In relation to the consumption of sugar, one can say, based on the text, that
According to the text,
The word “for”, in “for warmth and light bring ecological renewal to what is now an icy desert” (l.16-17), is used to introduce
Based on the article, it can be affirmed that
A afirmação a seguir apresenta alguns dos fundamentos de circuitos elétricos.
“... the algebraic sum of the voltages around any closed path in a circuit is identically zero for all time, and the algebraic sum of the currents injected in any closed surface is identically zero, also for all time ...” A afirmação indica queO texto a seguir descreve fontes de energia comumente utilizadas pela humanidade.
“... in one hand there are renewable resources, which are resources continually replenished, such as sunlight, wind, tides, waves and geothermal heat. On the other hand, there are non-renewable resources, which are resources consumed much faster than nature can generate them, such as coal, petroleum, and natural gas ...” Segundo o texto,A afirmação descreve um arranjo experimental composto por um amplificador operacional utilizado como subtrator.
“An ideal operational amplifier acting differentially as a subtractor, has an unitary gain. In this case, the output signal is given by the difference from the voltage signal connected to the negative terminal of the op-amp to the voltage signal connected to the positive one. When the voltage signal connected to the negative terminal is fifty volts (positive) and the voltage signal connected to the positive terminal is one hundred and fifty volts (negative), the output signal is two hundred volts (positive).” O texto descreve um arranjo experimental composto por um amplificador operacional na configuraçãoA afirmação descreve um equipamento elétrico empregado em sistemas elétricos de potência.
“The winding resistances of an ideal transformer are negligible, all the flux is confined to the core and the permeability of the core is infinite.” De acordo com a afirmação, um transformador ideal possui enrolamentos com resistênciaA seguinte afirmação apresenta considerações acerca do projeto de máquinas elétricas.
“There are numerous inherent shortcomings to the concept of magnetic circuits, except for the fact that it is the easiest design tool available for calculating fluxes in practical machinery design. Although the use of Maxwell’s equations produces exact results, this method demands considerable effort and does not present significant benefits, when compared to the results produced by the magnetic circuits’ method.” Assinale a alternativa que melhor descreve a afirmação.Um antônimo para a palavra biggest é

Judge the following item according to the text above.
The author uses engineering as an instance of specialization of
a field of knowledge in order to support his argument.
Judge the following item according to the text above.
According to the text, specialization arises from the need to
prevent certain dimensions of a field from becoming obsolete
after they had been recognized as established or traditional
areas.
According to the text above, judge the next item.
The text claims that engineers are as much responsible for the reduction of risks in modern society as any other professional, because they “cannot bear the total blame” (l.3).
1. Global warming is an increase in earth’s temperature. 2. Renewable energy is a natural and unlimited source of power. 3. Climate change is severe climate events such as tornados. 4. Ozone layer is a kind of wind power.

Every day thousands of teens wake up afraid to go to school. Bullying is a problem that affects millions of students, and it has everyone worried, not just the kids on its receiving end. Yet because parents, teachers, and other adults don’t always see it, they may not understand how extreme bullying can get.
Bullying is when a person is picked on over and over again by an individual or group with more power, either in terms of physical strength or social standing.
Two of the main reasons people are bullied are because of appearance and social status. Bullies pick on the people they think don’t fit in, maybe because of how they look, how they act (for example, kids who are shy and withdrawn), their race or religion, or because the bullies think their target may be gay or lesbian.
Some bullies attack their targets physically, which can mean anything from shoving or tripping to punching or hitting, or even sexual assault. Others use psychological control or verbal insults to put themselves in charge. For example, people in popular groups or cliques often bully people they categorize as different by excluding them or gossiping about them (psychological bullying). They may also taunt or tease their targets (verbal bullying).
Verbal bullying can also involve sending cruel texts, messages, or emails or posting insults about a person on Facebook or other sites — practices that are known as cyberbullying. Studies show that people who are abused by their peers are at risk for mental health problems, such as low self-esteem, stress, depression, or anxiety. They may also think about suicide more.
What is the topic of the text?
Underperforming middle years readers must first be motivated to engage and re-engage with texts. Specific reading skills can only develop as an outcome of that engagement. Engagement is an interactive process. It requires teachers to have a close knowledge of students and their reading, and so be able both to provide sufficiently challenging learning experiences as well as the necessary support for those experiences to ensure successful learning. Student engagement can only occur as they recognise that they can be successful partners in this process.
