Write true or false in the blank following each statement to indicate whether it is accurate or not.
a) the existence of the supercontinent pangea led to a high degree of geographic uniqueness (endemism) among species during the late triassic.
b) the jurassic period marks the time when dinosaurs began to dominate among terrestrial vertebrates.
c) the scarcity of sediments from the middle jurassic may explain the apparent decrease in dinosaur diversity during this time.
d) mammals and dinosaurs co-existed throughout the jurassic and cretaceous periods.
e) the greatest leap in dinosaur diversity occurred during the jurassic period.
f) there is a correlation between the rise of angiosperms and the diversity of herbivorous dinosaurs during the cretaceous period.
g) there is a significant body of evidence suggesting that dinosaur evolution was responsible for the simultaneous evolution of angiosperms.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
