Os estudos históricos por muito tempo explicaram as relações entre Portugal e Brasil por meio da noção de pacto colonial ou exclusivo comercial. Sobre esse conceito, é correto afirmar que:
If apes go extinct, so could entire forests
Bonobos eat a lot of fruit, and fruit contains seeds.
Those seeds travel through a bonobo’s digestive system
while bonobo itself travels around the forest. A few hours
later, the seeds end up being deposited far from where the
fruits were plucked. And that is where the new trees come
from.
According to a paper recently published, if the
bonobos disappeared, the plants would also likely go
extinct, for many trees and plants species in Congo rely
almost exclusively on bonobos for seed dispersal.
The bonobo has two major functions here. First of all,
many seeds will not germinate well unless they have been
“handled” by another species. Stomach acids and intestinal
processes make the seed more able to absorb water and
later sprout.
Secondly, many seeds will not succeed if they remain
too close to their parental trees. The seeds that fell to the
ground near their parents did not survive because they
were choked off by the nearby plants. The bonobos eat
about 3,5 hours every day and travel a mean of 1.2
kilometers from meal sites before defecating.

Quanto seja louvável a um príncipe manter a fé, aparentar virtudes e viver com integridade, não com astúcia, todos o compreendem; contudo, observa-se, pela experiência, em nossos tempos, que houve príncipes que fizeram grandes coisas, mas em pouca conta tiveram a palavra dada, e souberam, pela astúcia, transtornar a cabeça dos homens, superando, enfim, os que foram leais (...). Um príncipe prudente não pode nem deve guardar a palavra dada quando isso se lhe torne prejudicial e quando as causas que o determinaram cessem de existir. (Nicolau Maquiavel, O Príncipe. São Paulo: Nova Cultural, 1997, p. 73-85.) A partir desse excerto da obra, publicada em 1513, é correto afirmar que:
