8 Read this passage from NASA about climate change. Based on the details in this paragraph, what is the best one-sentence summary?
Various natural physical processes modify the atmosphere, oceans and land surfaces on short and long-term scales. In the past 150 years, human
activities have resulted in significant changes in many aspects of Earth's environment, including increases in greenhouse gas concentrations,
modifications of the nitrogen and phosphorous cycle and major alterations of land use (e. g., deforestation). It is crucial that we understand the
Interaction of human-caused alterations and natural changes to predict future changes in the Earth's environment. In turn, this information will assist
sustainable development in relation to human activities while minimizing degradation of the environment and limiting the vulnerability of society to
climate change.
All of the damage to Earth's environment has occurred in the last 150 years, so it will be fairly easy for scientists to limit the damage of climate
change in the future.
Climate change is a name that describes all of the natural processes that man cannot control.
Climate change is entirely caused by the actions of people that have altered land use and increased greenhouse gas concentrations.
It is important to study how human-caused changes and natural changes are both affecting the earth in order to make predictions about what might

i believe that dan is so anxious because he dose not know what awaits him when he gets there. but i dont know to be honest

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

analyze the effectiveness of this excerpt. how does it function within the speech as a whole? how does the structure of the excerpt to convey the speech's purpose and key points? support your argument with evidence from the speech. (10 points)

many battles and wars (such as the one at gettysburg), are commemorated by statues or monuments, with some areas preserved as monuments and national parks. do you think this contradicts the message of "grass"? in at least 200 words, explain your thinking and cite evidence from the poem to support your opinion.
