During WWI, what was the exception of events that occurred after Curry and Roosevelt called up the Rough Riders?

The choice that highlights Many of the Rough Riders refusing to join in the fighting accurately reflects the sentiments and outcomes of the time. After the Rough Riders were called up during World War I, there were significant challenges related to participation. Many veterans from the original Rough Riders were older or had commitments that made active service difficult. Additionally, there was hesitation among some individuals about re-engaging in combat due to the complexities of modern warfare and the memories of past battles.

This option underscores the shift in attitudes toward warfare and the realities of mobilizing troops who may not have been ready or willing to go back into combat scenarios. The other options present more optimistic scenarios regarding troop organization, leadership, and eagerness to fight, which do not align with the reality faced by the Rough Riders during this period. This crucial distinction is what makes the selected option more relevant and accurate in the context of historical events related to the Rough Riders' involvement in World War I.
