A acácia-de-espigas, uma das plantas invasoras que causam mais impactos negativos no litoral português, produz milhares de sementes anualmente, que vão se acumulando no solo por várias décadas, promovendo a rápida invasão de áreas. Para realizar um controle natural, pesquisadores utilizaram o inseto australiano Trichilogaster acaciaelongifoliae, cuja função é colocar ovos nas gemas florais e vegetativas da acácia-de-espigas, estruturas nas quais se formariam as flores ou novos ramos. Dessa forma, o inseto australiano consegue diminuir a capacidade reprodutiva da planta e, consequentemente, diminui a invasão de novas áreas.

Leia o trecho do romance Memórias póstumas de Brás Cubas, de Machado de Assis, para responder à questão.
A propósito das botas
Meu pai, que não me esperava, abraçou-me cheio de ternura e agradecimento. “— Agora é deveras?, disse ele. Posso enfim...?”
Deixei-o nessa reticência, e fui descalçar as botas, que estavam apertadas. Uma vez aliviado, respirei à larga, e deitei- me a fio comprido, enquanto os pés, e todo eu atrás deles, entrávamos numa relativa bem-aventurança. Então considerei que as botas apertadas são uma das maiores venturas da Terra, porque, fazendo doer os pés, dão azo ao prazer de as descalçar. Mortifica os pés, desgraçado, desmortifica-os depois, e aí tens a felicidade barata, ao sabor dos sapateiros e de Epicuro1. [...] Quatro ou cinco dias depois, saboreava esse rápido, inefável e incoercível momento de gozo, que sucede a uma dor pungente, a uma preocupação, a um incômodo... Daqui inferi eu que a vida é o mais engenhoso dos fenômenos, porque só aguça a fome, com o fim de deparar a ocasião de comer, e não inventou os calos, senão porque eles aperfeiçoam a felicidade terrestre. Em verdade vos digo que toda a sabedoria humana não vale um par de botas curtas.
Tu, minha Eugênia, é que não as descalçaste nunca; foste aí pela estrada da vida, manquejando da perna e do amor, triste como os enterros pobres, solitária, calada, laboriosa, até que vieste também para esta outra margem...
(Memórias póstumas de Brás Cubas, 2008.)

Leia o poema “Vaso chinês”, de Alberto de Oliveira, para responder à questão.
Vaso chinês
Estranho mimo aquele vaso! Vi-o.
Casualmente, uma vez, de um perfumado
Contador1 sobre o mármor2 luzidio,
Entre um leque e o começo de um bordado.
Fino artista chinês, enamorado,
Nele pusera o coração doentio
Em rubras flores de um sutil lavrado,
Na tinta ardente, de um calor sombrio.
Mas, talvez por contraste à desventura,
Quem o sabe?... de um velho mandarim
Também lá estava a singular figura;
Que arte em pintá-la! a gente acaso vendo-a,
Sentia um não sei quê com aquele chim3
De olhos cortados à feição de amêndoa.

You may want to skip the toppings on your next hot dog, or skip it altogether: Health researchers at the University of Michigan have found that eating a single hot dog could take 36 minutes off your life. In their study, researchers looked at 5,853 foods in the US diet and measured their effects in minutes of healthy life gained or lost. “We wanted to make a health-based evaluation of the beneficial and detrimental impacts of the food in the entire diet,” Olivier Jolliet, professor of environmental health sciences at the university and senior author of the paper, told CNN.
The team came up with an index that calculates the net beneficial or detrimental health burden in minutes of healthy life associated with a serving of food. It’s based on a study called the Global Burden of Disease, which measures morbidity associated with a person’s food choices. “For example, 0.45 minutes are lost per gram of processed meat, or 0.1 minutes are gained per gram of fruit. We then look at the composition of each food and then multiplied this number by the corresponding food profiles that we previously developed,” said the professor.
One of the foods researchers measured was a standard beef hot dog on a bun. Its 61 grams of processed meat resulted in the loss of 27 minutes of healthy life, Jolliet said — but when ingredients like sodium and trans fatty acids were factored in, the final value was 36 minutes lost. Consumption of foods such as nuts, legumes, seafood, fruits and nonstarchy vegetables, on the other hand, have positive effects on health, the study found. “The index is primarily there to help aid in selecting and using calories consumed on a daily basis to tweak a minimum of habits and make the minimum of change to obtain a maximum benefit for health and the environment from our food experience,” Jolliet said.
