Giraffes’ towering height is the key to their ability to survive in their often-dry habitat. It allows them to reach the tender leaves at the top of acacia trees. Because these leaves are about three-quarters water, they also provide moisture when there are no watering places nearby. Giraffes didn’t just decide to grow longer necks to reach these leaves! Over hundreds of generations, the tallest giraffes, who could reach more leaves, became healthier, lived longer, and had more offspring. Gradually, the average height increased .3.

4. Summarize the paragraph.

The tallest land animals in the world and the largest of Earth's grazing ungulates, giraffes (Giraffa camelopardalis) live in the savanna grasslands of sub-Sarahan Africa. Giraffes exhibit several characteristics developed through their evolution in a grassland environment in which scattered trees offer a food source most other species cannot utilize, water can be scarce and predators abound.

Explanation:

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.
