The History of the Maori
The arrival of the Maori people to New Zealand is deemed as somewhat of a mystery. It is estimated that the first Polynesians arrived over 1000 years ago, possibly around 800 AD or even earlier. Linguistic and cultural evidence suggests that the Maori travelled originally from the Cook Islands - an enormous feat at that time considering the prevailing winds make sailing in a southeast direction extremely difficult. It is because of this that the first navigators probably came here by design, looking for land whose presence may have been indicated by migratory birds, still flying these paths today. It is unknown if these first explorers actually settled here, or if in fact they returned to the Rarotongan Islands to herald the migration.
By the end of the fourteenth century, settlement was established throughout the country, most
being in the warmer climes of the north, being closer to that of their origins. Being Neolithic, devoid
of hides and textiles, they clothed themselves in cloaks constructed with woven flax and adorned
with dog fur or feathers provided by many native birds including kiwi and moa. The northern
conditions were favorable for many of the subtropical food plants they brought with them, in
particular the sweet potato, or Kumara. The Maori people also lived off the abundant produce
provided by native birds and the sea. In the south the bird life was hunted to extinction, the most
famous of which being the Moa, the spectacular flightless bird that could reach up to 3.7m in
height.

Leia atentamente cada uma das afirmativas relacionadas ao texto I, a seguir, e marque a alternativa correta:
I. Tomando-se a totalidade do texto, é possível dizer que seu autor usa como estratégia de apresentação do assunto em pauta um modelo teatralizado e que usa também recursos da oralidade.
II. A afirmativa “Os matemáticos da época achavam que popularizar o cálculo era o mesmo que jogar pérolas aos porcos.” retrata uma academia fechada em si mesma, pouco interessada na difusão do conhecimento.
III. As constatações da história da matemática dão conta de que as civilizações ocidentais, como a grega, foram precursoras na abstração necessária para que se conceba o conceito de zero.
“Só as obedece como e quando bem entende. “Assim faço a diferença”, costuma dizer. Mas não é nem um pouco egoísta.” (1º parágrafo)
Assinale a única opção que apresenta construção de estilo diverso do trecho destacado acima, transcrita do texto I.
“Se essa dialética parece complicada para você, cidadão do século XXI, imagine para as tribos primitivas que viveram muitos séculos antes de Cristo”. (3º parágrafo, texto I)
A ideia contida no trecho acima, sobretudo na palavra em destaque, encontra-se nos fragmentos abaixo, referentes ao texto I, exceto em:
O dispositivo a seguir utiliza a radiação solar para quantificar variações em propriedades termodinâmicas.
Este dispositivo é composto por uma lente convergente e por um porta-amostras. A lente possui área útil
de 80,0 cm2
, absortividade (α) de 20% e transmissividade 
de 80%. O porta-amostras possui
absortividade de 100% e volume variável, operando à pressão constante de 1,0 atm.
Em um procedimento experimental, injetou-se 0,100 mol de uma substância pura líquida no porta-amostras
do dispositivo. Em seguida, mediu-se um tempo de 15,0 min para a vaporização total da
amostra, durante o qual a irradiação solar permaneceu constante e igual a 750 W/m2
. Nesse processo, a
temperatura do porta-amostras estabilizou-se em 351 K. No experimento, o calor sensível da amostra e a
radiação emitida pelo porta-amostras são desprezíveis. Pode-se concluir que na vaporização total da
substância, as variações de entalpia molar padrão e de entropia molar padrão são, respectivamente:
O gráfico abaixo ilustra as variações de energia devido a uma reação química conduzida nas mesmas condições iniciais de temperatura, pressão, volume de reator e quantidades de reagentes em dois sistemas diferentes. Estes sistemas diferem apenas pela presença de catalisador. Com base no gráfico, é possível afirmar que:
Um erlenmeyer contém 10,0 mL de uma solução de ácido clorídrico, juntamente com algumas gotas de uma solução de fenolftaleína. De uma bureta, foi-se gotejando uma solução 0,100 M de hidróxido de sódio até o aparecimento de leve coloração rósea. Nesse momento, observou-se um consumo de 20,0 mL da solução alcalina. Pode-se afirmar que a concentração de HCl na solução ácida original era de:
