The central idea of paragraph 3 is that wind helped bring plant and animal life to Hawaii. Which sentence from the paragraph best conveys that central idea? "Many of Hawaii's plants, spiders, and insects have origins in Asia, thanks to a torrent of thin air called the jet stream, which roars across the upper atmosphere with hurricane force." B "Each January, the eastward-flowing jet stream makes a southerly meander over Asia." C "As the wind in the jet stream moves away from Asia, it slows to a minimum of about 110 kph just over Hawaii.- D "The entire joumey can take just four hours!”

I think the answer is B :)

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.
