telo118 [61]

Answer:

The answer is A) So the country could borrow in the future.

Explanation:

If a country does not pay its debt in full and at the right time, it affects the credibility of the country such that it will be difficult for the country to borrow again since the last time the country borrowed the country defaulted. However if a country pays its debt in full , it creates confidence for people to invest in government securities and so that the public debt can become another means of income for the government.This conclusion reached by Alexander Hamilton was based on the British Financial System which highly esteemed payment of debt in full and on time.

svp [43]

The correct answer to this open question is the following.

The question does not include options. However, we can answer it in the following way.

After Mateo, a student in your class reads a series of scientific articles discussing the value of multiple vitamin supplements in preventing heart disease, he approaches you and remarks, "I’m confused. If all of these scientists are studying the same issue and are all using the scientific method, why aren’t they all coming to the same conclusions?"

My response should emphasize the fact that studies and experiments include different data, scenarios, people, and the interpretation of results is not always the same. It varies according to the purpose of the study and the premises.

That is something important to consider in these kinds of studies. Scientists and researches often interpret the results according to their goals, experience, expectations, and variables. That is why there is a variety of conclusions regarding one topic of study.
