos quando abri a primeira lata de graxa com a alavanquinha de metal ordinário que me abriu, mais do que uma lata de graxa, o território mágico da tecnologia moderna.
Mesmo assim, desconfio que falta muita coisa a ser inventada. Tenho um amigo que garante a facilidade com que poderemos viajar sem avião, trem, carro ou a pé. Aproveitando a rotação do nosso planeta, uma almanjarra qualquer que ainda será criada nos elevará a uma certa altura, lá de cima esperaremos que a Terra gire até ao ponto onde queremos saltar. Posso sair daqui da Lagoa ao meio-dia e meia e almoçar na Groenlândia a uma da tarde, sem esforço, sem apertões e por baixo custo. O problema é que – Deus é testemunha – não tenho nenhum interesse em almoçar ou jantar na Groenlândia.

Por que queima de canaviais ainda é permitida no país, apesar dos incêndios?
Os incêndios que se alastraram pelo interior de São Paulo, cobrindo o céu de muitas cidades e causando pânico e evacuações, chamou atenção para o uso do fogo nas chamadas queimas controladas da agricultura.
A situação é bastante comum no cultivo de cana-de-açúcar — os recentes incêndios atingiram principalmente os canaviais, queimando 100 mil hectares de lavouras e causando um prejuízo milionário aos produtores.
Os questionamentos se intensificaram quando um vídeo que mostra essa prática viralizou nas redes sociais.
Nas imagens, funcionários da usina da Delta Sucroenergia colocam fogo em uma plantação de cana. Até o dia 8 de setembro, 6,2 mil focos de incêndio foram registrados no Estado de São Paulo, sendo a maioria deles (pouco mais de 2,6 mil) em um só dia, 23 de agosto. É o maior desde 1998, quando o Instituto Nacional de Pesquisas Espaciais (Inpe) começou a fazer este tipo de levantamento.
A Delta refutou as acusações levantadas em redes sociais ao dizer que a queima havia sido feita em maio no interior de Minas Gerais, reforçou que a prática está prevista em lei e que toma medidas contra a propagação de incêndios nas plantações de cana.
As autoridades ambientais, cientes do vídeo, estiveram no local e não constataram irregularidades", disse a empresa em nota.
Esse tipo de queima controlada da palha da cana-de-açúcar ainda é realizada no Brasil, principalmente no Nordeste.
Segundo especialistas ouvidos pela BBC News Brasil, a técnica é usada quando o terreno de cultivo é mais acidentado, o que impede o uso de máquinas para a colheita.
Também ajuda a aumentar a produção e reduz a carga de trabalho para quem colhe a cana manualmente.
Mas isso só pode ser feito em épocas e condições meteorológicas específicas, com autorização e sob a fiscalização de autoridades.

Consider the dialogue below:
David: Hi, Emily! Have you ever thought about the impact of technology on our daily lives?
Emily: Hi, David! Yes, I think about it often. Technology has certainly made our lives easier in many ways, but it also has its downsides.
David: Absolutely. For example, smartphones have made communication much faster, but at the same time, people seem to be more disconnected in real life.
Emily: I agree. It's ironic, isn't it? We have more ways to connect, yet it sometimes feels like we're more isolated.
David: That's true. Do you think there's a way to find a balance between using technology and maintaining real-world connections?
Emily: I believe there is. Perhaps it's about setting boundaries, like limiting screen time or having tech-free days to spend more quality time with family and friends.
David: That's a good point. It might also be helpful to be more mindful about how we use technology.
Emily: Definitely. Being conscious of our usage can help us use technology more purposefully rather than letting it control us.
Based on the dialogue, which of the following statements best captures the main theme of their conversation?
Read the following excerpt:
"Critical reading involves analyzing, interpreting, and evaluating the text. When reading critically, a reader not only understands the content but also questions the author's intentions, the validity of the arguments, and the relevance of the evidence provided."
Based on the excerpt, which of the following actions demonstrates a critical reading strategy?

HVAC Contractors Need to Adapt to Repair Market
Repair or replace is a question homeowners often need to answer, and it greatly impacts an HVAC contractor's business. During COVID, the residential HVAC industry saw a replacement market boom. But in 2023 and now the beginning of 2024, there has been a shift to a repair market that HVAC contractors need to be aware of as they run their businesses.
According to numbers from the Air-Conditioning, Heating and Refrigeration Institute (AHRI), shipments of unitary air conditioners and heat pumps were down 16.7% in 2023, compared to 2022. Gas furnaces were down 23%.
"The replacement market is performing worse when you strip out new construction," said industry leader Matt Michel. "Housing starts were down around 5%, according to the St. Louis Federal Reserve, so the replacement market for unitary air conditioners and heat pumps was down in the low 20s."
Distributors are seeing similar numbers, according to the Heating, Air-conditioning, & Refrigeration Distributors International (HARDI).
"We definitely are seeing a shift here. And that shift has actually been visible for some time," said Tim Fisher, HARDI director of market intelligence.
HARDI receives data from FieldEdge on the invoice and quote trends exhibited by their users. Invoices reflect work that has been completed, whereas quotes reflect potential future work and are most often provided for new system installations. HARDI has found that, over time, the ratio of new invoices to new quotes is a useful indicator of whether a market is trending more toward repair than replace and vice versa.
The numbers show the annual growth rate bottomed out in the spring of 2022 but remained negative through most of the year, indicating that replacement trends were broadly higher in 2022 than in 2021. That figure increased through 2023, peaking in May but generally remaining positive for most of the year. While the three-month growth rate has slowed in recent months — an encouraging sign — they don't expect much of a negative drift in 2024, meaning that repair versus replace trends will broadly remain similar to where they were in 2023.
So why is this change happening? It can't be attributed to any single factor but rather a combination of items. Certainly, higher costs of both HVAC systems and housing in general play a role.
"Adapting to the economy is something contractors need to do. We can't just assume people are going to reach into their pocket and replace," said ACCA CEO Bart James. "Contractors need to help customers get through the current need. People are slowing down on their spending. People are worried about what is coming and how they are preparing for it. Wages and other things are not keeping up with how fast prices are going up."
James said reading the numbers shows there is a shift in the home improvement market.
"Just look at the Walmart and Home Depot quarterly projections. Walmart did well with more visits but had smaller purchases, while Home Depot did not hit their numbers. That tells you that people are handling investments into housing differently. That will catch up with HVAC, too. "Contractors need to prepare by making investments in their team to meet the needs of the customer. And that need is not always a replacement option but also can be a repair option," James continued.
The sluggish home resale market is another reason for the shift towards a repair market. "Home improvement spending, in aggregate, tends to follow existing home sales totals nationally," Fisher said. "People invest more in their homes prior to selling to boost its value, and new homeowners spend more in their first year of moving than homeowners who stay put. This has major implications for HVAC replacement demand, which, historically, peaks when existing home sales are at their highest and falls off when existing home sales decline.
"Both the 3-month and 12-month growth rates bottomed out earlier in 2023, and while still negative, have slowed significantly," he continued. "We believe that home sale totals are at or nearing their trough, and over the duration of 2024 should steadily improve and finish at or ahead of 2023 totals."
The final reason is the cyclical nature of HVAC. It reflects the shipment cliff from 15 years ago, when the industry contracted 40% after peak shipments in 2005. Contractors cannot replace what was never installed.
How do HVAC contractors deal with this shift? Michel believes they should embrace the repair market.
"The money is better in replacements," he said. "It always has been and always will be. However, margins are better in service. For the next couple of years, anyway, contractors should focus on building up their service business and making money on it."
Since service involves more labor, and labor carries more overhead than equipment and material, keeping a close watch on overhead expenses is a must.
"Contractors need to build the service base, watch your marketing expenses drop, and down the road, the replacement margins and close rates to a satisfied service base will rise," Michel said. "Once we get past the shipment cliff, the replacement market will begin a decade-long run with every year being better than the year before it. We know this because it's what happened in the past, and when it comes to replacements, the past truly is a prologue."
Contractors in most parts of the country are already feeling the pinch of a slower market, and their experiences in 2024 are unlikely to be much different from their experiences in 2023 though rebounds from the milder temperatures we saw during peak months last year would go a long way in improving demand in 2024.
HARDI advises contractors should consider the following six tactics in '24:
- •Offer financing options: Any homeowner considering a new system is likely going to feel some sticker shock if it's been a few years since they
- last bought a system. Financing a new system helps to alleviate that shock, making the big sticker prices much more palatable monthly payments.
- •Protect margins: Work to ensure that your pricing for jobs is consistent with market trends, and attempt to pass through as much of the higher system costs as possible. Likewise, now is a critical time to manage operating expenses closely. Together, good cost management and smart pricing can help protect business margins in 2024.
- •Educate homeowners: Many homeowners may not fully understand the long-term benefits of replacing their HVAC system versus frequent repairs. Offer educational materials, such as blog posts, videos, or pamphlets, explaining the advantages of a new system
- in terms of energy efficiency, lower maintenance costs, and improved IAQ. Also, be sure to make clear to your customers which incentives they may qualify for through IRA or other state-level rebate/incentive programs.
- •Focus on value proposition: Emphasize the value proposition of a new HVAC system, highlighting its reliability, longevity, and performance. Help homeowners understand that investing in a replacement now can save them money and hassle in the long run.
- •Offer maintenance packages: Create maintenance packages that bundle regular servicing with discounts on repairs or replacements. This can encourage homeowners to invest in preventive maintenance and build a long-term relationship with your company.
- •Diversify services: Explore diversifying your services beyond just HVAC installations and repairs. For example, you could offer IAQ assessments, smart thermostat installations, or energy audits to provide additional value to homeowners and generate new revenue streams.
