I believe it was negative. When the colonist arrived from Spain to Latin America, many Natives died and were killed, and I do not think that is such a great thing. I believe that the discovery of Latin America did contribute to many new discoveries such as foods and the columbian exchange that changed the diets of Europeans which made people more healthy and live longer. However, all these discoveries of animals, and foods lead to famine, death, and disease among the Native Americans hence also leading to slavery due to the many deaths of Natives, the colonist needed workers so, slavery then happened.
In a way, this is a double edged sword. On one hand, the animals are needed to best test the effects, but on the other hand it can be seen as very unethical. Honestly, I don't really see a way around using the animals. Unless you get human volunteers, but there is no way to fully make them understand what they are getting themselves into which can turn unethical very, very fast. If all of a sudden one of your human volunteers decides that they do not want to be a part of the test anymore, there is noting you can do to reverse what has already been done.

Answer:
#
P(R I Q) = P(RnQ) / P(Q) = 0.1 Therefore P(RnQ) = 0.1 X 0.35 = 0.035 (The intersection in the centre of a Venn Diagram)
P(RnQ') = 0.15 In a Venn Diagram this is R but excluding the centre intersection with Q. Therefore P(R) = P(RnQ') + P(RnQ) = 0.15 + 0.035 = 0.185
P(RUQ) = 0.15 + 0.035 + 0.315 = 0.5 so 0.5 must be outside the Venn Diagram circles.
