Answer:
The correct answer is c) break a pledge he had made not to seek another term in office.
Explanation:
Roosevelt, after finishing his second term as the president, made the decision not to appear again for the presidency and decided to go on an expedition to Africa.
After returning from Africa, he finds William Howard Taft as president. He is not satisfied with the policies that William Taft develops, so Roosevelt decides to break his promise not to return to the presidency.
Roosevelt tries to return to the mandate, but it is not easy, he joins the progressive party, and although he did better than Taft, the candidate Woodrow Wilson wins the elections.

Answer:
The conclusion is false, because it is assuming that correlation = causation.
Explanation:
An important principle in statistical analysis is the principle that when correlation exist between two variables or more, it does not mean that one of the variables are causing the other to appear in a certain manner.
Remember that correlation means that you are investigating whether a relationships exists between two variables; in this example, as we can see, it is between the biodiversity in an ecosystem and the population of an insect.
The graph can be said to illustrate the result of the research; that as the biodiversity of the ecosystem goes down, the insect's population goes up. This is a form of negative correlation.
However - we do not know what is the direction of the relationship; the student concludes that as some insects die within the ecosystem, the researched insect's population goes up; assuming that the predator species died off and thus the researched insect's population increases.
Yet, it is also possible for the relationship to go towards the other direction; the researched insect population increases - perhaps by the introduction of a new food source that causes the species' population to increase - and thus, this damages the biodiversity of the ecosystem, making the population go down since it is possible that the researched insect is instead the species which is on top of the food chain at that ecosystem.
To investigate the direction of a relationship, further research need to be done and more sophisticated statistical methods need to be used.
