When Napoleon needed money, he sold Jefferson the Louisiana
Purchase, which he had acquired when he conquered Spain. To find out what he'd
just purchased, Jefferson sent Merriweather Lewis and William Clark to explore
it. It covered an area from Louisiana northward to Missouri and across the
biggest part of the Great Plains and Northwest. The team which went with them
included such diverse people as Sacajawea, a Shoshone Indian and her baby Lewis's
slave, French trappers, woodsmen, and other interpreters. Lewis concentrated on
cataloging what they found, such as the various Native American tribes,
animals, and plants, and mapping the region, while Clark was the woodsman who
led the expedition. They went through many hardships, though miraculously only
one member of the expedition died over the several years they were gone. At one
point they were starving in the Rocky Mountains--there was not enough fat on
the deer they shot to keep them alive. They found an Indian tribe to barter
with, but the chief refused to deal with them until Sacajawea walked in--she
was his sister, who had been kidnapped from the tribe at the age of 5! Needless
to say, they got their food. They made it to the Pacific Ocean, where they then
split into two groups, one of which took a more southerly route back.
The power of the settlement work translated to a broad social engagement of Jane Addams in which she combined here work for Hull House with a comparably passionate contribution to the peace movement during the First World War. That earned her the nickname Saint Jane.
The answer is B. Germany's invasion of Poland.

Staph, as well as other pathogens, may change genetically by means of plasmids. Plasmids are DNA molecules which carries a rich diversity of genes that benefit the host cell. In this specific case, the host cell is the Staph bacteium. Among other things, plasmids carry antibiotic resistance genes.
<span>To illustrate how an ordinary Staph aureus bacterium can evolve into a methicillin-resistant bacterium, let's use the patient who doesn't finish an antibiotic prescription of penicillin. The Staph is weakened but not killed. Bacterial plasmids work quickly to produce genes that make the bacteria resistant to the drug. These parent bacteria replicate and pass on the plasmids, along with the DNA they contain, to the "daughter" cells. Voila! Methicillin-resistant Staphylococcus aureus! With the new DNA in place, each subsequent generation of Staph will also be resistant. But do not think for one moment that MRSA is otherwise somehow different from Staphylococcus aureus. MRSA IS Staph. Staph with an added feature. </span>
