This is really hard to estimate, as it's not exactly perfectly clear which parts of economy are tourism (which of the transportations? are museums tourism or education?) and we have only estimates. Some of the estimates I have seen judge tourism to be only 6th ot 7th industry (but none of the options propose this!), but others say that it's third, so I'd go with a) - but definitely not c) or b). First is still food (agriculture, farming, etc)<span />
One of the main reasons why farmers opposed the gold standard was because food prices were generally rising and reverting to the gold standard would have kept prices constant .

The 1851 Treaty of Fort Laramie was an attempt to get the various Native American tribal nations to agree on boundaries and to stop fighting with one another, as well as allowing safe travel to settlers traveling the Oregon Trail. The treaty was broken soon after it was made, as the Lakota and Cheyenne peoples battled with the Crow, and further problems followed. A second Treaty of Fort Laramie was signed between the US government and a number of Indian nations in 1868, after the failure of that first treaty.</span>
